An OAP clinical supervisor is a Board Certified Behaviour Analyst (BCBA) or equivalent qualified professional who designs and oversees your child's ABA therapy plan. Under OAP Core Clinical requirements, the clinical supervisor must provide at least 1 hour of supervision per 10 hours of direct therapy delivered by technicians. This ratio is required for OAP billing compliance.
Start with the short answer, then reveal deeper context where helpful.
The clinical supervisor is the qualified professional responsible for designing your child's individualized behaviour intervention plan (IBIP), conducting functional behaviour assessments, monitoring treatment progress, and adjusting programming based on data. Under OAP Core Clinical requirements, the clinical supervisor must be a Board Certified Behaviour Analyst (BCBA), a Board Certified Assistant Behaviour Analyst (BCaBA) under BCBA supervision, or a psychologist with equivalent ABA competencies.
OAP Core Clinical billing requires that a minimum of 1 hour of BCBA supervision be provided for every 10 hours of direct therapy (RBT-delivered). This 10:1 ratio is a minimum — clinically, higher supervision ratios are often recommended for younger children or those with more complex presentations.

The clinical supervisor does not typically deliver all direct therapy — this is done by Registered Behaviour Technicians (RBTs) or equivalent paraprofessionals under the supervisor's direction. The supervisor is responsible for training, overseeing, and evaluating the RBTs working with your child.

Supervision can be delivered in-person or via telehealth. It includes: direct observation of therapy sessions, data review meetings with the RBT, parent training sessions, and the creation or revision of the behaviour plan. Families should confirm with their provider what supervision activities are included in the billed hours and how often they will meet with the supervising BCBA.

WHO recommends accessible, community-based early interventions for children with autism — timely evidence-based psychosocial interventions improve communication and social engagement
Early Start Denver Model (ESDM) delivered to children aged 18–30 months produced significant gains in IQ, adaptive behaviour, and autism severity — some children no longer met diagnostic criteria at follow-up
Cochrane systematic review finds evidence that early intensive behavioural intervention (EIBI) may produce positive effects on adaptive behaviour and communication for young children with ASD (low certainty of evidence)
Evidence supports autism screening and intervention commencing in the first 2 years of life — earlier identification directly enables earlier intervention during the highest neural plasticity window
