involving the second, third, fourth, fifth, sixth, seventh, eighth and ninth placed clubs. Below is a complete record of how many teams played in each season throughout the league's history: Controversies about promotion to Liga ACB Until 2012, in the 29 editions played of the Liga ACB, only three teams declined promotion, due to acting as reserve teams or for lack of funds: CB Guadalajara and CB Cornellà in 1993 and CB Cajabilbao in 1994. Since 2012, due to the financial crisis that started in 2008, only two teams (Canarias and Andorra) of a possible 10 could promote to Liga ACB. This started a discussion about the promotion requirements of the ACB, considered by the LEB Oro clubs as "disproportionate". For clubs that promote and would make their debut in the ACB demands: An arena with a minimum capacity of 5,000 seats. An inbound of €3m. For clubs that return to the league after a promotion, an update of the inbound is demanded. A deposit of €1.7m that would be returned in case of relegation to LEB Oro.

In 2013, neither CB Atapuerca, Ford Burgos by sponsorship reasons, nor Lucentum Alicante could promote. The latter resigned also to play in the second league and joined the fifth division. In 2014 and 2015, CB Tizona, also Ford Burgos by sponsorship reasons, did not promote despite achieving the place two years in a row. After its second failed promotion, the third in the city of Burgos, the club sued the Association any accused them of "distorting the reality". Also in 2015, despite having played in the league during the 1980s and 1990s, Club Ourense Baloncesto was not admitted in the league despite fulfilling all the requirements, after not passing an accounts audit. However, ACB would admit Ourense for the 2016–17 season if it fulfilled the requirements regardless of their position in the 2015–16 LEB Oro season.
