 BCS provides full-time teaching specialists in the arts and sciences, a Mandarin language program, and optional after-school activities.The school is funded in approximately equal parts from state funding and parent donations.BCS was founded by local residents as a reaction to the decision of 10 February 2003 by the Los Altos School District (LASD) Board to close Bullis Elementary School in Los Altos Hills (this school later re-opened as Gardner Bullis School in 2008).
