Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation GP Strategies is a leading workforce transformation partner. References in this report to “GP Strategies,” the “Company,” “we” and “our” are to GP Strategies Corporation and its subsidiaries, collectively. The accompanying condensed consolidated balance sheet as of June 30, 2021, the condensed consolidated statements of operations, comprehensive income (loss) and stockholders' equity for the three and six months ended June 30, 2021 and 2020, and the condensed consolidated statements of cash flows for the six months ended June 30, 2021 and 2020 have not been audited, but have been prepared in conformity with U.S. generally accepted accounting principles (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2020, as presented in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020. In the opinion of management, this interim information includes all material adjustments, which are of a normal and recurring nature, necessary for a fair presentation. The results for the 2021 interim period are not necessarily indicative of results to be expected for the entire year. Effective July 1, 2020, we began managing our business under a new organizational structure on a regional basis through our three geographic markets, North America, Europe Middle East Africa (EMEA) and Emerging Markets (Latin America and Asia Pacific countries). These became our reportable segments in the third quarter of 2020. Prior to this change, our reportable segments consisted of two global practices, Workforce Excellence and Business Transformation Services, which focused on providing similar and/or complementary products and services across our diverse customer base within target markets. Effective January 1, 2021 as a result of a change in management, we transferred one of our businesses from our North America segment to our EMEA segment. In addition, we realigned some of our businesses between our North America Organizational Performance Solutions (OPS) and North America Technical Performance Solutions (TPS) to more accurately align with their focus industries. We have reclassified the segment financial information herein for the prior year periods to reflect the changes in our segment reporting and conform to the current year's presentation. The condensed consolidated financial statements include the operations of the Company and its subsidiaries. All significant intercompany balances and transactions have been eliminated. Certain prior year amounts have been reclassified to conform with the current year presentation. Use of Estimates and Assumptions The preparation of financial statements in conformity with U.S. GAAP requires us to employ estimates and make assumptions that affect the reported amounts of certain assets and liabilities, the revenues and expenses reported for the periods covered by the accompanying consolidated financial statements, and certain amounts disclosed in these Notes to the condensed consolidated financial statements. Although such estimates and assumptions are based on management’s most recent assessment of the underlying facts and circumstances utilizing the most current information available and past experience including considerations for potential impacts of the coronavirus (COVID-19) pandemic, actual results could differ significantly from those estimates and assumptions. Our estimates, judgments, and assumptions are evaluated periodically and adjusted accordingly. Please refer to Note 1- Significant Accounting Policies of the Notes to Consolidated Financial Statements included in our 2020 Form 10-K for a discussion of other significant estimates and assumptions affecting our consolidated financial statements.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Standards	Recent Accounting Standards Recently Adopted Accounting Standards In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12, Simplifying the Accounting for Income Taxes . The guidance issued in this update simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in Accounting Standards Codification (ASC) 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition for deferred tax liabilities for outside basis differences. ASU 2019-12 also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. We adopted the standard on January 1, 2021. The new standard did not impact our financial statements. For a discussion of other accounting standards that have been issued by the FASB but are not yet effective, refer to the Recent Accounting Standards section in our Annual Report on Form 10-K for the year ended December 31, 2020. These standards are not expected to have a material impact on our results of operations, financial condition or cash flows.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Significant Accounting Policy We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers (ASC Topic 606). Revenue is measured based on the consideration specified in a contract with a customer. Most of our contracts with customers contain transaction prices with fixed consideration, however, some contracts may contain variable consideration in the form of discounts, rebates, refunds, credits, price concessions, incentives, performance bonuses, penalties and other similar items. When a contract includes variable consideration, we evaluate the estimate of variable consideration to determine whether the estimate needs to be constrained; therefore, we include the variable consideration in the transaction price only to the extent that it is probable that a significant reversal of the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. We recognize revenue when we satisfy a performance obligation by transferring control over a product or service to a customer. This can result in recognition of revenue over time as we perform services or at a point in time when the deliverable is transferred to the customer, depending on an evaluation of the criteria for over time recognition in ASC Topic 606. Further details regarding our revenue recognition for various revenue streams are discussed below. Nature of goods and services Over 90% of our revenue is derived from services provided to our customers for training, consulting, technical, and other services. Less than 10% of our revenue is derived from various other offerings including custom magazine publications and assembly of glovebox portfolios for automotive