As a part of the Wallace Foundation’s Principal Pipeline Initiative, GLISI helped participating principals prepare a guide based on their own best practices, as well as those from experts in the field, to create a roadmap by principals for principals with concrete strategies and recommendations for focusing principals’ time on instructional leadership for the benefit of the children and communities they serve. It provides direction and artifacts for use by district leaders and principals to develop teams within schools who are effective at delivering high quality instruction for all students
