ABSTRACT Applying the analytic lens of critical whiteness, we examine the relationship between facilitation structures and the quality of racial dialogue in educator professional development. We draw on data from a five-session virtual ‘antiracist reading group’ in a rapidly diversifying U.S. district, convened and facilitated by a White district leader. Observed discussions tended towards the superficial and did little to challenge participants’ existing worldviews. We argue that the leader’s facilitation decisions characterised a ‘hidden curriculum’ of safety and comfort that inhibited participants’ development. These moves were further shaped by and reified persistent manifestations of whiteness. We offer implications for the facilitation of antiracist professional learning, equity leadership, broader policies related to equity, and future research.
