Adtalem Global Education Inc., formerly DeVry Education Group, is a United States corporation based in Downers Grove, Illinois, that operates several for-profit higher education institutions, including Advanced Academics, Becker Professional Education, Carrington College, Chamberlain College of Nursing, DeVry Brasil, DeVry University, EduPristine, American University of the Caribbean, and Ross University Schools of Medicine and Veterinary Medicine.

Adtalem Global Education was a successor to two separate entities: DeVry Institutes and the Keller-Taylor Corporation (d/b/a Keller Graduate School of Management). DeVry Technical Institute was acquired by the Bell & Howell company in 1966, and became part of its Education Group division. The school was renamed to DeVry Institute of Technology in 1968. In 1984, the education division was renamed DeVry, Inc. ("Old DeVry"), and became publicly traded on the American Stock Exchange.

The Keller-Taylor Corporation was formed in 1973 by Dennis Keller and Ronald Taylor. Keller-Taylor was the holding company of CBA Institute in Chicago, which later became Keller Graduate School of Management. In 1987 Keller-Taylor acquired the DeVry Institutes from Bell & Howell and merged with Keller Graduate School of Management. The holding company's name changed to DeVry, Inc.

In 1991, DeVry became the first publicly traded education provider with an initial public offering on the NASDAQ stock exchange. In 1995, DeVry moved to the New York Stock Exchange (NYSE) and began trading under the symbol DV (NYSE: DV). In 2017, the company changed its ticker symbol to ATGE (NYSE: ATGE).

In 1996 DeVry acquired Becker CPA Review, now Becker Professional Education. In 2002 DeVry Institute of Technology and Keller Graduate School of Management became DeVry University. The company diversified into healthcare in 2003 with the acquisition of Ross University and added Chamberlain College of Nursing (then Deaconess College of Nursing) in 2005.

In 2007, DeVry expanded its reach into online education with the addition of Advanced Academics, an online secondary education that partners with schools and school districts across the United States. Carrington College, formerly known as Apollo College and Western Career College, joined DeVry in 2008. In 2009, DeVry acquired a majority stake in Fanor, now known as DeVry Brasil, a provider of post-secondary education with campuses located in northeastern Brazil. In June 2009, Standard and Poor's added Devry Inc. to its index of stocks, replacing newly-bankrupt General Motors.

In 2011, DeVry continued its international reach with the acquisition of ATC International (a subsidiary of Becker Professional Education), which provides professional finance and accounting training in Central and Eastern Europe as well as Central Asia; and American University of the Caribbean, a medical school located in St. Maarten.

In November 2013, DeVry Inc. was renamed to DeVry Education Group.

Daniel Hamburger resigned in 2016 as CEO of DeVry with a payout of 5.3 million dollars. Eight-year board member, Lisa Wardell was appointed president and CEO of DeVry Education Group. Wardell is the only female African-American CEO in the Fortune 1000.

In 2017, DeVry Education rebranded to Adtalem Global Education.

DeVry subsidiaries include Advanced Academics, American University of the Caribbean School of Medicine, Becker Professional Education, ATC International, the Carrington Colleges Group, Chamberlain College of Nursing, DeVry Brasil, DeVry University and its Keller Graduate School of Management, Ross University School of Medicine and Ross University School of Veterinary Medicine.

DeVry Brazil's enrollment in 2016 was 79,280 students.

The for-profit education industry has been the subject of hearings by the United States Senate Committee on Health, Education, Labor, and Pensions. Specifically with regard to DeVry Inc., the Committee found that over half of the students who enrolled at DeVry in 2008-2009 withdrew by mid-2010. DeVry spends more on marketing than on student instruction. Approximately 80% of DeVry's revenue is Federal education funds.

As of 2013, DeVry Inc. is under investigation by the Attorneys General of the states of Illinois and Massachusetts.

A lawsuit has been filed against DeVry alleging deceptive recruiting practices in violation of federal law.

In January 2016, The Federal Trade Commission filed a lawsuit against DeVry Education Group alleging false or misleading advertising. A class action lawsuit was also filed against DeVry Group in US District Court, Northern District of California claiming breaches of contract, good faith and fair dealing, violations of the California Unfair Trade Practices Act, the California False Advertising Act and the California Consumer Legal Remedies Act, and negligent misrepresentations. A confidential settlement was reached.

In May 2016, a shareholder class action lawsuit was filed against DeVry Group, in the US District Court, Northern District of Illinois. The plaintiffs claimed that defendants made false or misleading statements regarding DeVry University’s graduate employment rate and the earnings of DeVry University graduates relative to the graduates of other universities and colleges.

In June 2016, T’Lani Robinson and Robby Brown filed an arbitration demand with the American Arbitration Association, seeking relief for breach of contract, negligence, violation of the Illinois Uniform Deceptive Trade Practices Act, conversion, and unjust enrichment.
