This handbook is the result of more than 2 years' deliberations by The Commission on the Restructuring of the American High School. The Commission emerged from a partnership of the National Association of Secondary School Principals (NASSP) and the Carnegie Foundation for the Advancement of Teaching. The report focuses on revitalizing education for all students and points to what is needed for the 21st-century high school. Eighty recommendations are offered in three sections: priorities for renewal; web of support; and leadership. They encompass the scope of programs and activities affecting high school students, including socialization, basic skills, electronic learning, assessment and accountability, links to higher education, school leadership, the classroom, and business-school partnerships. The report represents the commissioners' recommendations to ensure that every student receives a complete, student-centered, and high quality education. (Contains 123 endnotes.) (LMI)
