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.
