In the past several years, the values and practices of positive behavior support (PBS) have had a significant impact on services provided to adults and children with disabilities. Evidence of this impact can be seen in federal grants and laws such as the Individuals with Disabilities Education Act Amendments of 1997 (IDEA, 1997), a professional journal (the "Journal of Positive Behavior Interventions"), and an established organization (the Association for Positive Behavior Support). With this emergence comes a continued need for clearly defining PBS, identifying the skills evident in a competent practitioner, and effectively teaching those skills to supervisors, teachers, direct support staff, and other professionals. It is with these concerns in mind that we will review the training materials "Positive Behavior Support Training Curriculum: Supervisory and Direct Support Editions" (PBS-TC).