manufacturers, licenses of software and other intellectual property, and software as a service (SaaS) arrangements. Our primary contract vehicles are time-and-materials, fixed price (including fixed-fee per transaction), and cost-reimbursable contracts. Each contract has different terms based on the scope, deliverables and complexity of the engagement, requiring us to make judgments and estimates about recognizing revenue. Under time-and-materials and cost-reimbursable contracts, the contractual billing schedules are based on the specified level of resources we are obligated to provide. Revenue under these contract types are recognized over time as services are performed as the client simultaneously receives and consumes the benefits provided by our performance throughout the engagement. The time and materials incurred for the period is the measure of performance and, therefore, revenue is recognized in that amount. For fixed price contracts which typically involve a discrete project, such as development of training content and materials, design of training processes, software implementation, or engineering projects, the contractual billing schedules are not necessarily based on the specified level of resources we are obligated to provide. These discrete projects generally do not contain milestones or other measures of performance. The majority of our fixed price contracts meet the criteria in ASC Topic 606 for over time revenue recognition. For these contracts, revenue is recognized using a costs incurred input method based on the relationship of costs incurred to total estimated costs expected to be incurred over the term of the contract. We believe this methodology is a reasonable measure of progress to depict the transfer of control to the customer since performance primarily involves personnel costs and services provided to the customer throughout the course of the projects through regular communications of progress toward completion and other project deliverables. In addition, the customer is required to pay us for the proportionate amount of our fees in the event of contract termination. A small portion of our fixed price contracts do not meet the criteria in ASC Topic 606 for over time revenue recognition. For these projects, we defer revenue recognition until the performance obligation is satisfied, which is generally when the final deliverable is provided to the client. The direct costs related to these projects are capitalized and then recognized as cost of revenue when the performance obligation is satisfied. For fixed price contracts, when total direct cost estimates exceed revenues, the estimated losses are recognized immediately. The use of the costs incurred input method requires significant judgment relative to estimating total contract costs, including assumptions relative to the length of time to complete the project, the nature and complexity of the work to be performed, and anticipated changes in estimated salaries and other costs. Estimates of total contract costs are continuously monitored during the term of the contract, and recorded revenues and costs are subject to revision as the contract progresses. When revisions in estimated contract revenues and costs are determined, such adjustments are recorded in the period in which they are first identified. Revenue recognized in the reporting period from performance obligations satisfied (or partially satisfied) in previous periods on our fixed price contracts in the aggregate resulted in a net increase (decrease) to revenue of $0.3 million and $(0.4) million for the three months ended June 30, 2021 and 2020, respectively, and $(0.2) million and $(0.5) million for the six months ended June 30, 2021 and 2020, respectively. For certain fixed-fee per transaction contracts, such as delivering training courses or conducting workshops, revenue is recognized during the period in which services are delivered in accordance with the pricing outlined in the contracts. For certain fixed-fee per transaction and fixed price contracts, such as for the shipping of publications and print materials, revenue is recognized at the point in time at which control is transferred which is upon delivery, as the overtime revenue recognition criteria are not met. Taxes assessed by a government authority that are both imposed on and concurrent with a specific revenue-producing transaction, that we collect from a customer, are excluded from revenue. Performance Obligations A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. As of June 30, 2021, we had $316.2 million of remaining performance obligations, which we also refer to as total backlog. We expect to recognize approximately 85 percent of our remaining performance obligations as revenue within the next twelve months. Contract Balances The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled revenue (contract assets), and deferred revenue (contract liabilities) on the condensed consolidated balance sheet. Amounts charged to our clients become billable according to the contract terms, which usually consider the passage of time, achievement of milestones or completion of the project. When billings occur after the work has been performed, such unbilled amounts will generally be billed and collected within 60 to 120 days but typically no longer than over the next twelve months. When we advance bill clients prior to the work being performed, generally, such amounts will be earned and recognized in revenue within the next twelve months. These assets and liabilities are reported on the condensed consolidated balance sheet on a contract-by-contract basis at the end of each reporting period. Changes in the contract asset and liability balances during the six-month period ended June 30, 2021 were not materially impacted by any other factors. We recognized revenue of $3.8 million and $3.2 million for the three months ended June 30, 2021 and 2020, respectively, and $8.2 million and $11.4 million for the six months ended June 30, 2021 and 2020, respectively, that was included in the contract liability balance at the beginning of the year and primarily represented revenue from services performed during the current period for which we received advance payment from clients in a prior period. Disaggregation of Revenue See Note 13 (Business Segments) to these Condensed Consolidated Financial Statements for our disaggregated revenues.

