Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, our condensed consolidated financial statements do not include all the information and footnotes required by GAAP for complete financial statements. Normal and recurring adjustments considered necessary for a fair statement of the results for the interim periods have been included. Operating results for the nine months ended June 30, 2022 are not necessarily indicative of the results that may be expected for the year ending September 30, 2022. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our 2021 Annual Report on Form 10-K. The unaudited condensed consolidated financial statements include the accounts of Universal Technical Institute, Inc. and our wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Other than described below, there have been no material changes or developments in our significant accounting policies or evaluation of accounting estimates and underlying assumptions or methodologies from those disclosed in Note 2 of our 2021 Annual Report on Form 10-K. New Significant Accounting Policy for Goodwill and Intangible Assets We test goodwill and indefinite-lived intangible assets for impairment annually as of August 1, or more frequently if events and circumstances warrant. Under ASC 350, Intangibles - Goodwill and Other, to evaluate the impairment of goodwill, we first assess qualitative factors, such as deterioration in the operating performance of the acquired business, adverse market conditions, adverse changes in the applicable laws or regulations and a variety of other circumstances, to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. To evaluate the impairment of the indefinite-lived intangible assets, we assess the fair value of the assets to determine whether they were greater or less than the carrying values. If we conclude that it is more likely than not that the fair value is less than the carrying amount based on our qualitative assessment, or that a qualitative assessment should not be performed, we proceed with the quantitative impairment tests to compare the estimated fair value of the reporting unit to the carrying value of its net assets. Determining the fair value of indefinite-lived intangible assets is judgmental in nature and involves the use of significant estimates and assumptions. We believe the most critical assumptions and estimates in determining the estimated fair value of our reporting units include, but are not limited to, future tuition revenues, operating costs, working capital changes, capital expenditures and a discount rate. The assumptions used in determining our expected future cash flows consider various factors such as historical operating trends particularly in student enrollment and pricing and long-term operating strategies and initiatives. There were no indicators of impairment for our goodwill or indefinite-lived intangible assets as of June 30, 2022. We also have definite-lived intangible assets, which primarily consist of purchased intangibles and capitalized curriculum development costs. The definite-lived intangible assets are recognized at cost less accumulated amortization. Amortization is computed using the straight-line method based on estimated useful lives of the related assets. See Note 8 and Note 9 for additional details on our goodwill and intangible assets. Reclassifications Due to the acquisition of MIAT on November 1, 2021, which is described in further detail in Note 4, we added a new line to the condensed consolidated balance sheet: “Intangible Assets.” We have presented the intangible assets arising from the MIAT acquisition as well as the previously recorded intangible assets in this line. As of September 30, 2021, $0.1 million of intangible assets was reclassified from “Other assets” to “Intangible assets” on the condensed consolidated balance sheet for comparable presentation.
