– Educational content maker McGraw-Hill Education plans to go public.

It filed for an IPO that was valued at up to $100 million, according to a form filed Friday with the Securities and Exchange Commission.

The New York-based company says its programs are used by 250,000 higher education instructors and in 13,000 kindergarten to 12th-grade school districts. It also makes products for companies, academic institutions, libraries and hospitals.

Apollo Global Management bought McGraw-Hill Education from what was then the McGraw-Hill Cos. The $2.4 billion deal closed in March 2013, and the rest of McGraw-Hill is now McGraw Hill Financial Inc., a company focused on serving the global capital and commodity markets.
