Building on exploratory research (Braun et al., 2017), this study assessed how Core Leadership Practices (CLP), implemented through leadership development training, related to increased equity in student learning. Results confirmed a significant (p<0.05, medium to large effect sizes) positive increase in student learning for students who had been underserved (i.e., focal groups) and their peers at 93% of school data sets. Correlation analyses revealed a significant (p<0.05) relationship between the presence of the CLPs and increases in learning outcomes and educational equity. Findings suggest that development of shared leadership focused on continuous improvement can be used to increase equitable outcomes for students.
