Social and emotional learning (SEL) is a key focus of early childhood education. A significant body of research demonstrates the critical impact of fidelity of SEL curriculum and intervention implementation on child outcomes; however, few widely-used curricula regularly assess classroom-level implementation fidelity outside of the context of research or correlate fidelity with key areas of children’s development of these skills. Fidelity measurement often focuses on easy-to-quantify variables such as classroom environment or lesson plan adherence, and is a periodic snapshot used as a moderator or co-variate when assessing child outcomes, rather than being intentionally leveraged as a systematic, ongoing process to evaluate and support implementation. In this paper, we present a novel approach to capturing fidelity data as a core component of professional development. We outline our findings from a pilot of our approach using short, teacher-recorded videos submitted across the school year as a vehicle for capturing and sharing real-time data related to professional learning, implementation, and curricula impact, as well as a framework for building equitable partnerships with teachers.
