New Leaders developed the Transformational Leadership Framework (TLF) to pinpoint practices commonly found in schools that were significantly advancing student achievement and in what sequence principals and their teams implemented those practices to deliver consistent and equitable outcomes for students. The TLF is based on: (1) More than 100 site visits and case studies of schools that achieved dramatic gains; (2) An extensive review of available research on effective schools and leadership; and (3) The collective knowledge of the New Leaders staff and program participants. The Framework is organized to show how specific school leader actions have influenced and enabled schoolwide practices that have collectively yielded sustained improvements in student achievement.
