Disclosure of Compensation Related Costs, Share-based Payments [Text Block] | NOTE 9 - STOCK COMPENSATION PLANS In June 2009, the Company's stockholders approved a new 2009 Equity Incentive Plan (the “Equity Plan,” or the “Plan”) that provides for the issuance of up to 480,000 shares of common stock. The Equity Plan provides for grants of non-statutory options, incentive stock options, restricted stock awards, performance shares, performance units, restricted stock units and other stock-based awards, in order to enhance the ability of ENGlobal to motivate current employees, to attract employees of outstanding ability and to provide for grants to be made to non-employee directors. Grants to employees will generally vest over a four-year period, one-fourth at December 31 of each year until they are fully vested. Grants to non-employee directors will vest quarterly over a one-year period coinciding with their service term. On April 26, 2012, the Board approved, and the stockholders subsequently approved, an amendment to the Plan to increase the number of shares available for issuance under the Plan by 500,000 from 480,000 to 980,000. On October 20, 2013 the Board approved, and the stockholders subsequently approved, an amendment to the Plan to increase the number of shares available for issuance under the Plan by 850,000 from 980,000 to 1,830,000.

For each series, the exercise price is the weighted average exercise price of the series. We recognize stock compensation expense relating to share-based payments in net income using the fair-value measurement method. Under the fair value method, the estimated fair value of awards is charged to expense over the requisite service period, which is generally the vesting period. We estimate the volatility of our stock price by using historical volatility looking back 156 weeks. The expected term of options granted has been derived from the simplified method, due to changes in vesting terms and contractual lives of current options compared to our historical grants. We base the estimate of the risk-free interest rate on the United States Treasury zero-coupon yield curve in effect at the time of grant. We have never paid cash dividends and do not currently intend to pay cash dividends; accordingly, we have assumed a 0% dividend yield.
