The School-University Research Network (SURN) Principal Academy at the College of William & Mary in Williamsburg, Virginia, has a mission to build a leadership development program that increases principals' instructional knowledge and develops mentor principals to sustain the program. The academy is designed to connect and empower principals to improve their instructional leadership and relationship building skills. Such professional learning results in high impact teaching and student learning by: (1) Developing knowledge of effective teaching and learning strategies; (2) Increasing formative feedback that supports teacher reflection and distributive leadership in professional learning communities; (3) Providing multi-year cohort support for participating principals; (4) Recruiting a cadre of expert, veteran principals to mentor early-career principals; and (5) Disseminating project findings through digital/electronic media and division, regional, state, and international conferences. This article describes the two-year program which consists of professional learning days, intersession activities, coaching, and mentors using John Hattie's Visible Learning (2009) as one of the research foundations and leadership techniques. Four leadership actions that drive the SURN Principal Academy are: (1) Build relationships and a community of practice; (2) Observe for and talk more about learning than teaching; (3) Provide targeted feedback; and (4) Empower stakeholders to assess impact. John Fahey provides a Superintendent's perspective after three principals in his school district participated in the SURN Academy; and Rachel Ball offers a principal's outlook on her own participation in the academy. An observation tool to record occurrences of high- and low-yield practices is also included.
