Youth-led STEM programming depends on skilled adult facilitators who can support authentic teen leadership, yet professional learning for developing these specialized skills remains understudied. Through three cycles of design-based research, we iteratively developed and studied a professional development model that trained informal educators from museums, libraries, afterschool programs, and schools to launch Teen Science Café programs—a youth-led model where teens organize STEM events. Analysis of data from trainer reflections, trainee interviews, trainee surveys, and implementation tracking across three iterative design cycles revealed six interconnected principles essential for effective professional development: focusing on a committed adult leader; personalized training characterized by mutual respect; learning by doing; establishing accountability that builds momentum; enabling learning from peers and near-peers; and recognizing success to nurture professional pride. Implementing these principles to prepare educators to center youth voice requires substantial, coordinated investment across stakeholders—commensurate with the complexity of developing youth agency and STEM identity in informal settings. From our findings, we contrast this approach with the “efficiency trap,” in which scaled training without sustained support wastes resources when many educators are trained but youth-centered programs fail to materialize.
