Legal and Regulatory Matters	Dec. 31, 2020
Commitments and Contingencies Disclosure [Abstract]
Legal and Regulatory Matters	Legal and Regulatory Matters Laureate is subject to legal proceedings arising in the ordinary course of business. In management's opinion, we have adequate legal defenses, insurance coverage, and/or accrued liabilities with respect to the eventuality of these actions. Management believes that any settlement would not have a material impact on Laureate's financial position, results of operations, or cash flows. Our institutions are subject to uncertain and varying laws and regulations, and any changes to these laws or regulations or their application to us may materially adversely affect our business, financial condition and results of operations. Continuing Operations Mexican Regulation– COVID-19 Update Administrative activities have resumed at half of our campuses. Face-to-face educational activities will not be permitted to resume at any campus until the region (municipality or state) in which it is located is assigned a green color code under the country’s color-coded sanitary alert system, which is updated on a biweekly basis. Peruvian Regulation– COVID-19 Update Peru’s national sanitary emergency has been extended until March 2021. In addition, due to the second wave of COVID-19, effective from January 31 until February 28, 2021, Peru entered into a region-by-region confinement plan, which includes a total curfew of vehicles and individuals in the whole department of Lima, among others. The economic reactivation plan has been suspended for many activities (mostly malls and restaurants presential attention) during the confinement period, including presential practices classes and some administrative tasks. The government has announced that face-to-face classes may resume this year, initially semi-presential; however, the actual resumption of classes will depend upon COVID-19 infection rates at such time. Discontinued Operations Brazilian Regulation We operate 10 post-secondary education institutions in Brazil. The responsibility of the federal government in regulating, monitoring and evaluating higher education institutions and undergraduate programs is exercised by the Brazilian Ministry of Education (the MEC), along with a number of related federal agencies and related offices. The MEC is the highest authority of the higher education system in Brazil and has the power to issue implementing rules, (regulations, notices, and technical advisories governing the conduct of higher education), as well as to regulate and monitor the higher education segment, including aspects like adherence by higher education institutions (HEIs) to the rules for federal education programs like Prouni and the Fundo de Financiamento Estudantil (the FIES program, or FIES), through one or more of which all of our institutions enroll students. Additionally, Brazilian law requires that almost all change-of-control transactions by Laureate receive the prior approval of the Brazilian antitrust authority, the Conselho Administrativo de Defesa Economico (CADE). As noted, Laureate’s institutions in Brazil participate in the FIES program, which is a federal program established to provide financing to students enrolled in courses in private institutions of higher education that have achieved a minimum satisfactory evaluation according to the National Higher Education Evaluation System (SINAES) and receive a grade of 3 or higher out of 5 on the National Examination of Student Performance (ENADE). Under this basic structure, FIES targets both of the government’s education policy goals: increased access and improved academic quality outcomes. As of December 31, 2020, approximately 4% of our students in Brazil participated in FIES, representing approximately 8.5% of our 2020 Brazil revenues. As of December 31, 2019, approximately 7% of our total students in Brazil participated in FIES, representing approximately 13% of our 2019 Brazil revenues. All of our Brazil HEIs adhere to Prouni, a federal program of tax benefits designed to increase higher education participation rates by making college more affordable. Prouni provides private HEIs with an exemption from certain federal taxes in exchange for granting partial and full scholarships to low-income students enrolled in traditional and technology undergraduate programs. HEIs may join Prouni by signing a term of membership valid for ten years and renewable for the same period. This term of membership shall include the number of scholarships to be offered in each program, unit and class, and a percentage of scholarships for degree programs to be given to indigenous and Afro-Brazilians. To join Prouni, an educational institution must maintain a certain relationship between the number of scholarships granted and the number of regular paying students. The relationship between the number of scholarships and regular paying students is tested annually. If this relationship is not observed during a given academic year due to the departure of students, the institution must adjust the number of scholarships in a proportional manner the following academic year. For the years ended December 31, 2020, 2019 and 2018, our HEIs granted Prouni scholarships of approximately $75,700, $100,600 and $112,500, respectively, that resulted in tax credits. COVID-19 Update In response to the transition from face-to-face classes to online classes due to the COVID-19 pandemic, legislative assemblies in several Brazilian states passed laws requiring schools to discount tuition. With respect to the states in which we operate, only Rio de Janeiro, Bahia and Paraiba passed such laws. However, because injunctions were granted to suspend the effects of such laws in Rio de Janeiro and Paraiba, mandatory discounts only were applied to classes taken at our Bahia campuses. The constitutionality of the aforementioned laws was challenged both in state courts and the Supreme Court. By the end of 2020, the Supreme Court had ruled on the first round of cases – including the Bahia case –, declaring the mandatory discount laws to be at odds with the Brazilian