Pivotal Response Training, like ABA, is based on discrete trials.

Unlike most traditional ABA programs, these trials take place in a more natural play setting. In this way it has similarities to Dr. Greenspan's floor-time program--one might say that it elements of both of these proven approaches.

PRT was developed by Robert L. Koegel and Laura Schreibman.  As of this writing, the efficacy of PRT is still under investigation.  Clinicians at the University of California at San Diego's Autism Research Laboratory have received NIMH funding to work with children and their parents using either PRT or an ABA-style discrete trials method. Some information is available now, including a parent training manual and a Web site.
