This dissertation study focused on an interagency collaboration in juvenile justice which aimed to improve education and employment outcomes for youth and young adults. The period of reentry (also known as reintegration or transition) typically includes supports in education, employment, work experience, and mental health which have been shown to improve youth outcomes (Mizel & Abrams, 2020). Utilizing qualitative design, this study aimed to determine what practices contributed to proficient collaboration and information transfer during an interagency collaborative project. Data was collected from participant interviews and meeting documents such as agendas, notes, and process charts developed during the collaborative project. Results included nine areas of note (Staff & Resources, Communication, Data Processes, Personnel Trainings, Edits to Flowchart, Logistics of Systems & Services, Special Education, Major Barriers, and Future Collaboration Efforts). Implications and Recommendations are discussed. [The dissertation citations contained here are published with the permission of ProQuest LLC. Further reproduction is prohibited without permission.
