Fort McCoy High School was closed in 1963 and re-opened soon after as Fort McCoy Elementary School. The population of Fort McCoy increased over the years, and by the 1980s the property was a vast land full of "portable classrooms". Due to the population increase and age of the building (50 years old), the Marion County School Board decided to have a new school built in 1986. The original brick building became the Fort McCoy Public Library in 1996, after a $60,000 renovation. In 1988, the new campus opened, renamed as Fort McCoy School, which now served elementary and middle school students (Pre-K to Eighth grade). That campus is still being used today, as well as the same grade levels being served.
