Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Presentation | Note 1: Basis of Presentation Exponent, Inc. (referred to as the “Company” or “Exponent”) is an engineering and scientific consulting firm that provides solutions to complex problems. The Company operates on a 52-53 week fiscal year ending on the Friday closest to the last day of December. The accompanying unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X promulgated by the Securities and Exchange Commission. Accordingly, they do not contain all the information and notes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments which are necessary for the fair presentation of the condensed consolidated financial statements have been included and all such adjustments are of a normal and recurring nature. The operating results for the three and six months ended June 29, 2018 are not necessarily representative of the results of future quarterly or annual periods. The following information should be read in conjunction with the audited consolidated financial statements and accompanying notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 29, 2017, which was filed with the U.S. Securities and Exchange Commission on February 23, 2018. The unaudited condensed consolidated financial statements include the accounts of Exponent, Inc. and its subsidiaries, which are all wholly owned. All intercompany accounts and transactions have been eliminated in consolidation. Stock Split. Dividend.

The Company expects to continue paying quarterly dividends in the future, subject to declaration by the Company’s Board of Directors. Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Items subject to such estimates and assumptions include accounting for revenue recognition and estimating the allowance for contract losses and doubtful accounts. Actual results could differ from those estimates. Recently Adopted Accounting Pronouncements Revenue from Contracts with Customers Recent Accounting Pronouncements Not Yet Effective Leases |

Revenue Recognition [Abstract] | |
Revenue Recognition | Note 2: Revenue Recognition Substantially all of the Company’s engagements are performed under time and material or fixed-price arrangements. For time and materials contracts, the Company utilizes the practical expedient under the ASU which states, if an entity has a right to consideration from a customer in an amount that corresponds directly with the value of the entity’s performance completed to date (for example, a service contract in which an entity bills a fixed amount for each hour of service provided), the entity may recognize revenue in the amount to which the entity has a right to invoice. During the second quarter of fiscal 2018, the Company recognized revenue of $ 79,965,000 84 62,347,000 17,618,000 163,136,000 85 126,948,000 36,188,000 For fixed price contracts, the Company recognizes revenue over time under the ASU because of the continuous transfer of control to the customer. The customer typically controls the work in process as evidenced either by contractual termination clauses or by the Company’s rights to payment for work performed to date to deliver services that do not have an alternative use to the Company. Revenue for fixed price contracts is recognized based on the relationship of incurred labor hours at standard rates to the Company’s estimate of the total labor hours at standard rates it expects to incur over the term of the contract. The Company believes this methodology achieves a reliable measure of the revenue from the consulting services it provides to its customers under fixed-price contracts given the nature of the consulting services the Company provides and the following additional considerations: ⋅ the Company considers labor hours at standard rates and expenses to be incurred when pricing its contracts; ⋅ the Company generally does not incur set up costs on its contracts; ⋅ the Company does not believe that there are reliable milestones to measure progress towards completion; ⋅ if the contract is terminated early, the customer is required to pay the Company for time at standard rates plus materials incurred to date; ⋅ the Company’s contracts do not include award fees or bonuses; ⋅ the Company does not include revenue for unpriced change orders until the customer agrees with the changes; ⋅ historically the Company has not had significant accounts receivable write-offs or cost overruns; and ⋅ its contracts are typically progress billed on a monthly basis. During the second quarter of fiscal 2018, the Company recognized revenue of $ 15,656,000 16 14,733,000 923,000 28,942,000 15 27,179,000 1,763,000 Deferred revenues represent amounts billed to clients in advance of services provided. During the second quarter of fiscal 2018, $ 2,671,000 4,604,000 Reimbursements, including those related to travel and other out-of-pocket expenses, and other similar third party costs such as the cost of materials and certain subcontracts, are included in revenues, and an equivalent amount of reimbursable expenses are included in operating expenses. Any mark-up on reimbursable expenses is included in revenues. The Company reports revenues net of subcontractor fees for certain subcontracts where the Company has determined that it is acting as an agent because its performance obligation is to arrange for the provision of goods or services by another party. The total amount of subcontractor fees not included in revenues because the Company was acting as an agent were $ 5.8 11.4 |

Share-based Compensation [Abstract] | |
Stock-Based Compensation | Note 5: Stock-Based Compensation Restricted Stock Units Restricted stock unit grants are designed to attract and retain employees, and to better align employee interests with those of the Company’s stockholders. For a select group of employees, up to 40 The value of these restricted stock unit awards is determined based on the market price of the Company’s common stock on the date of grant. The value of fully vested restricted stock unit awards issued is recorded as a reduction to accrued bonuses. The portion of bonus expense that the Company expects to settle with fully vested restricted stock unit awards is recorded as stock-based compensation during the period the bonus is earned. The Company recorded stock-based compensation expense associated with accrued bonus awards of $ 2,168,000 2,201,000 4,400,000 4,129,000 59 1,460,000 1,238,000 4,968,000 4,494,000 Stock Options Stock options are granted for terms of ten years and generally vest 25% per year over a four-year period from the grant date. Unvested stock option awards will continue to vest in the case of retirement at 59½ years or older, provided that the holder of each award does all consulting work through the Company and does not become an employee for a past or present client, beneficial party or competitor of the Company. The value of the unvested stock option awards granted is recognized on a straight-line basis over the shorter of the four-year vesting period or the period between the grant date and the date the award recipient turns 59½. If the award recipient is 59½ years or older on the date of grant, the value of the entire award is expensed upon grant. The Company grants options at exercise prices equal to the fair value of the Company’s common stock on the date of grant. The Company recorded stock-based compensation expense associated with stock option grants of $ 116,000 93,000 The Company uses the Black-Scholes option-pricing model to determine the fair value of options granted. The determination of the fair value of stock option awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of complex and subjective variables. These variables include expected stock price volatility over the term of the award, actual and projected employee stock option exercise behaviors, the risk-free interest rate and expected dividends. The Company used historical exercise, forfeiture, and post-vesting expiration data to estimate the expected term of options granted. The historical volatility of the Company’s common stock over a period of time equal to the expected term of the options granted was used to estimate expected volatility. The risk-free interest rate used in the option-pricing model was based on United States Treasury zero-coupon issues with remaining terms similar to the expected term of the options. The dividend yield assumption considers the expectation of continued declaration of dividends, offset by option holders’ dividend equivalent rights. The Company accounts for forfeitures of stock-based awards when they occur. All stock-based payment awards are recognized on a straight-line basis over the requisite service periods of the awards. |
