How to choose an ABA therapy provider

  1. Check the license with the state or provincial board that issued it; most boards publish a free online lookup.
  2. Make sure ABA therapy is a regular part of their work, and ask what approach they use and why.
  3. Ask how many hours a week they recommend and how they set goals with the family.
  4. Ask how often a BCBA observes sessions and meets with parents.
  5. Ask about fees, insurance and the cancellation policy before the first session. In the US, if you are uninsured or paying yourself, you can ask for a good faith estimate of expected charges.
  6. Check practical fit: in-person or online sessions, evening times, and how soon they have an opening.
  7. After a few sessions, ask yourself whether you feel heard. Changing to a different provider is common and fine.

Questions to ask an ABA therapy provider

  • Are you accepting new clients, and how soon could I start?
  • Which license do you hold, and in which state or province?
  • How much of your work is ABA therapy?
  • Is there a waitlist, and do you accept my insurance?
  • What do you charge per session, and do you take my insurance or provide a superbill?
  • Do you offer online sessions?
  • What is your cancellation policy?
  • What do you keep confidential, and when would you have to share information?

Who provides ABA therapy?

ABA programs are designed and supervised by board certified behavior analysts (BCBA). Day-to-day sessions are often delivered by registered behavior technicians (RBT) working under that supervision.
