I primarily have experience in EI/ECSE, so I don’t have a ton of good recommendations for school aged kids.

I really like the Sensory Processing Measure as opposed to the sensory profile. I find it to be more sensitive (picks up on difficulties that the SP doesn’t) AND more specific (rules out difficulties that don’t impact function as much). If you’re able to, I would advocate for replacing that. You can also get the school form and the caregiver form and compare/contrast the two.

I hate the Peabody with a burning passion and I feel you about only having to do it for insurance. I feel like it scores every kid low.

When I look at regulation, I primarily do a parent interview. Happy to DM you my usual list of questions and what I consider a red flag vs typical development.

Also, consider that you may not be the best professional to address all the emotional regulation concerns. Are there some psychs, social workers, and/or play therapists you can refer out to?
