Our mission

Our Story

Built in 1925, Simon Gratz has a rich history filled with iconic leaders and alumni. The school’s namesake, Simon Gratz, gave much to civic life in Philadelphia serving on the Philadelphia Board of Education, where he contributed to the tremendous growth of public education.

Gratz is also the home of notable educator, Dr. Marcus Foster. Dr. Foster served as the principal of Gratz from 1966-1969 before becoming the first Black Superintendent of a large city school district in Oakland, California. Gratz’s athletic field was named in his memory to honor the positive contributions he made to education that are ongoing today.

Originally a public school directly operated by the School District of Philadelphia, Gratz has been operated as a charter school by Mastery Charter since September 2011.
