Shines a spotlight on "excellence gaps” - the achievement gaps among subgroups of students performing at the highest levels of achievement. The authors argue that these significant gaps reflect the existence of a persistent talent underclass in the United States among African American, Hispanic, Native American, and poor students, resulting in an incalculable loss of potential.
