Chatsworth Hills Academy was founded in 1977 by a group of public school parents led by Liz Stillwell Shapiro.

Following a co-op model, parents volunteered their time in their areas of expertise to clear the land, pour concrete, install buildings, run wiring, develop curriculum, buy books, and hire instructors.

Chatsworth Hills Academy participates in a full range of interscholastic athletics as a member of the San Fernando Valley Private School League (SFVPSL).

Beginning in fourth grade, boys' teams include Flag Football, Basketball, Soccer and/or Volleyball during the school year.

Over the past several years, many CHA school teams have made play-off berths and have won league championships.

Chatsworth is an inland part of the coastal region of southern California that was the historic homeland of the Chumash Indians.
