The Washington Post Company announced on Tuesday that the chief executive officer and chief financial officer of its Kaplan Higher Education division, and the president of Kaplan Higher Education Campuses, are stepping down. The CEO, Jeffrey Conlon, and the president, Beth Hollenberg, are exploring other positions at Kaplan, while the CFO, Lionel Lenz, is not. The shake-up follows weak financial performance at Kaplan, which runs career-oriented colleges as well as Kaplan University and which provides most of the newspaper company’s revenue. Kaplan has recently faced slowing enrollments and increased regulatory pressure from the Education Department. It has also come under scrutiny by several states on accusations of spurious job-placement and graduation rates and overly aggressive recruiting tactics.
