Leaders of successful high schools, middle grades schools and technology centers are strengthening their skills and involving the entire school in plans to raise student achievement. The best school leaders establish an environment of continuous progress in which teachers and leaders work together to upgrade curriculum and instruction, examine data to identify weaknesses in school and classroom practices, and develop and implement plans to increase the vitality of school reform. This newsletter contains four sections of best practices from "High Schools That Work" ("HSTW"), "Making Middle Grades Work" ("MMGW") and "Technology Centers That Work" ("TCTW") sites that illustrate the importance of: (1) building-level leadership, (2) distributive leadership structures, (3) leadership for continuous improvement, and (4) leadership for effective professional development. [This newsletter of "best practices" in implementing the "High Schools That Work" ("HSTW"), "Making Middle Grades Work" ("MMGW") and "Technology Centers That Work" ("TCTW") school improvement models is based on presentations at the 23rd Annual "HSTW" Staff Development Conference in Atlanta, Georgia, in July 2009.]
