Book excerpt: In this groundbreaking book, co-editors Pedro Noguera and Jean Yonemura Wing, and their collaborators investigated the dynamics of race and achievement at Berkeley High School–a large public high school that the New York Times called "the most integrated high school in America." Berkeley's diverse student population clearly illustrates the "achievement gap" phenomenon in our schools. Unfinished Business brings to light the hidden inequities of schools–where cultural attitudes, academic tracking, curricular access, and after-school activities serve as sorting mechanisms that set students on paths of success or failure.
