This brief summarizes lessons from "positive outlier" districts in California that have excelled at helping African American, Latino/a, and White students achieve at high levels on new assessments of academic standards in English language arts and mathematics, after accounting for students' socioeconomic status. Drawing on case studies of seven of these districts, this brief describes common elements related to their districts' high performance: a shared vision that prioritizes learning for every child; instructionally engaged leaders; a strong and stable educator workforce; collaborative professional learning; a developmental approach to instructional change; curriculum and assessment focused on deeper learning; use of evidence to inform teaching and learning; systemic supports for students' academic, social, and emotional needs; and engagement of families and communities.