Significant Customers & Concentration of Credit Risk	Significant Customers & Concentration of Credit Risk We have a market concentration of revenue in both the automotive sector and financial & insurance sector. Revenue from the automotive sector accounted for approximately 25% and 24% of our consolidated revenue for the six months ended June 30, 2021 and 2020, respectively. In addition, we have a concentration of revenue from a single automotive customer, which accounted for approximately 15% and 13% of our consolidated revenue for the six months ended June 30, 2021 and 2020, respectively. As of June 30, 2021, accounts receivable from a single automotive customer totaled $20.5 million, or 20%, of our consolidated accounts receivable balance. Revenue from the financial & insurance sector accounted for approximately 17% and 16% of our consolidated revenue for the six months ended June 30, 2021 and 2020, respectively. In addition, we have a concentration of revenue from a single financial services customer, which accounted for approximately 9% of our consolidated revenue for the six months ended June 30, 2021 and 2020, respectively. As of June 30, 2021, billed and unbilled accounts receivable from a single financial services customer totaled $9.5 million, or 7%, of our consolidated accounts receivable and unbilled revenue balances.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic earnings (loss) per share (EPS) is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution of common stock equivalent shares that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. Our dilutive common stock equivalent shares consist of restricted stock units computed under the treasury stock method, using the average market price during the period. Performance-based restricted stock unit awards are included in the computation of diluted shares based on the probable outcome of the underlying performance conditions being achieved. The following table presents instruments which were not dilutive and were excluded from the computation of diluted EPS in each period, as well as the dilutive common stock equivalent shares which were included in the computation of diluted EPS (in thousands): Three Months Ended Six Months Ended 2021 2020 2021 2020 Non-dilutive instruments — 132 — 84 Dilutive common stock equivalents 868 63 848 49

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets	Intangible Assets Goodwill Goodwill represents costs in excess of values assigned to the underlying net assets of acquired businesses. Intangible assets acquired are recorded at estimated fair value. Goodwill is deemed to have an indefinite life and is not amortized, but is tested for impairment annually during the fourth quarter, and at any time when events suggest an impairment more likely than not has occurred. We test goodwill at the reporting unit level. ASC Topic 350, Intangibles - Goodwill and Other (ASC Topic 350), permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a quantitative goodwill impairment test. Under ASC Topic 350, an entity is not required to perform a quantitative goodwill impairment test for a reporting unit if it is more likely than not that its fair value is greater than its carrying amount. A reporting unit is an operating segment, or one level below an operating segment, as defined by U.S. GAAP. Our North America operating segment is comprised of three reporting units based on our primary solution sets. The remaining three reporting units are our EMEA, Latin America and Asia Pacific operating segments. Effective January 1, 2021 as a result of a change in management, we transferred one of our businesses from our North America segment to our EMEA segment. In addition, we realigned some of our businesses between our North America OPS and North America TPS reporting units to more accurately align with their focus industries. As a result of these changes, we determined a triggering event occurred and performed a quantitative goodwill impairment test. For the goodwill impairment test as of January 1, 2021, we concluded that the fair values of each of our reporting units exceeded their respective carrying values. In the quantitative impairment test, we compare the fair value of each reporting unit to its carrying value. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that reporting unit, goodwill is not impaired and we are not required to perform further testing. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then we record an impairment loss equal to the difference, however, the loss recognized would not exceed the total amount of goodwill allocated to the reporting unit. We concluded that each of our reporting units had excess fair values greater than their respective carrying values and that there was no indication of impairment. We determine the fair value of our reporting units using a market approach. Under the market approach, we perform a comparable public company analysis and apply revenue and earnings multiples from the identified set of companies to the reporting unit’s actual and forecasted financial performance to determine the fair value of each reporting unit. We evaluate the reasonableness of the fair value calculations of our reporting units by reconciling the total of the fair values of all of our reporting units to our total market capitalization, and adjusting for an appropriate control premium. In addition, we made certain judgments in allocating shared assets and liabilities to determine the carrying values for each of our reporting units. Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions. These estimates and assumptions include revenue growth rates and operating margins used to calculate projected future cash flows, risk-adjusted discount rates, future economic and market conditions and determination of appropriate market comparables. We base our fair value estimates on assumptions we believe to be reasonable but that are unpredictable and inherently uncertain. Actual future results may differ from those estimates. In addition, we make certain judgments and assumptions in allocating shared assets and liabilities to determine the carrying values for each of our reporting units. The timing and frequency of our goodwill impairment tests are based on an ongoing assessment of events and circumstances that would indicate a possible impairment. We will continue to monitor our goodwill and intangible assets for impairment and conduct formal tests when impairment indicators are present. Changes in the carrying amount of goodwill by reportable business segment for the six months ended June 30, 2021 were as follows (in thousands): North America EMEA Emerging Markets Total Balance as of December 31, 2020 $ 83,828 $ 28,223 $ 8,538 $ 120,589 Divestiture — (114) — (114) Foreign currency translation 4 (5) 9 8 Balance as of June 30, 2021 $ 83,832 $ 28,104 $ 8,547 $ 120,483 Intangible Assets Subject to Amortization Our intangible assets include amounts recognized in connection with acquisitions, including customer relationships, tradenames, technology and intellectual property. Intangible assets are initially valued at fair market value using generally accepted valuation methods appropriate for the type of intangible asset. Amortization is recognized on a straight-line basis over the estimated useful life of the intangible assets. Intangible assets with definite lives are reviewed for impairment if indicators of impairment arise. Except for goodwill, we do not have any intangible assets with indefinite useful lives. Intangible assets with finite lives are subject to amortization over their estimated useful lives. The primary assets included in this category and their respective balances were as follows (in thousands): Gross Carrying Amount Accumulated Amortization Net Carrying Amount June 30, 2021 Customer relationships $ 9,476 $ (5,191) $ 4,285 Intellectual property and other 3,104 (2,748) 356 $ 12,580 $ (7,939) $ 4,641 December 31, 2020 Customer relationships $ 9,447 $ (4,457) $ 4,990 Intellectual property and other 3,104 (2,438) 666 $ 12,551 $ (6,895) $ 5,656

Debt

Debt Disclosure [Abstract]
Debt	Debt On November 30, 2018, we entered into a Credit Agreement with PNC Bank, National Association, as administrative agent and a syndicate of lenders (the “Credit Agreement”), replacing the prior Credit Agreement with Wells Fargo dated December 21, 2016, as amended on April 28, 2018 and June 29, 2018 (the "Original Credit Agreement"). The Credit Agreement provides for a revolving credit facility, which expires on November 29, 2023, and consists of: a revolving loan facility with a borrowing limit of $200 million, including a $20 million sublimit for foreign borrowings; an accordion feature allowing the Company to request increases in commitments to the credit facility by up to an additional $100 million; a $20 million letter of credit sublimit; and a swingline loan credit sublimit of $20 million. The obligations under the Credit Agreement are guaranteed by certain of the Company's subsidiaries (the "Guarantors"). As collateral security under the Credit Agreement and the guarantees thereof, the Company and the Guarantors have granted to the administrative agent, for the benefit of the lenders, a lien on, and first priority security interest in substantially all of their tangible and intangible assets. The proceeds of the Credit Agreement were used, in part, to repay in full all outstanding borrowings under the Original Credit Agreement, and additional proceeds of the revolving credit facility are expected to be used for working capital and other general corporate purposes of the Company and its subsidiaries, including the issuance of letters of credit and Permitted Acquisitions, as defined. Borrowings under the Credit Agreement may be in the form of Base Rate loans or Euro-Rate loans, at the option of the borrowers, and bear interest at the Base Rate plus 0.25% to 1.25% or the Daily Adjusted London Inter-bank Offered Rate (LIBOR) plus 1.25% to 2.25% respectively. Base Rate loans will bear interest at a fluctuating per annum Base Rate equal to the highest of (i) the Overnight Bank Funding Rate, plus 0.5%, (ii) the Prime Rate, and (iii) the Daily Adjusted LIBOR, plus 100 basis points (1.0%); plus an Applicable Margin. Determination of the Applicable Margin is based on a pricing grid that is generally dependent upon the Company's Leverage Ratio (as defined) as of the end of the fiscal quarter for which consolidated financial statements have been most recently delivered. We may prepay the revolving loan, in whole or in part, at any time without premium or penalty, subject to certain conditions. The Credit Agreement contains customary representations, warranties and affirmative covenants. The Credit Agreement also contains customary negative covenants, subject to negotiated exceptions, including but not limited to: (i) liens, (ii) investments, (iii) indebtedness, (iv) significant corporate changes, including mergers and acquisitions, (v) dispositions, (vi) restricted payments, including stock dividends, and (vii) certain other restrictive agreements. The Credit Agreement also requires the Company to maintain compliance with the following financial covenants; (i) a maximum leverage ratio, and (ii) a minimum interest expense coverage ratio. On May 7, 2020, we entered into an amendment to the Credit Agreement that increases the maximum leverage ratio we are required to maintain from 3.0 to 1.0 to 3.75 to 1.0 for the fiscal quarters ending June 30, 2020, September 