UCEA is pleased to announce the publication of the June Research Utilization Brief, School Principal as Leader. Improved student learning is the central focus for contemporary P-12 schools—and leadership is second only to teacher quality as the defining difference between schools that achieve high student performance and those that do not (Seashore Louis, Leithwood, Wahlstrom, & Anderson, 2010). For over a decade The Wallace Foundation has supported diverse efforts to improve leadership in public schools. In its January 2012 publication, The School Principal As Leader: Guiding Schools to Better Teaching and Learning, the Foundation presents a synthesis of lessons learned from more than 70 research reports and publications about school leadership. Five key functions performed by effective principals encapsulate the lessons learned from research and frame this Research Utilization Brief.
