Former football-only members After expansion in the
Colonial Athletic Association brought that conference to 6 football-playing schools, it was agreed that the CAA would take over management of the Atlantic 10's football conference starting in the 2007–08 school year as the legally separate entity of
CAA Football. All the schools on this list (except Boston U. and Connecticut) were in the A-10 football conference when it became CAA Football, but Hofstra and Northeastern discontinued their football programs after the 2009–10 school year. Membership dates include time in the
Yankee Conference (which was an all-sports conference from the 1947–48 to 1975–76 seasons, and a football-only conference after that) which merged into the A-10 in the 1997–98 school year. ;Notes:
