Accounting Policies [Abstract]
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards Accounting Standards Update (ASU) No. 2019-12 (ASU 2019-12), Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU 2019-12, which removes certain exceptions for performing intraperiod tax allocations, recognizing deferred taxes for investments, and calculating income taxes in interim periods. The guidance also simplifies the accounting for franchise taxes, transactions that result in a step-up in the tax basis of goodwill, and the effect of enacted changes in tax laws or rates in interim periods. The Company adopted ASU 2019-12 in the first quarter of 2021 and the adoption had no material impact to our Consolidated Financial Statements.
Revenue Recognition	Revenue Recognition Laureate's revenues primarily consist of tuition and educational service revenues. We also generate other revenues from student fees, dormitory/residency fees and other education-related activities. These other revenues are less material to our overall financial results and have a tendency to trend with tuition revenues. Revenues are recognized when control of the promised goods or services is transferred to our customers in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. These revenues are recognized net of scholarships and other discounts, refunds, waivers and the fair value of any guarantees made by Laureate related to student financing programs. Laureate's institutions have various billing and academic cycles. We determine revenue recognition through the five-step model prescribed by ASC Topic 606, Revenue from Contracts with Customers, as follows: •Identification of the contract, or contracts, with a customer; •Identification of the performance obligations in the contract; •Determination of the transaction price; •Allocation of the transaction price to the performance obligations in the contract; and •Recognition of revenue when, or as, we satisfy a performance obligation. We assess collectibility on a portfolio basis prior to recording revenue. Generally, students cannot re-enroll for the next academic session without satisfactory resolution of any past-due amounts. If a student withdraws from an institution, Laureate's obligation to issue a refund depends on the refund policy at that institution and the timing of the student's withdrawal. Generally, our refund obligations are reduced over the course of the academic term. We record refunds as a reduction of deferred revenue as applicable. Contract Balances The timing of billings, cash collections and revenue recognition results in accounts receivable (contract assets) and deferred revenue and student deposits (contract liabilities) on the Consolidated Balance Sheets. We have various billing and academic cycles and recognize student receivables when an academic session begins, although students generally enroll in courses prior to the start of the academic session. Receivables are recognized only to the extent that it is probable that we will collect substantially all of the consideration to which we are entitled in exchange for the goods and services that will be transferred to the student. We receive advance payments or deposits from our students before revenue is recognized, which are recorded as contract liabilities in deferred revenue and student deposits. Payment terms vary by university with some universities requiring payment in advance of the academic session and other universities allowing students to pay in installments over the term of the academic session.
Business and Geographic Segment Information	Laureate’s educational services are offered through two reportable segments: Mexico and Peru. Laureate determines its segments based on information utilized by the chief operating decision maker to allocate resources and assess performance. Our segments generate revenues by providing an education that emphasizes profession-oriented fields of study with undergraduate and graduate degrees in a wide range of disciplines. Our educational offerings are increasingly utilizing online and hybrid (a combination of online and in-classroom) courses and programs to deliver their curriculum. In response to the COVID-19 pandemic, we have temporarily transitioned the educational delivery method at all of our institutions to be online and are leveraging our existing technologies and learning platforms to serve students outside of the traditional classroom setting. The Mexico and Peru markets are characterized by what we believe is a significant imbalance between supply and demand. The demand for higher education is large and growing and is fueled by several demographic and economic factors, including a growing middle class, global growth in services and technology-related industries and recognition of the significant personal and economic benefits gained by graduates of higher education institutions. The target demographics are primarily 18- to 24-year-olds in the countries in which we compete. We compete with other private higher education institutions on the basis of price, educational quality, reputation and location. We believe that we compare favorably with competitors because of our focus on quality, professional-oriented curriculum. There are a number of private and public institutions in both of the countries in which we operate, and it is difficult to predict how the markets will evolve and how many competitors there will be in the future. We expect competition to increase as the Mexican and Peruvian markets mature. Essentially all of our revenues were generated from private pay sources as there are no material government-sponsored loan programs in Mexico or Peru. Specifics related to both of our reportable segments are discussed below. Private education providers in Mexico constitute 35% of the total higher-education market. The private sector plays a meaningful role in higher education, bridging supply and demand imbalances created by a lack of capacity at public universities. Laureate owns two institutions and is present throughout the country with a footprint of over 35 campuses. Each institution in Mexico has a national license. Students in our Mexican institutions typically finance their own education. In Peru, private universities are increasingly providing the capacity to meet growing demand and constitute 72% of the total higher-education market. Laureate owns three institutions in Peru. As discussed in Note 1, Description of Business, and Note 4, Discontinued Operations and