SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Business Activities	Business Activities – Lincoln Educational Services Corporation and Subsidiaries (the “Company”) is a provider of diversified career-oriented post-secondary education. The Company offers recent high school graduates and working adults career-oriented programs in five areas of study: Automotive Technology, Health Sciences, Skilled Trades, Hospitality Services and Business and Information Technology. The Company currently has 31 campuses and five training sites in 15 states across the United States. For the last several years, the Company and the proprietary school sector has faced various forms of adversity which have contributed to deteriorating earnings growth. Government regulations have negatively impacted earnings by making it more difficult for potential students to obtain loans, which when coupled with the overall economic environment have hindered potential students from enrolling in our schools. In light of these factors, the Company has incurred significant operating losses as a result of lower student population. The Company also experienced a significant decline in market capitalization during the quarter ended September 30, 2014. Despite these events, management believes that its likely sources of cash should be sufficient to fund operations for the next twelve months. The Company's available sources of cash primarily include results of operations, cash and cash equivalents and available borrowings under the revolving line of credit. The Company's revolving credit facility expires in April 2015. To fund the Company's business plans, including any anticipated future losses, purchase commitments, capital expenditures, and principal and interest payments on borrowings, the Company has the ability to leverage up to $ 50 million of its existing properties. In addition, the Company is also continuing to take actions to improve cash flow by aligning its cost structure to its student population. However, if the Company is unable to leverage certain of its properties and improve operating performance, the Company's business plans may be adversely affected and the Company will have to modify its business plans to conserve available cash.
Basis of Presentation	Basis of Presentation – The accompanying unaudited condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission and in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Certain information and footnote disclosures normally included in annual financial statements have been omitted or condensed pursuant to such regulations. These statements, which should be read in conjunction with the December 31, 2013 consolidated financial statements of the Company, reflect all adjustments, consisting of normal recurring adjustments and impairments necessary to present fairly the consolidated financial position, results of operations and cash flows for such periods. The results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2014. The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements – The preparation of financial statements in conformity with GAAP 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 consolidated financial statements and the reported amounts of revenues and expenses during the period. On an ongoing basis, the Company evaluates the estimates and assumptions including those related to revenue recognition, bad debts, fixed assets, goodwill and other intangible assets, stock-based compensation, income taxes, benefit plans and certain accruals and contingencies. Actual results could differ from those estimates.
New Accounting Pronouncements	New Accounting Pronouncements –In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The amendments in this ASU provide guidance on the financial statement presentation of unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this ASU did not materially impact the presentation of the Company’s financial condition, results of operation and disclosures. In April 2014, FASB issued amended guidance on the use and presentation of discontinued operations in an entity's consolidated financial statements. The new guidance restricts the presentation of discontinued operations to business circumstances when the disposal of business operations represents a strategic shift that has or will have a major effect on an entity's operations and financial results. The guidance becomes effective on January 1, 2015. Adoption is on a prospective basis. In May 2014, FASB issued a new standard related to revenue recognition, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The new standard will replace most of the existing revenue recognition standards in GAAP when it becomes effective on January 1, 2017. Early adoption is not permitted. The new standard can be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of the change recognized at the date of the initial application. The Company is assessing the potential impact of the new standard on financial reporting and has not yet selected a transition method.
Stock-Based Compensation	Stock-Based Compensation – The Company measures the value of stock options on the grant date at fair value, using the Black-Scholes option valuation model. The Company amortizes the fair value of stock options, net of estimated forfeitures, utilizing straight-line amortization of compensation expense over the requisite service period of the grant. The Company measures the value of service and performance-based restricted stock on the fair value of a share of common stock on the date of the grant. The Company amortizes the fair value of service-based restricted stock utilizing straight-line amortization of compensation expense over the requisite service period of the grant. The Company amortizes the fair value of the performance-based restricted stock based on the determination of the probable outcome of the performance condition. If the performance condition is expected to be met, then the Company amortizes the fair value of the number of shares expected to vest utilizing straight-line basis over the requisite performance period of the grant. However, if the associated performance condition is not expected to be met, then the Company does not recognize the stock-based compensation expense.
Income Taxes	Income Taxes – The Company accounts for income taxes in accordance with FASB ASC Topic 740, “Income Taxes” (“ASC 740”). This statement requires an asset and liability approach for measuring deferred taxes based on temporary differences between the financial statement and tax bases of assets and liabilities existing at each balance sheet date using enacted tax rates for years in which taxes are expected to be paid or recovered. In accordance with ASC 740, the Company assesses its deferred tax asset to determine whether all or any portion of the asset is more likely than not unrealizable. A valuation allowance is required to be established or maintained when, based on currently available information, it is more likely than not that all or a portion of a deferred tax asset will not be realized. In accordance with ASC 740, the Company’s assessment considers whether there has been sufficient income in recent years and whether sufficient income is expected in future years in order to utilize the deferred tax asset. In evaluating the realizability of deferred income tax assets, the Company considered, among other things, historical levels of income, expected future income, the expected timing of the reversals of existing temporary reporting differences, and the expected impact of tax planning strategies that may be implemented to prevent the potential loss of future income tax benefits. Significant judgment is required in determining the future tax consequences of events that have been recognized in the Company’s consolidated financial statements and/or tax returns. Differences between anticipated and actual outcomes of these future tax consequences could have a material impact on the Company’s consolidated financial position or results of operations. Changes in, among other things, income tax legislation, statutory income tax rates, or future income levels could materially impact the Company’s valuation of income tax assets and liabilities and could cause the Company’s income tax provision to vary significantly among financial reporting periods. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. During the three and nine months ended September 30, 2014 and 2013, the interest and penalties expense associated with uncertain tax positions did not materially impact the Company’s results of operations or financial position.
Reclassifications	Reclassifications – During the nine months ended September 30, 2014, the Company reclassified amounts reflected in the 2013 consolidated balance sheet, to conform to the revised 2014 classification. For the year ended December 31, 2013, the Company had reported $89.7 million in long-term debt and lease obligations on the consolidated balance sheet. The Company reclassified $54.5 million of long-term credit agreement, $25.5 million of long-term capital lease obligations, and $9.7 million of long-term finance obligations into their own liability classifications on the consolidated balance sheet.
