The Winter Hill Community Innovation School in Somerville, Massachusetts and the Paul Revere Innovation School in Revere, Massachusetts, winners of the 2017 Pozen Prize for Innovative Schools--excel in attending to the social, emotional, and intellectual needs of all students in the diverse communities they serve. Leveraging autonomy to strengthen teacher collaboration and community engagement, these two Massachusetts innovation schools created child-centered learning environments. With staff united by a relentless focus on supporting the whole child, the Winter Hill and the Paul Revere underwent rapid school improvement by supporting students' social, emotional, and intellectual needs. This case study describes the key practices the Winter Hill and Paul Revere schools used to meet student learning needs and the influence school-based decision-making can have on accelerating school improvement.
