Despite institutional efforts, growth in the number of faculty of color has largely plateaued, limiting research innovation and other benefits of diversity. In this article, we seek to understand structural barriers to faculty equity by (a) detailing a theory of epistemic exclusion within academia and (b) applying the theory of epistemic exclusion to the specific context of faculty departmental reviews of scholarly research (e.g., annual review, promotion and tenure review). Epistemic exclusion is a form of scholarly devaluation that is rooted in disciplinary biases about the qualities of rigorous research and identity-based biases about the competence of marginalized group members. These biases work in tandem to systemically and disproportionately exclude marginalized scholars (e.g., people of color, women) from the academy. In the context of faculty departmental reviews, epistemic exclusion can happen in formal systems of evaluation through criteria, metric, and application exclusion. It can also occur informally during interpersonal interactions and communications through legitimacy, contribution, and comprehension exclusion. In this article, we detail each of these types of exclusion, how they may interact with each other, and their consequences. We assert that epistemic exclusion threatens the diversification of academia and offer suggestions for equitable evaluation practices and reducing epistemic exclusion within higher education broadly.
