Using a model successfully developed by the Harvard Graduate School of Education and successfully applied in industry, Superintendent P.K. Diffenbaugh of the Monterey Peninsula Unified led an effort to improve school and district culture by applying the latest research on adult development to employees’ lives, relationships, and professional practices. The report asserts that creating a healthy culture, which includes creating a strong sense of community, establishing high levels of trust and the ability to give and receive feedback, can produce significant gains in student achievement. This 10-page case report describes the approach, assesses its impact and its implications for the education sector. Co-author Arun Ramanathan is the CEO of PivotLearning, an Oakland-based nonprofit that guided the effort through a grant from the Silver Giving Foundation.
