August 16, 2012 – Public Impact’s Bryan Hassel teams up with Celine Coggins of Teach Plus in this Commentary for Education Week. They argue that school reform efforts that do not expand the impact—and number—of excellent teachers are bound to fall short. Schools must extend the reach of excellent teachers to more students, couple teacher collaboration with teacher leadership, and empower top teachers to shape school culture. Meanwhile, policymakers must clear away the policies that holds great teachers back and boost the national will to put an excellent teacher in every classroom.
