Grissom Middle School was built in 1968 and serves students from Elm Road, Madison, Moran and Meadow’s Edge Elementary schools.  


Academic Programs

Grissom offers a unique instructional program that provides for the interdisciplinary teaming of teachers.  Instruction is provided in the fine arts/practical arts areas as well as in physical education and health.  Band, choir and orchestra experiences are available for all students.  A school-wide enrichment program and an academic competition program provide the opportunity for students to challenge themselves.   An inclusion program addresses students with special learning needs.  A program of focused instruction assures achievement for all students. A National Junior Honor Society chartered in the fall of 2004 recognizes students who have excelled academically.

For State Accountability purposes, the State Board has placed all schools into the “No Grade” category for the 2022-2023 school year. Therefore, a state report card for 2022-2023 is not available.


Parent Involvement

Grissom has a Parent Teacher Organization (PTO) which provides strong support to the school and students.  Many volunteer hours are logged by members to assist in activities and special projects.  The funds raised by the PTA are distributed to benefit all students at Grissom.
