If services for your child is of the utmost importance it might be best to rent until you find a school situation that you like for your child. It’s a lot easier to pick up and move if things aren’t working in the school district. I assume your already involved with the regional center. If you are talk to your case worker and see if they have any recommendations. They know which school districts are better to work with than others. with the budget difficulties in CA it’s pretty likely special needs services are going to face cuts and those cuts will be handled differently by each school district.
