If you''re considering ABA, the single most important decision is not "ABA or not" — it''s which provider. Practice quality varies enormously.
Green flags
- Assent-based practice. The child''s "no" (verbal, gestural, or behavioral) is respected. Sessions pause when the child is distressed.
- Play-based and naturalistic. Learning happens in the child''s natural environment (floor, playground, kitchen), not primarily at a table.
- Neurodiversity-affirming language. The provider talks about supporting the child, not "recovering" them or making them "indistinguishable from peers."
- Reasonable intensity. For toddlers, 10–20 hours/week is typical for focused programs. 40 hours/week for a 2-year-old is a red flag.
- Parent collaboration. You set goals together. You can observe sessions any time.
- Stimming is not a target unless it''s causing injury.
- BCBA involvement. A BCBA (not just an RBT) is present regularly, not once a month.
- Trauma-informed training and staff who have read autistic-authored critique.
Red flags
- Refusing to let you observe sessions.
- Using food, toys, or affection as contingent rewards a child must "earn."
- Physical prompting a child who is trying to leave.
- "Quiet hands," forced eye contact, or extinction of stimming as goals.
- Marketing language: "recovery," "indistinguishable," "cure," "beat autism."
- Pressure to sign up for 30–40 hours immediately.
- No clear plan to fade services over time.
- Dismissive of autistic adult perspectives.
Interview questions
- "Walk me through what you''d do if my child cried and pushed materials away."
- "What''s an example of a goal you would refuse to work on?"
- "How do you measure success — and does the child''s happiness count?"
- "How do you handle disagreements with parents about goals?"
Watching a session
Before committing, watch a full session (in person or via video). Look for: is the child smiling? Engaged? Free to move? Do they seek out the therapist, or avoid them? Trust your gut — you know your child.
If ABA isn''t the right fit
Alternatives with growing evidence include: speech-language therapy, occupational therapy (especially sensory integration), Floortime/DIR, NDBIs like ESDM and JASPER, and family-focused parent coaching. Many families combine services.
