You would do well to avoid the Art Insitute! They have been sued many times!
OCC does have a Baking and Pastry Arts program, but so do LBCC, and LATTC.
After perusing their online program descriptions, OCC's Baking and Pastry Program does not appear to be as comprehensive as LATTC's program, which is a 2-year program, and is ACFEI-accredited. LBCC offers courses in Chocolate and Cake Decorating, is a 2-year program.
If it were me, I would probably not attend OCC, but would probably choose LATTC. It seems to be the most comprehensive program of the 3 colleges, and seems to be best community college baking program in southern California.
Private Culinary, Baking and Pastry Arts schools are simply not worth the exhorbitant tuitions that they charge, especially when one considers that the end result is to get a minimum-wage, or near minimum-wage, entry-level, food-service job!

Good luck in your studies!
