Pivotal Response Treatment (PRT) and other therapies for autism have been developing and changing in recent years, and have moved away from clinical settings to options that can be used in the classroom and at home. Common current therapies focus on improving social skills and increasing communication. The therapies and treatments that are available for children with autism spectrum disorders are as varied as the children whom they support. As PRT and other therapy plans evolve, parents and clinicians develop higher expectations that children with autism will develop lost skills.
