Evidence-based therapy that uses principles of learning to improve socially significant behaviours. ABA is the most widely researched intervention for autism and focuses on teaching new skills while reducing challenging behaviors. While Applied Behaviour Analysis (ABA) is considered highly effective, especially during the critical window of ages 2-6 for maximum developmental impact; beneficial at any age, families depending on the Ontario Autism Program face a severe bottleneck. Currently, 77% of registered children are waiting to access core services like ABA.
Without timely public funding, families must either pay out-of-pocket or rely on private insurance. The average intensive ABA program costs between $30,000 and $80,000 per year.
These are general process questions worth asking any aba provider — not claims about a specific provider's answers.
