The purpose of this article is to provide an overview of logic models and their role in the creation of PD programs and in the evaluation of outcomes. The authors provide an example of how a logic model can be used with PD programs by providing a description of its use with the Indiana Resource Center for Autism's (IRCA) School Team Training program. The authors focus on how the use of a logic model allowed the IRCA to restructure the team training program to more systematically evaluate and document the outcomes of the school team training program.
