Welcome to the home of the Central Middle School Mustangs! Central Middle School (CMS), located at 828 Chestnut Street, was originally opened on September 30, 1930. Additions were added to the school in 1939, 1941, 1942, and in 1960. Over the last 11 years the school has built a new gym as well modernized the classrooms and Mustang Hall, the school auditorium. Central Middle School serves 640 students in grades 5th – 8th. The staff and parent community work closely together to provide a high quality education with many enrichment opportunities for our students. This is largely due to our strong partnership with the PTA and the SCEF (San Carlos Education Foundation). We are very proud of our school and the wonderful children, staff, and parent community that make it a special place to be.
