I cringe when I hear "private gifted school in CA" because of the extremely expensive, truly horrible two years we did that. We are now in a public charter with no GT program per se, but my DS is happy to go to school, learning new things every day and has his emotional needs met too. It often just depends on the teachers and the school's flexibility, far more than a term or program name.

PM me if you want specific info about our former school.
