Why is ABA controversial?
Some autistic adults report that ABA caused them harm. Behavior analysts say today's ABA differs from what those adults experienced. You'll find both sides below with their sources, followed by questions for judging any provider.

Questions for any ABA provider
- Can I watch sessions at any time, either in person or by video?
- Which person sets the goals, and how do you include what my child wants?
- When my child says no or feels upset, what do you do?
- Do you ever punish a child or hold them down? When?
- For stimming that doesn't hurt anyone, such as rocking or hand-flapping, what's your approach?
- How often will I meet with the behavior analyst, and what method is used to measure progress?
Calm, clear answers are a good sign. A provider who won't let you watch is a reason to keep looking. So is one who wants to stop harmless stimming only because it looks different.
