Steyning Grammar School was founded and endowed as a grammar school in 1614 by William Holland, an Alderman of Chichester. In 1968, it merged with Steyning Secondary Modern School to form the current comprehensive school. The combined school shares two sites in Steyning: Church Street, which houses years 7 and 8, and Shooting Field, which houses years 9-11 and the sixth form college.
