How to choose an ABA therapy provider
- Check the license with the state or provincial board that issued it; most boards publish a free online lookup.
- Make sure ABA therapy is a regular part of their work, and ask what approach they use and why.
- Ask how many hours a week they recommend and how they set goals with the family.
- Ask how often a BCBA observes sessions and meets with parents.
- 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.
- Check practical fit: in-person or online sessions, evening times, and how soon they have an opening.
- 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?
