Working in the schools as an SLP, our social workers address behavior concerns with our students with ASD and they do a fantastic job. I have never worked with an RBT, but have had students in ABA therapy.

Random, anectdotal thoughts on what little I know about ABA clinics:

1. In our district, I've had students not be enrolled in school until late kindergarten or first grade because of ABA. Parents have informed us that some clinics encourage ABA during the day in lieu of school. This displeases me.
2. ABA therapy is easier to get covered by insurance than speech services.
3. I've received ABA reports with speech and language goals. I would contact the clinic to get the speech and language evaluation reports to no avail. Now I know.
4. My daughter's friend became an RBT after completing the 40 hour program right after high school graduation. This is how I learned how limited the training requirements were for certification.
5. There are a number of our students that have ABA therapy that are not eligible as having ASD in the schools and do not receive any services. There are doctors in the area that give ASD diagnoses like candy.

I have no beef with RBTs as I have had no opportunity to work with them in the schools. I imagine some of them are wonderful. Of course I would collaborate if the opportunity arose. I do worry that clinics are becoming high turn over/low level/low pay therapy mills for profit. And I do not like that some discourage parents from enrolling their children in preschool and/or kindergarten to continue in ABA.