30, 2020 and December 31, 2020, and 3.00 to 1.0 for fiscal quarters ending March 31, 2021 and thereafter, and a minimum interest expense coverage ratio of 3.0 to 1.0. The leverage ratio is computed by dividing our Funded Debt by our Consolidated EBITDA, as those terms are defined in the Credit Agreement, for the trailing four fiscal quarters, and the interest coverage ratio is computed by dividing our Consolidated EBITDA by our Consolidated Interest Expense for the trailing four fiscal quarters. As of June 30, 2021, our leverage ratio was 0.3 to 1.0 and our interest expense coverage ratio was 19.5 to 1.0, each of which was in compliance with the Credit Agreement. In addition, the amendment to the Credit Agreement reduced the borrowing limit under the credit facility from $200 million to $140 million. As of June 30, 2021, there were $9.0 million borrowings outstanding and $91.7 million of available borrowings under the revolving loan facility based on our leverage ratio. For the six months ended June 30, 2021 and 2020, the weighted average interest rate on our borrowings was 1.6% and 3.2%, respectively. As of June 30, 2021, the fair value of our borrowings under the Credit Agreement approximated its carrying value as it bears interest at variable rates. There were $0.9 million of unamortized debt issue costs related to the Credit Agreement as of June 30, 2021 which are being amortized to interest expense over the term of the Credit Agreement and are included in Other assets on our consolidated balance sheet.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense was $1.3 million, or an effective income tax rate of 23.0%, for the six months ended June 30, 2021 compared to a benefit of $(1.8) million, or an effective income tax rate of 48.8%, for the six months ended June 30, 2020. The change in the tax rate was primarily due to changes in the jurisdictional mix of earnings and the tax effects of an increase in pre-tax earnings. Income tax expense for the interim quarterly periods is based on an estimated annual effective tax rate which includes the U.S. federal, state and local, and non-U.S. statutory rates, permanent differences, and other items that may have an impact on income tax expense. On March 27, 2020, Congress enacted the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") to provide certain relief as a result of the COVID-19 pandemic. The CARES Act, among other things, includes various income and payroll tax provisions, as well as provisions relating to net operating loss carryback periods, alternative minimum tax credit refunds, and modification to the net interest deduction limits. Tax payment deferrals provided for under the CARES Act resulted in liabilities for deferred payroll tax payments and other deferred tax payments under other government relief programs in different regions of the world where we operate, totaled $8.0 million as of June 30, 2021, of which approximately $4.8 million is included in accounts payable and accrued expenses and $3.2 million is in other noncurrent liabilities. We continue to monitor any effects that may result from the CARES Act. On March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 into law to enact and extend certain tax relief programs as a result of the COVID-19 pandemic. The Act does not contain provisions that have a material impact on income tax expense and the effective tax rate. An uncertain tax position taken or expected to be taken in a tax return is recognized in the financial statements when it is more likely than not (i.e., a likelihood of more than fifty percent) that the position would be sustained upon examination by tax authorities that have full knowledge of all relevant information. A recognized tax position is then measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Interest and penalties related to income taxes are accounted for as income tax expense. As of June 30, 2021, we had no uncertain tax positions reflected on our condensed consolidated balance sheet. The Company files income tax returns in U.S. federal, state and local jurisdictions, and various non-U.S. jurisdictions, and is subject to audit by tax authorities in those jurisdictions. Tax years 2017 through 2020 remain open to examination by these tax jurisdictions, and earlier years remain open to examination in certain of these jurisdictions which have longer statutes of limitations.

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring During the fourth quarter of 2020, we initiated a review of restructuring and transition activities to improve the efficiency of our general and administrative support functions. As part of these activities, we employed a consultant to perform a review and assessment to determine efficiency opportunities. During the first half of 2021, we executed various activities to improve our general and administrative functions and as a result recorded $0.6 million in consulting cost during the three months ended June 30, 2021, and $1.2 million for the six months ended June 30, 2021. As a result of this review, we incurred $0.3 million in severance costs related to personnel reductions in our general and administrative support functions during the three months ended June 30, 2021, which were mostly paid during the same period. In addition, during the three months ended June 30, 2021, we incurred a $0.9 million impairment cost as a result of the closure of certain operations in the United Kingdom. During the first quarter of 2021, we permanently closed our body shop operations in Thailand and as result incurred a $0.1 million restructuring cost related to the loss on the sale of inventory associated with the business. These costs are included in restructuring charges on the consolidated statements of operations.

