School History
Our school is the namesake of Zadok Casey, a prominent and active citizen during the settlement of Mt. Vernon. Zadok Casey served as Lt. Governor of Illinois and was a member of Congress for ten years.

Casey Middle School was built on a section of the original Zadok Casey homestead and has graduated thousands since its late fall beginnings in 1937.
 
Over the years, the campus has been maintained and upgraded to provide a safe and comprehensive learning environment. At the start of the 2013-2014 school year, a new sixth grade building was completed and the 1973 Unified Arts Building was renonvated and houses a spacious cafeteria, fitness center, and band classroom. The Science Building, built in 1978, was also renovated and hosts classrooms and administrative offices.
