With what ages is PRT effective?
According to the studies that form the evidence base for PRT, children from 2 to 16 years of age
have benefitted from PRT intervention. Research has shown that the use of motivational
techniques inside PRT’s teaching framework can lead to 85-90% of children with autism, who
begin intervention before the age of 5, developing verbal communication as a primary mode of
communication. More recently, though, researchers have identified specific behavioral
characteristics associated with favorable responses to the teaching practices. Precursors
related to positive outcomes thus far, include increased use of social initiations, less social
avoidance, more toy play, and stereotypic language.
