I have two kids who have gone to Classen SAS, one loves it and it was not a good fit for the other. It depends on the kid. If your child has not been exposed to high school kids, it is a big shock to be in a 6-12 grade environment. There is a lot more swearing, references to poor behavior, etc. However, Classen is for motivated kids. I believe that is one of the reasons for the teachers laid back attitude a reviewer mentioned. One of the great things about the school is that almost all of the other kids are as motivated to succeed as your child. I would certainly rather my kid stumble with homework and grades in middle school than in college. Plus, there is no other school in Oklahoma City that offers an IB program, which is recognized internationally. We have found inspirational teachers at Classen, (and one man who was in the science department, is misogynistic, and should have left a long time ago). For all the rest, these are professionals who purchase their own supplies, talk to kids as if their opinion matters, and work before or after school with the kids. I believe teachers have to be on a mission. Between the hours they work and the money they are paid, it is charity work. Classen does a whole lot with a very small budget - all the extra money they could get for awards and excellence is spread among all the OKC public schools. Is that right? Is that fair? I don't know. Seems like they should at least get a larger share. But, that is a fight for another day. For now, here's to the excellent educators who are helping our children succeed!
