Purpose: Considering the lack of practical Comprehensive School Physical Activity Program (CSPAP) experiences within Physical Education (PE) Teacher Education, the study's purpose was to examine the experiences of PE preservice teachers, a PE teacher, and the university faculty who implemented a CSPAP, and the students who participated in the program. Method: An 8-week before-school program was implemented in a middle school from Fall 2018 to Spring 2022. One hundred three preservice teachers assisted in implementing the program as part of coursework. Data were gathered through preservice teachers' journals and focus group discussions, interviews with the university faculty and PE teacher, and students' surveys. Results: Data were inductively analyzed, and themes were expand preservice teachers' view beyond PE, benefits for preservice teachers and students, and future opportunities. Discussion/Conclusion: Incorporating CSPAPs into PE Teacher Education curriculum through school-university partnerships can provide practical experiences for preservice teachers to build competency in implementing CSPAPs in schools.
