This article explores the dynamic practice of inviting community members to grade college students on their work in community-engaged partnerships. The authors articulate theories of writing assessment with theories of reciprocity to argue that community-based student evaluations can be a valid and ethical form of assessment, and discuss a case study in which local youth graded college students to offer eight best practices for implementing community-based assessment. As reciprocity is often underemphasized in practice, community evaluations provide a strategy for shifting power toward community members, potentially reinvigorating applications of reciprocity to make them more substantial and meaningful.
