This instrumental case study documents a community-based participatory evaluation research (CBPER) project that involved a community partner, two graduate students, a faculty member, and an external funder. It highlights the fact that a participatory evaluation model is a viable way to conduct community-based research (CBR) when a community organization needs to know if the program services they are offering are effective. The identification of the promising aspects and shortcomings of this project advance the theoretical and methodological understandings of the CBR field and promotes better CBR practice.
