NASP's Annual Regional Leadership Meeting (RLM) brings together leaders for training and discussions about issues important to school psychology. For 2023, RLM for the first time included affinity groups as part of the implementation of NASP's equity, diversity, and inclusion (EDI) plan. This article will define affinity groups and describe the process by which the authors developed, facilitated, and evaluated the RLM affinity groups. The intent is to provide guidance to those interested in creating affinity spaces in their state associations, districts, graduate programs, and other professional spaces.
