Hi Swati. I don't live in the Valley anymore but I do know Cupertino district is the best overall. That's why it's so expensive there! In our personal experience the private schools were totally unprepared for my daughter's special needs so I would not recommend that unless perhaps a new specialized school has opened (of which I'm not aware). See if Cupertino has a CAC (parent advisory group to the district) and connect there. That would be you best resource for everything local. You'll probably need support in getting an IEP going so maybe google advocates in the area? Good luck!
