School for neurodivergent 1st grader?

Our kiddo is in 1st grade at a public dual immersion school in Oakland. He's falling behind academically and behavior is a huge issue. He has an IEP, we're currently in process of getting IEEs.  He has ASD and likely ADHD. Although we love many things about the school community and he has good friends, I fear the school is not a good fit for him. Exploring options, including charter, private or out of district. Any suggestions for schools that worked for your kids? Also would love to hear from you if you have gone through this and recommend staying at the same school while trialing ADHD medication and getting the IEE, maybe those things will be game changers? Any advice welcome.
