CIF Southern Section Girls Basketball Playoff Computer Rankings - Jan. 21, 2026

With just a few weeks left in the regular season, the playoff divisions are starting to take shape. The CIF Southern Section will continue to keep calling its top playoff bracket the 'Open Division' while the subsequent divisions will now be Divisions 1 through 9.
In the past, each division had a single-A and double-A designation from Division 2 through 5 (2AA, 2A, 3AA, 3A ...). That will no longer be the format moving forward, according to the CIF's basketball bulletin.

As teams are vying for league placement, which will determine their playoff eligibility, working in the background is CIF's 'competitive equity' model that uses computer rankings to determine where teams should fall come playoff time. The computer will determine which division and where within that division a team should be placed based on the results on the current year.
That said, High School On SI provides the computer rankings that the CIF Southern Section will use to create its playoff divisions in February. The first edition of those rankings was released on December 29.
