PREP’s goals are to improve students’ attendance, persistence, and academic proficiency, consequently raising graduation rates and promoting successful transition to postsecondary careersand education. Throughout the course of the grant, PPS implemented PREP in six schools.  \nThe PREP intervention promotes student engagement by integrating three key components: project-based learning (PBL); career technical education (CTE), including certified CTE programs and career-related learning experiences (CRLEs); and social and emotional learning (SEL) . The evaluation also measures a fourth component, engaged leadership, as a key condition for successful implementation. While the schools studied here may have implemented one or more of these components prior to PREP, the intervention theorizes that implementation of all four components will lead to improved student outcomes.  \nEducation Northwest conducted an external evaluation of PREP to measure the fidelity of implementation and to assess the impact of the intervention. The evaluation team developed indicators and thresholds to measure implementation fidelity and applied this framework to data collected during two years of implementation (2020-21 and 2021-22) . The evaluation team conducted two studies to examine the impact of PREP using a comparative interrupted time series. The first study (Study 1) compared attendance, retention, and credit accumulation outcomes between four schools participating in PREP and four other alternative schools within the same district during the 2020-21 school year. The second study (Study 2) compared attendance outcomes between six schools participating in PREP and sixteen other alternative schools across Oregon during the 2020-21 and 2021-22 school years. This report describes the findings of the implementation and impact studies, with a deeper focus on the impact study.  \nResults from the evaluation uncovered the following findings:  \n● PREP key components were implemented with adequate fidelity during the 2020-21 school year. Results from the implementation analysis found that three of the four PREP key components and one of two mediators were implemented with adequate fidelity during the 2020–21 school year.
