The goal of diversion is to divert a youth from the formal process of the juvenile justice system - which may provide a stigmatizing, adverse effect on his/her behavior - into a program that holds the youth accountable for his/her behavior through mandatory participation in programs that address the needs underlying his/her problem behavior. This I-Guide is designed for juvenile justice systems that are interested in implementing a pre-adjudication (prior to a court appearance) diversion program. The program would be offered at arrest, intake, or referral. This I-Guide focuses on the beginning stages of implementing a post-arrest, pre-adjudication diversion program. It does not address diversion programs initiated by law enforcement agencies or schools. The I-Guide includes research and evaluations of evidence-based diversion programs that meet certain standards. One standard is that the program divert youth from formal processing by the juvenile court system prior to any adjudication proceeding. A second standard is that evaluation of the program examined any outcome related to the behavior or well-being of diverted youths and their families. The I-Guide addresses steps in starting, supporting, and sustaining the evidence-based diversion program. Access to each of the I-Guide steps is provided on this web page.