Leases

Leases [Abstract]
Leases	Leases We determine at its inception whether an arrangement that provides us control over the use of an asset is a lease. We recognize at lease commencement a right-of-use (ROU) asset and lease liability based on the present value of the future lease payments over the lease term. We have elected not to recognize a ROU asset and lease liability for leases with terms of 12 months or less. Certain of our leases include options to extend the term of the lease or to terminate the lease prior to the end of the initial term. When it is reasonably certain that we will exercise the option, we include the impact of the option in the lease term for purposes of determining total future lease payments. As most of our lease agreements do not explicitly state the discount rate implicit in the lease, we use our incremental borrowing rate on the commencement date to calculate the present value of future payments. Some of our leases include future rent escalations that are based on the Consumer Price Index (CPI) or other similar indices. These future rent escalations are not included in the calculation of the ROU asset and lease liability because they cannot be forecasted at the lease inception date. These are considered variable lease payments and are expensed as incurred. In addition to the present value of the future lease payments, the calculation of the ROU asset also includes any lease pre-payments and initial direct costs of obtaining the lease, such as commissions. In addition to the base rent, real estate leases typically contain provisions for common-area maintenance and other similar services, which are considered non-lease components for accounting purposes. For our real estate leases, we apply a practical expedient to include these non-lease components in calculating the ROU asset and lease liability. For all other types of leases, non-lease components are excluded from our ROU assets and lease liabilities and expensed as incurred. We have operating leases for office facilities, vehicles and office equipment. We do not have any material finance leases. Lease expense is included in Cost of Revenue and General & Administrative Expenses on the condensed consolidated statements of operations, and is recorded net of immaterial sublease income. The components of lease expense were as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Operating lease cost $ 1,683 $ 2,355 $ 3,477 $ 4,684 Short-term lease cost 53 102 133 460 Total lease costs $ 1,736 $ 2,457 $ 3,610 $ 5,144 Supplemental information related to leases was as follows (dollars in thousands): June 30, 2021 December 31, 2020 Operating lease right-of-use assets $ 17,752 $ 20,862 Current portion of operating lease liabilities $ 5,382 $ 5,523 Non-current portion of operating lease liabilities 13,878 16,260 Total operating lease liabilities $ 19,260 $ 21,783 Cash paid for amounts included in the measurement of operating lease liabilities $ 3,476 $ 11,188 Right-of-use assets obtained in exchange for operating lease liabilities $ 1,566 $ 4,523 Weighted-average remaining lease term for operating leases (years) 4.8 years 5.6 years Weighted-average discount rate for operating leases 3.4 % 3.8 % The following is a reconciliation of future undiscounted cash flows to the operating lease liabilities on our condensed consolidated balance sheet as of June 30, 2021 (in thousands): Year ended December 31, 2021 (excluding the six months ended June 30, 2021) $ 3,087 2022 5,189 2023 4,011 2024 3,309 2025 2,844 Thereafter 2,713 Total future lease payments 21,153 Less: imputed interest (1,893) Present value of future lease payments 19,260 Less: current portion of lease liabilities (5,382) Long-term lease liabilities $ 13,878 During the second quarter of 2021, we disposed of $1.1 million of operating lease right-of-use assets and of $1.2 million of operating lease liabilities in connection with the sale of a United Kingdom operation, respectively.

Segment Reporting [Abstract]
Business Segments	Business SegmentsEffective July 1, 2020, we began managing our business under a new organizational structure on a regional basis through our three geographic markets, North America, EMEA and Emerging Markets. These became our reportable segments in the third quarter of 2020. Effective January 1, 2021 as a result of a change in management, we transferred one of our businesses from our North America segment to our EMEA segment. In addition, we realigned some of our businesses between our North America OPS and North America TPS solutions to more accurately align with their focus industries. We have reclassified the segment financial information herein for the prior year periods to reflect the changes in our segment reporting and conform to the current year's presentation. The reorganization was done to achieve the following: • Unlock the potential of organic growth to achieve better business results for our clients and the Company. • Simplify the matrix and empower rapid local decision making in service of our clients. • Leverage global practice systems, processes, and intellectual property while enabling regional authority to better align and deliver to local client needs. • Enable efficient use of our corporate infrastructure with regional resources. Across our regional operating structure, the Company provides Workforce Transformation Services categorized into three primary solution sets: • Organizational Performance Solutions (OPS) - focus is on managed learning services, digital learning strategies and content development, business consulting, and leadership development solutions • Technical Performance Solutions (TPS) - focus is on engineering and technical services, enterprise technology adoption and