How can we bolster the academic success of low achieving students and provide a more egalitarian classroom setting? This book describes the process of 'untracking', an educational reform effort that has prepared students from low income, linguistic, and ethnic minority backgrounds for college. Untracking offers all students the same academically-demanding curriculum while varying the amount of institutional support they receive. Helpful institutional 'scaffolds' teach the hidden curriculum of the school, allowing students to develop an academic identity and build bridges between high school and college. There have been many plans and attempts to reform schools, but few detailed investigations of such efforts. This book is a highly readable account of a successful school reform effort. It provides systematic research results concerning the educational and social consequences of untracking previously low achieving students.