Assets Held for Sale, a number of our subsidiaries have met the requirements to be classified as Discontinued Operations. As a result, the Discontinued Operations have been excluded from the segment information for all periods presented. Inter-segment transactions are accounted for in a similar manner as third-party transactions and are eliminated in consolidation. The Corporate amounts presented in the following tables include corporate charges that were not allocated to our reportable segments and adjustments to eliminate inter-segment items. We evaluate segment performance based on Adjusted EBITDA, which is a non-GAAP performance measure defined as Income (loss) from continuing operations before income taxes and equity in net income of affiliates, adding back the following items: Gain (loss) on disposal of subsidiaries, net, Foreign currency exchange (loss) gain, net, Other (expense) income, net, Loss on derivatives, Loss on debt extinguishment, Interest expense, Interest income, Depreciation and amortization expense, Loss on impairment of assets, Share-based compensation expense and expenses related to our Excellence-in-Process (EiP) initiative. EiP is an enterprise-wide initiative to optimize and standardize Laureate’s processes, creating vertical integration of procurement, information technology, finance, accounting and human resources. It included the establishment of regional shared services organizations (SSOs), as well as improvements to the Company's system of internal controls over financial reporting. The EiP initiative also includes other back- and mid-office areas, as well as certain student-facing activities, expenses associated with streamlining the organizational structure, an enterprise-wide program aimed at revenue growth, and certain non-recurring costs incurred in connection with the dispositions described in Note 5, Dispositions. When we review Adjusted EBITDA on a segment basis, we exclude intercompany revenues and expenses related to network fees and royalties between our segments, which eliminate in consolidation. We use total assets as the measure of assets for reportable segments.
Derivative Instruments	In the normal course of business, our operations are exposed to fluctuations in foreign currency values and interest rate changes. We may seek to control a portion of these risks through a risk management program that includes the use of derivative instruments. Prior to their repayment, Laureate’s senior long-term debt arrangements were primarily in USD. Our ability to make debt payments was subject to fluctuations in the value of the USD against foreign currencies, since a majority of our operating cash used to make these payments was generated by subsidiaries with functional currencies other than USD. As part of our overall risk management policies, Laureate has at times entered into foreign currency swap contracts and floating-to-fixed interest rate swap contracts. In addition, we occasionally enter into foreign exchange forward contracts to reduce the impact of other non-functional currency-denominated receivables and payables. We do not enter into speculative or leveraged transactions, nor do we hold or issue derivatives for trading purposes. We generally intend to hold our derivatives until maturity. Laureate reports all derivatives at fair value. These contracts are recognized as either assets or liabilities, depending upon the derivative’s fair value. Gains or losses associated with the change in the fair value of these swaps are recognized in our Consolidated Statements of Operations on a current basis over the term of the contracts, unless designated and effective as a hedge. For swaps that are designated and effective as cash flow hedges, gains or losses associated with the change in fair value of the swaps are recognized in our Consolidated Balance Sheets as a component of AOCI and amortized into earnings as a component of Interest expense over the term of the related hedged items. Upon early termination of an effective interest rate swap designated as a cash flow hedge, unrealized gains or losses are deferred in our Consolidated Balance Sheets as a component of AOCI and are amortized as an adjustment to Interest expense over the period during which the hedged forecasted transaction affects earnings. For derivatives that are both designated and effective as net investment hedges, gains or losses associated with the change in fair value of the derivatives are recognized on our Consolidated Balance Sheets as a component of AOCI.
Earnings (Loss) Per Share	Our common stock has a dual class structure, consisting of Class A common stock and Class B common stock. Other than voting rights, the Class B common stock has the same rights as the Class A common stock, and therefore both are treated as the same class of stock for purposes of the earnings per share calculation. Laureate computes basic earnings per share (EPS) by dividing income available to common shareholders by the weighted average number of common shares outstanding for the reporting period. Diluted EPS reflects the potential dilution that would occur if share-based compensation awards, contingently issuable shares, or convertible securities were exercised or converted into common stock. To calculate the diluted EPS, the basic weighted average number of shares is increased by the dilutive effect of stock options, restricted stock, restricted stock units, and any contingently issuable shares determined using the treasury stock method, and any convertible securities using the if-converted method.
Fair Value Measurement	Fair value is defined as the price that would be received to sell an asset or paid to settle a liability in an orderly transaction between market participants at the measurement date. Accounting standards utilize a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels, which are described below: •Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets; •Level 2 – Observable inputs other than quoted prices that are either directly or indirectly observable for the asset or liability; •Level 3 – Unobservable inputs that are supported by little or no market activity. These levels are not necessarily an indication of the risk of liquidity associated with the financial assets or liabilities disclosed. In instances where the determination of fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety, as required under ASC 820-10, "Fair Value Measurement." Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.