Human Capital Management (HCM) implementation services. • Automotive Performance Solutions (APS) - provides sales enablement solutions, including custom product sales training and other customer loyalty and marketing related services. We have also identified four focus industries to deliver these services which include Automotive, Financial Services, Defense and Aerospace and Technology. We do not allocate the following items to the segments: general & administrative expenses, sales & marketing expenses, restructuring charges, gain on change in fair value of contingent consideration, gain on sale of business, interest expense, other income (expense), and income tax expense (benefit). The following table sets forth the revenue and operating results attributable to each reportable segment and includes a reconciliation of segment revenue to consolidated revenue and operating results to consolidated income before income tax expense (in thousands): Three Months Ended Six Months Ended 2021 2020 2021 2020 Revenue: North America $ 82,999 $ 72,913 $ 155,328 $ 157,849 EMEA 31,831 23,680 61,804 55,578 Emerging Markets 13,952 9,551 26,201 20,998 $ 128,782 $ 106,144 $ 243,333 $ 234,425 Gross profit: North America $ 16,676 $ 13,527 $ 31,169 $ 26,585 EMEA 4,993 1,393 10,043 5,169 Emerging Markets 2,159 977 4,057 1,757 Total gross profit 23,828 15,897 45,269 33,511 General and administrative expenses 15,442 14,180 30,278 31,464 Sales and marketing expenses 2,562 1,857 5,030 3,696 Restructuring charges 1,763 855 2,462 855 Loss on change in fair value of contingent consideration — — 269 — Gain (loss) on sale of business (377) — (377) 1,064 Operating income (loss) 3,684 (995) 6,853 (1,440) Interest expense 197 607 378 1,585 Other expense 196 189 1,019 689 Income (loss) before income tax expense (benefit) $ 3,291 $ (1,791) $ 5,456 $ (3,714) Revenue by Category The following series of tables presents our revenue disaggregated by various categories (dollars in thousands).

Commitments and Contingencies Disclosure [Abstract]
Contingencies	ContingenciesOn July 14, 2021, the Company’s management was notified by the UK Health and Safety Executive (HSE) of possible violations of workplace safety rules by a U.K. subsidiary of GP Strategies, related to workplace injuries suffered in 2019 by an individual working at a site at which the Company was the principal contractor. The HSE has indicated that certain charges are under consideration, although a decision on whether to prosecute has not been made. The Company is working with counsel to respond to the HSE; however, counsel advises that it is likely that charges will be filed. Legal costs will be recognized as incurred. If charges are filed, the burden would be upon the Company to establish compliance with applicable rules. In the event the Company is determined to have violated applicable laws, statutory penalties will be imposed by the court. The Company anticipates that such penalties, if assessed, are unlikely to exceed $1.25 million. Based on the present status of these matters, management believes the range of reasonably possible losses to be $0 to $1.25 million.

Subsequent Event	Subsequent Event On July 15, 2021, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Learning Technologies Group plc, a public limited company incorporated in England and Wales (“LTG”), Learning Technologies Acquisition Corporation, a Delaware corporation and a direct wholly owned subsidiary of LTG (“US Holdco”), and Gravity Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of US Holdco (“Merger Sub”). The Merger Agreement provides, subject to its terms and conditions, for the acquisition of the Company by LTG at a price of $20.85 in cash for each share of the Company’s common stock (each, a “Share”), without interest thereon and subject to deduction for any required withholding tax (the “Merger Consideration”), through the merger of Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned, indirect subsidiary of LTG (the “Surviving Corporation”). Pursuant to the Merger Agreement, at the effective time of the Merger (the “Effective Time”): • each Share that is issued and outstanding immediately prior to the Effective Time (other than (i) Shares held in the treasury of the Company or owned by the Company, any subsidiary of the Company, LTG, US Holdco, Merger Sub or any other subsidiary of LTG immediately prior to the Effective Time, all of which will be canceled, and (ii) Shares held by stockholders who do not vote in favor of the Merger and who properly exercise their appraisal rights under, and comply in all respects with applicable provisions of, Delaware law) will be automatically cancelled and converted into the right to receive the Merger Consideration; • each restricted stock unit granted by the Company that is subject only to time-based vesting conditions and is outstanding and unvested at the Effective Time will automatically be cancelled and converted into the right to receive from the Surviving Corporation an amount of cash equal to the product of (a) the number of Shares then underlying such restricted stock unit, multiplied by (b) the Merger Consideration; and • each restricted stock unit granted by the Company that is subject to performance-based vesting conditions and is outstanding and unvested at the Effective Time will automatically be cancelled and converted into the right to receive from the Surviving Corporation an amount of cash equal to the product of (a) the number of Shares that vest upon a “Sale of the Company” (as defined in the GP Strategies Corporation 2021 Long-Term Incentive Program) pursuant to the terms of the grant of such restricted stock unit, multiplied by (b) the Merger Consideration. • Pursuant to the Merger