DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION [Abstract]
Business Activities	*Business Activities*— Lincoln Educational Services Corporation and its subsidiaries (collectively, the “Company”, “we”, “our”, and “us”, as applicable) provide diversified career-oriented postsecondary education to recent high school graduates and working adults. The Company, which currently operates 22 campuses in 12 states, has entered into leases for three new campuses: one in Houston, Texas, which opened in the third quarter of 2025, one in Hicksville, New York, with programs expected to begin by the end of 2026, and one in Rowlett, Texas, a northern suburb of Dallas, where the lease is expected to commence in the fourth quarter of 2025, and programs are expected to begin in the first quarter of 2027. The Company offers programs in skilled trades, automotive, health sciences and information technology. The schools operate under the brands Lincoln Technical Institute, Lincoln College of Technology and Nashville Auto Diesel College. Most of the Company’s campuses serve major metropolitan markets and each typically offers courses in multiple areas of study. Five of the campuses are destination schools, which attract students from across the United States and, in some cases, from abroad. The Company’s other campuses primarily attract students from their local communities and surrounding areas. All of the campuses are nationally accredited and are eligible to participate in federal financial aid programs administered by the U.S. Department of Education (“the DOE”) and applicable state education agencies and accrediting commissions, which allow students to apply for and access federal student loans as well as other forms of financial aid. The Company was incorporated in New Jersey in 2003 as the successor-in-interest to various acquired schools including Lincoln Technical Institute, Inc., which opened its first campus in Newark, New Jersey in 1946.
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 United States Securities and Exchange Commission (“SEC”) and in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements. Certain information and footnote disclosures normally included in annual financial statements have been omitted or condensed pursuant to such regulations. These financial statements, which should be read in conjunction with the December 31, 2024 audited Consolidated Financial Statements and notes thereto and related disclosures of the Company included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (“Form 10-K”), reflect all adjustments, consisting of normal recurring adjustments necessary to present fairly the consolidated financial position, results of operations and cash flows for such periods. The results of operations for the nine months ended September 30, 2025 are not necessarily indicative of the results that may be expected for the full fiscal year ending December 31, 2025. The Company’s business is organized into two reportable business segments: Campus Operations and Transitional. The Campus Operations segment includes campuses that are continuing in operation and contribute to the Company’s core operations and performance. The Transitional segment refers to campuses that have been marked for closure and are currently being taught-out, in addition to campuses that are held-for sale or sold. As of September 30, 2025, no campuses were classified in the Transitional segment. During the prior year, the Company’s Summerlin, Las Vegas campus was classified in the Transitional segment. The sale of the Summerlin campus was consummated on January 1, 2025. We evaluate performance based on operating results. Adjustments to reconcile segment results with consolidated results are included in the caption “Corporate,” which primarily includes unallocated corporate activity. The unaudited Condensed Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. All 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 Condensed 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 used to determine the incremental borrowing rate to calculate lease liabilities and right-of-use (“ROU”) assets, lease term to calculate lease cost, bad debts, impairments, useful lives of fixed assets, income taxes, benefit plans, stock-based compensation, and certain accruals. Actual results could differ from those estimates.
Start-up Costs	Start-up Costs—Costs related to the start of new campuses are expensed as incurred.
New Accounting Pronouncements	New Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (the “FASB”) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which provides updates to qualitative and quantitative reportable segment disclosure requirements, including requiring among other things, enhanced disclosures about significant segment expenses and increased interim disclosures. The amendments in ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company has adopted the new disclosure requirements retrospectively in our Condensed Consolidated Financial Statements. In November 2024, the FASB issued Accounting Standard Update (“ASU”) 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses, which requires additional disclosure of certain amounts included in the expense captions presented on the statement of operations, as well as disclosures about selling expenses. The ASU is effective on a prospective basis, with the option for retrospective application for periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. Early adoption is permitted for annual financial statements that have not yet been issued. The Company is currently evaluating the impact that this ASU will have on our financial statement disclosures. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in this ASU require that public business entities on an annual basis 1) disclose specific categories in the rate reconciliation, and 2) provide additional information for reconciling items that meet a quantitative threshold. The amendments require disclosure about the amount of income taxes paid disaggregated (1) by federal, state and foreign taxes, and (2) by individual jurisdictions in which income taxes paid is equal or greater than 5 percent of total income taxes paid. The amendment also requires entities to disclose income or loss from continuing operations before income tax expense disaggregated between domestic and foreign and income tax expense or benefit from continuing operations disaggregated by federal, state and foreign. For all public business entities, this ASU is effective for annual periods beginning after December 15, 2024; early adoption is permitted. We do not expect this ASU to have a material impact on our Condensed Consolidated Financial Statements. In July 2025, the FASB issued ASU No. 2025‑05, Financial Instruments – Credit Losses (Topic 326‑20): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides a practical expedient that all entities can use when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under ASC 606, Revenue from Contracts with Customers. This practical expedient allows entities to assume that current conditions as of the balance sheet date do not change for the remaining life of the asset in determining credit loss reserve for existing receivables and contract assets. This ASU is effective for annual reporting periods beginning after December 15, 2025 and interim reporting periods within those annual reporting periods with early adoption permitted in both interim and annual reporting periods in which financial statements have not yet been issued. The Company is currently evaluating the impact this ASU will have on our financial statement disclosures. In September 2025, the FASB issued ASU 2025-06, Intangibles Goodwill and Other- Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The ASU amends the internal-use software cost capitalization model by eliminating stage-based rules and introduces new capitalization criteria based on management authorization and the probability of project completion. This ASU also clarifies the treatment of software development uncertainty and incorporates guidance on website development costs. The amendments are effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years. ASU 2025-06 may be applied prospectively, retrospectively or on a modified transition approach with early adoption permitted. We do not expect this ASU to have a material impact on our Condensed Consolidated Financial Statements.
Income Taxes	Income Taxes— The Company accounts for income taxes in accordance with Accounting Standards Codification (“ASC”) Topic 740, Income Taxes (“ASC 740”). This statement requires an asset and a 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 our 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, our 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 considers, 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 our Condensed 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 our income tax provision to vary significantly among financial reporting periods. We recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense. During the nine months ended September 30, 2025 and 2024, we did not record any interest and penalties expense associated with uncertain tax positions, as we did not have any uncertain tax positions. On July 4, 2025, the U.S. enacted legislation which generally extends the tax provisions enacted in 2017 that were set to expire at the end of 2025 and makes other changes to federal tax law for multinational corporations. The Company is currently evaluating the impact of the new legislation but does not expect it to have a material impact on the financial results of operations for the current year.

Disclosure of accounting policy for income taxes, which may include its accounting policies for recognizing and measuring deferred tax assets and liabilities and related valuation allowances, recognizing investment tax credits, operating loss carryforwards, tax credit carryforwards, and other carryforwards, methodologies for determining its effective income tax rate and the characterization of interest and penalties in the financial statements.
