 Initially only grades 1-6 were offered, but in 1961 construction began on a junior/senior high school to offer secondary education (grades 7-12) on post.The 6th grade was later moved to the junior/senior high school and the PK and kindergarten grades later added.Currently, only students whose parents physically reside on either Fort Sam Houston or Camp Bullis have automatic right to attend Fort Sam Houston ISD schools; students whose parents are assigned to either installation, but reside off-post, can be accepted as transfer students, but the parents must provide transportation.
