Membership was fluid, and the composition of the association changed frequently. To this date, San Beda is the only founding member left in the association. The old-timer six (1936–68) After National University, University of the Philippines Manila, and University of Santo Tomas left the NCAA in 1932, the Ateneo de Manila, Colegio de San Juan de Letran, De La Salle College, José Rizal College, Mapúa Institute of Technology and San Beda College continued the association and its membership remained unchanged for several decades. World War II interrupted the NCAA's activities in 1941, but the association resumed operations after the war in 1947. First expansion (1969–78) San Sebastian College–Recoletos was admitted in 1969, marking the first change in the NCAA's membership since 1936. This increased the association's membership to seven colleges. Trinity College of Quezon City was also admitted in 1974, the association's golden anniversary, according to publications of the day.

The association ordered the game to be replayed behind closed doors but the then-FIBA recognized basketball association, the Basketball Association of the Philippines, ordered the association to cancel the rest of the season.
