Cathie Black isn't the only person announcing a departure.
New York State Education Commissioner David Steiner has announced that he's stepping down, after a two-year stint. He's expected to leave by July.
In a statement, Merryl Tisch, Chancellor of the State Board of Regents, called Steiner one of "America's leading education reform visionaries." She said he's considering several offers for a new job, and made the announcement now because of leaks in the news that he was looking around.
Tisch also praised Steiner's work leading the state's successful $700 million Race to the Top application, and his work on curriculum reform and raising standards.
