School climate surveys are frequently used to collect information about student experiences in school. Less is known about how educators use survey data after survey administration. This paper explores one school district's critical use of evidence to promote equitable change. We conducted eight semi-structured interviews with district and school leaders to investigate their uses of evidence. Through our qualitative, reflexive thematic analysis, we generated six themes: (1) using evidence to provide a common language; (2) bringing attention to trends to shift staff understanding of problems, (3) making structural changes, (4) planning for professional learning, (5) following up directly with students, and (6) engaging with the community. Findings illustrate how education leaders can apply a critical lens to their generation and use of evidence. We explore how the strategic use of evidence is needed to advance the broader goal of fostering school change and improving school climate for all students.
