Pivotal Response Treatment (PRT), developed by Robert and Lynn Koegel at UC Santa Barbara, is a naturalistic ABA-based intervention targeting four pivotal areas: motivation, responsiveness to multiple cues, self-management, and social initiations. The National Autism Center's National Standards Project (2015) classifies PRT as an established evidence-based practice. PRT is eligible for OAP core clinical funding in Ontario as a recognized behavioural intervention delivered by qualified ABA providers.
Start with the short answer, then reveal deeper context where helpful.
Unlike discrete trial training (DTT), which uses structured, therapist-led teaching at a table, PRT embeds learning opportunities in naturalistic, child-initiated activities. The child chooses activities, and the therapist creates learning opportunities within those preferred contexts. This approach increases motivation and promotes generalization of skills to everyday settings.
PRT is delivered by ABA professionals (BCBAs and RBTs) with specialized PRT training. In Ontario, many ABA providers incorporate PRT strategies within their programs, particularly for children who respond well to naturalistic, play-based learning. PRT can be delivered in home, clinic, or community settings.

PRT targets four "pivotal" areas that, when improved, produce widespread positive changes across multiple developmental domains. These are: motivation (using child choice and natural reinforcers), responsiveness to multiple cues (attending to relevant features), self-management (self-monitoring behaviour), and social initiations (seeking out social interactions). Research by Koegel et al. (1999) demonstrated collateral improvements in untargeted behaviours when pivotal areas are addressed.

Because PRT is classified as an ABA-based intervention, it is fully eligible for OAP core clinical funding. Families should ask potential providers about their experience with PRT specifically, as not all ABA providers have formal PRT training. The PRT training credential is offered through the Koegel Autism Center.

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)
