My 7yo is on an IEP. His private BCBA requested to do a school observation, to help us figure out how to best support him at home, as well as additional accommodations to request at school. The school has stated she is only allowed to do a 20 min observation, and only with me and the principal present as well. I work full time and cannot be there, plus if I'm there it has a significant chance of changing his behaviors in the classroom. We are in CA. Is there any regulations around classroom observations?
