Drawing on lessons learned from Wallace-funded research and state-district work in strengthening education leadership, the foundation has produced a paper that discusses the potential as well as the challenges of an emerging concept of leadership called a "Cohesive Leadership System." This cohesive leadership system holds potential for helping speed and make more permanent the advances being made in developing leadership that benefits the learning of all students, using a more systemwide, coordinated approach to state, district, and school-level policies and practices.