constitution. The same outcome is expected for the remaining cases. As of August 2020, Provisional Presidential Act n. 934/2020 has been converted to Law n. 14,040. Accordingly, institutions remain authorized to substitute face-to-face classes with remote activities and adjust the academic calendar. By the end of 2020, the National Board of Education had issued an opinion concerning the continuity of remote activities for an additional year. The Ministry of Education, however, has insisted on a gradual return to face-to-face classes, beginning on March 1st for higher education. Nonetheless, this effort will be affected by local sanitary indicators and may effectively be delayed until either a safety standard is sustained or mass vaccination reaches the students’ main age groups. As of now, government measures to resume face-to-face educational activities in Brazil are being implemented on a state-by-state and city-by-city basis. Laboratory and professional practice activities have resumed at the vast majority of our Brazilian campuses. Despite being authorized to gradually return to face-to-face classes in some locations, academic planners still consider a larger contingent of remote activities to be the most suitable option given the current circumstances. United States Postsecondary Education Regulation Walden University, our postsecondary educational institution in the United States, is subject to extensive regulation by federal and state governmental entities as well as accrediting bodies. The U.S. Higher Education Act (HEA), and the regulations promulgated thereunder by the U.S. Department of Education (DOE), subject Walden University to ongoing regulatory review and scrutiny. Walden University must also comply with a myriad of requirements in order to participate in Title IV federal financial aid programs under the HEA (Title IV programs). In particular, to participate in the Title IV programs under currently effective DOE regulations, an institution must be authorized to offer its educational programs by the relevant state agencies in the states in which it is located, accredited by an accrediting agency that is recognized by the DOE, and also certified by the DOE. In determining whether to certify an institution, the DOE closely examines an institution’s administrative and financial capability to administer Title IV program funds. Based on Laureate’s consolidated audited financial statements for its fiscal year ended December 31, 2019, the DOE required us to post a letter of credit of approximately $83,600 (an amount equal to 10% of the Title IV program funds received by Laureate in the most recently completed fiscal year) and remain subject to Heightened Cash Monitoring 1. The DOE also required us to comply with additional notification and reporting requirements. We have provided the DOE with a letter of credit in the amount required, and we are complying with the additional requirements. See Note 11, Commitments and Contingencies, for further description of the outstanding DOE letters of credit as of December 31, 2020 and 2019. In recent years, the DOE has proposed or promulgated a substantial number of new regulations that impact Walden University, including, but not limited to, borrower defense to repayment, state authorization and financial responsibility. Changes in or new interpretations of applicable laws, DOE rules, or regulations could have a material adverse effect on Walden University’s eligibility to participate in the Title IV programs. Department of Justice Voluntary Information Request for Walden University Our institutions are subject to regulatory oversight and from time to time must respond to inquiries about their compliance with the various statutory requirements under which they operate. On September 14, 2020, Walden University received a letter from the Civil Division of the United States Department of Justice (referred to herein as “DOJ”) indicating that the DOJ is examining whether Walden University, in the operation of its Masters of Science in Nursing program (referred to herein as the “Nursing Program”), may have violated the Federal False Claims Act by misrepresenting compliance with its program participation agreement with the DOE, which agreement covers Walden University’s participation in federal student financial aid programs under Title IV of the U.S. Higher Education Act. The letter invites Walden University to provide information regarding a number of specific areas primarily related to the practicum component of its Nursing Program, but it makes no allegations of any misconduct or wrongdoing by Walden University. Further, on November 9, 2020, Walden University received notice from the Higher Learning Commission (“HLC”) that a public “Governmental Investigation” designation would be assigned to Walden University due to the DOJ inquiry and such designation became effective on November 9, 2020. On November 24, 2020, representatives of Walden University met with individuals from the DOJ to present the information requested. While Laureate is cooperating with the DOJ’s request to voluntarily provide information, it cannot predict the timing or outcome of this matter. Laureate accrues for a liability when it is both probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Significant judgment is required in both the determination of probability and the determination as to whether a loss is reasonably estimable. The disclosures, accruals or estimates, if any, resulting from the foregoing analysis are reviewed and adjusted to reflect the effect of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular matter. At this time, Laureate does not believe that this matter will have a material effect on its financial position, results of operations, or cash flows. Further, consistent with the HLC’s policies and procedures, a Governmental Investigation designation by the HLC could delay or prevent the HLC’s approval of a substantive change application to approve the pending sale of Walden University. We continue to evaluate these regulatory developments and the potential impact, if any, on the pending sale of Walden University.
