At the High School level for Girls House, CYA participates in a Friendship League, which includes teams from VYI (Vienna), SYA (Centreville), FPYC (Fairfax), Burke, Turnpike, and Braddock Road. CYA high school girls teams play both other CYA teams and teams from these other local programs. There are two divisions of play: Girls 9-10th grade and Girls 11-12th grade (some grade exceptions are allowed).
Most of the games take place at local CYA-area gyms (Chantilly HS, Oakton HS, or Carson MS) but some games may be scheduled in gyms located in Vienna, Centreville, Fairfax, Annandale or Burke.
Registration for HS girls does not close until November 30th in order to accommodate the tryouts held by the local High School teams (Chantilly, Oakton, and Westfields). Skills assessments for the CYA girls high school teams will probably takes place at the beginning of December.
