This training provides an overview of diversion and community supervision and the role that behavioral health providers can play in supporting clients who are mandated to treatment by the court, or as a condition of probation or parole. First, we will outline the processes involved in diversion and the requirements/mandates that are often imposed upon clients who participate in “alternative to incarceration” programs. In addition, we will examine the systems of probation and parole, and the requirements that these systems impose on clients. Whether mandated by the court through diversion or as a condition of probation or parole, behavioral health providers must learn to collaborate with these systems and play a role in monitoring and reporting clients’ progress. Through interactive and didactic training approaches, trainees will learn strategies and best practices for working with mandated clients and collaborating with the systems that oversee their treatment progress. Please only register for this training if you are a FACT provider or an ACT provider serving justice-involved clients in California.
