This newly established High School would only be fully operational by school year 2007–08. However, the scheduled return of the Mapua Junior varsity team in NCAA Season 83 (2007–08), did not materialize and instead it resumed participation in NCAA Season 84 (2008–09). After it was revealed that several players of the PCU juniors' basketball team enrolled with spurious documents, PCU's seniors and juniors teams were suspended in the 2007–08 season. The seniors teams participated in the 2008–09 season, but all teams would take an indefinite leave of absence starting with the 2009–10 season. As a result, the Management Committee conducted a search for PCU's replacement but it was decided that such replacements would be deferred to the 2010–11 season. The league opted to invite guest teams instead, with Angeles University Foundation, Arellano University (AU) and Emilio Aguinaldo College (EAC) being the invitees, and being eligible to win championships.

Arellano became a regular member since the 2013–14 season after meeting the league requirements. EAC and Lyceum were accepted by the league as regular members starting 2015–16 season. Due to the loss of the congressional franchise of ABS-CBN, GMA Network and GMA News TV (later GTV since February 22, 2021) will air the future seasons of the NCAA for 5 years, from Seasons 96 to 101.

These rivalries have declined in recent years with the withdrawal of two of the old-timer six, Ateneo and La Salle. With the addition of new members to the league, rivalries shifted to more of a geographical nature. However, the former members would still face their old rivals in other leagues during the off-season, such as the Home and Away Invitational League, the Philippine Collegiate Championship, and the Shakey's V-League. Ateneo–UP A rivalry between the Ateneo de Manila and the University of the Philippines existed even before the formation of the NCAA. UP students would troop from Padre Faura to
