Kaplan was founded in 1938 by Stanley H. Kaplan, who started the business by tutoring students for the New York State Regents Exam in the basement of his parents’ Brooklyn home. He eventually opened locations around the country. In 1984, Kaplan sold the company to The Washington Post Company, which centralized control. The company grew significantly in the 1990s by expanding its business and purchasing other test preparation and educational companies. The company’s leader during this expansion period was Jonathan Grayer.
