The Condition of Education in the Commonwealth Action Guide presents an overview of the current policy landscape and context in areas of need, along with suggested program steps for bringing successful practices to scale. The Action Guide and the larger Condition of Education in the Commonwealth project provides a common foundation for more informed action statewide, building bridges between what we know how to do and what we aspire to achieve for all students. A number of promising reform activities, including several highlighted in the 2015 Condition of Education Action Guide, emphasize partnerships between schools and community-based organizations to supplement a broader range of student learning needs. As current patterns in student performance are examined and one considers where, as a state, Massachusetts has the greatest opportunity to improve outcomes, social-emotional learning emerges as a clear priority. In this year's Condition of Education Action Guide, the Rennie Center for Education Research & Policy explores the critical role social-emotional learning plays at several stages of the schooling pipeline, noting where the state has made progress and how Massachusetts leaders can support a more comprehensive and research-based vision for social-emotional learning for all educators, students, and their families.
