The positive behavioral interventions and supports (PBIS) framework has been applied for over two decades in public schools throughout the country. More recently it has been adopted, or is being considered for adoption, by an increasing number of states and facilities providing residential or secure care for juvenile offenders. During implementation these jurisdictions, like public schools, experience challenges during initial implementation and in achieving sustained implementation. In this paper, we discuss issues related to sustainability of PBIS in secure care settings. We describe recommended practices and unique characteristics of secure care that may affect sustained implementation.
