This Formative Evaluation Lessons Learned template captures the major findings and lessons learned from the formative evaluation of the Youth Transitions Partnership (YTP) program in Alameda County, California. The YTP program is an intervention built around the core components of intensive case management and Dialectical Behavior Therapy (DBT). In partnership with Alameda County's Department of Children and Family Services (DCFS), First Place for Youth (FPFY) served as the program provider, bringing overall case and systems coordination to the YTP program, and Chapin Hall at the University of Chicago served as the local evaluator, conducting a comprehensive formative evaluation which included implementing a CQI framework. The formative evaluation addressed questions about the extent to which process, quality, and capacity investments were deployed to support the installation and initial implementation of the YTP model as well as questions about program engagement and the short- and medium-term outcomes of program participants. These questions include: (1) Does the administrative risk assessment process correctly identify members of the target population?; (2) Are enrollment staff able to connect with and enroll youth?; (3) Is the intensive case management component of the intervention being delivered as intended?; (4) Is DBT being delivered to program participants as intended?; and (5) Is there evidence that program participants are progressing toward short- and medium-term outcomes?