Agreement, the GP Strategies Corporation 2011 Stock Incentive Plan will be terminated immediately prior the Effective Time, and participants in the GP Strategies Corporation 2011 Stock Incentive Plan will not have any rights thereunder following the Effective Time, except for the right to receive the payments described above. Completion of the Merger is subject to customary closing conditions, including (i) adoption of the Merger Agreement by the Company’s stockholders (the “Stockholder Approval”), (ii) the absence of governmental orders, stays, decrees, judgments or injunctions, and of statutes, rules or regulations, prohibiting the Merger, (iii) the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and (iv) clearance of the Merger by the Committee on Foreign Investment in the United States. In addition, the obligation of each of the Company and LTG to consummate the Merger is conditioned upon, among other things, the accuracy of the representations and warranties of the other (subject to certain materiality exceptions), and material compliance by the other with its covenants under the Merger Agreement. LTG’s obligation to consummate the Merger is also conditioned upon there not occurring after the date of the Merger Agreement any effect, development, circumstance or change that has, or would reasonably be expected to have, a “Company Material Adverse Effect” (as defined in the Merger Agreement) and upon the admission of the new ordinary shares of LTG to be issued in connection with the Share Issue (as hereinafter defined) to trading on the Alternative Investment Market operated by the London Stock Exchange. The Merger Agreement contains representations and warranties and covenants of the parties customary for a transaction of this nature. Until the earlier of the termination of the Merger Agreement and the Effective Time, the Company has agreed to operate its business in the ordinary course of business and has agreed to certain other operating covenants and to not take certain specified actions prior to the consummation of the Merger, as set forth more fully in the Merger Agreement. The Company has also agreed to convene and hold a meeting of its stockholders for the purpose of obtaining the Stockholder Approval. In addition, the Merger Agreement requires that, subject to certain exceptions, the Board of Directors (the “Board”) recommend that the Company’s stockholders adopt the Merger Agreement. The Merger Agreement contains certain termination rights for the Company and LTG, including, among others, the right of (i) the Company to terminate the Merger Agreement prior to receipt of the Stockholder Approval, if the Company receives an alternative acquisition proposal that constitutes a “Superior Proposal” (as defined in the Merger Agreement), the Company complies with it covenants in the Merger Agreement relating to such proposal, and, substantially concurrently with termination, the Company pays a termination fee to LTG and enters into a definitive agreement to consummate such proposal and (ii) LTG to terminate the Merger Agreement if the Board changes its recommendation with respect to the Merger Agreement. The Merger Agreement also provides that under specified circumstances, the Company may be required to pay LTG a termination fee of $12,000,000 or reimburse LTG for its expenses incurred in connection with the merger agreement and the merger up to a maximum of $1,200,000, or LTG may be obligated to pay GP Strategies a termination fee of $12,000,000 plus reimbursement of GP Strategies’ expenses incurred during fiscal year 2021 in connection with the merger agreement, up to $5,000,000 (or, if lower, the difference of 1% of LTG’s market capitalization as of the date of termination minus $12,000,000).

Recent Accounting Standards (Po

Recent Accounting Standards (Policy)	6 Months Ended

Accounting Standards Update and Change in Accounting Principle [Abstract]
Use of Estimates and Assumptions	The preparation of financial statements in conformity with U.S. GAAP requires us to employ estimates and make     assumptions that affect the reported amounts of certain assets and liabilities, the revenues and expenses reported for the periods covered by the accompanying consolidated financial statements, and certain amounts disclosed in these Notes to the condensed consolidated financial statements. Although such estimates and assumptions are based on management’s most recent assessment of the underlying facts and circumstances utilizing the most current information available and past experience including considerations for potential impacts of the coronavirus (COVID-19) pandemic, actual results could differ significantly from those estimates and assumptions. Our estimates, judgments, and assumptions are evaluated periodically and adjusted accordingly.
Recently Adopted Accounting Standards	In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12, Simplifying the Accounting for Income Taxes . The guidance issued in this update simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in Accounting Standards Codification (ASC) 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition for deferred tax liabilities for outside basis differences. ASU 2019-12 also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. We adopted the standard on January 1, 2021. The new standard did not impact our financial statements. For a discussion of other accounting standards that have been issued by the FASB but are not yet effective, refer to the Recent Accounting Standards section in our Annual Report on Form 10-K for the year ended December 31, 2020. These standards are not expected to have a material impact on our results of operations, financial condition or cash flows.
