This report is the first of a series of lessons learned from the Transatlantic School Innovation Alliance. The goal of this partnership is to improve teaching, learning, and educational leadership by creating a peer network of principals and practitioners in urban secondary schools in the United States and the United Kingdom. The report examines how policy shapes practice in these collaborative networks, which benefit educators by allowing them to share knowledge and best practices with their peers in other schools and cities, as well as internationally.
