There has been increased focus within the evaluation field on the value of community-engaged research (CER) methods; however, CER is not easily seen as compatible with experimental evaluation methods (or randomized controlled trial, RCT). For instance, in an experimental design, researchers leverage randomization to create a counterfactual; this can inhibit flexibility in implementation often connected to CER practice. This article describes the central tenets of both CER and randomized evaluations, highlighting tensions between principles of each. It describes a community-partnered RCT designed to evaluate the impact of an afterschool youth music program. We outline our process of designing and implementing the study in partnership with a community-based organization, including successes and challenges. We identify key lessons and make recommendations for evaluators who seek to engage in similar work.
