Intensive ABA
Intensive ABA (20-40 hrs/week)
- Strengths
- Strongest evidence base for significant gains
- Rapid skill acquisition during critical period
- Comprehensive programming across all domains
- Research supports intensive early intervention outcomes
- Limitations
- Extremely expensive without full OAP core funding
- Demands significant family schedule changes
- May be too demanding for some children
- Limited time for other activities and therapies
Focused ABA
Focused ABA (10-15 hrs/week)
- Strengths
- More affordable and manageable for families
- Time for school, other therapies, and family life
- Targets specific skill areas effectively
- More feasible with OAP interim funding amounts
- Limitations
- Slower rate of progress than intensive model
- May not be sufficient for children with complex needs
- Less comprehensive skill coverage
- May not close developmental gaps as quickly
Analysis
ABA intensity should follow an individualized assessment. The plan should consider goals, tolerance, assent, family capacity, cost, and what to do if the child is distressed.
Frequently asked questions
Legacy interim funding was one-time and limited to registrations before April 1, 2021. It did not reliably cover intensive programming. Current families should confirm available OAP streams with AccessOAP.
Ask the clinician to justify the proposed hours with evidence, goals, and a safety plan. The cited Cochrane EIBI fact describes possible benefits with low-certainty evidence.
No. Older children can still learn useful skills. Ask the clinician what goals are realistic, what evidence supports the plan, and how progress will be measured.
