The test score gap between blacks and whites - on vocabulary, reading, and math tests, as well as on tests that claim to measure scholastic aptitude and intelligence - is large enough to have far-reaching social and economic consequences. In their introduction to this book, Christopher Jencks and Meredith Phillips argue that eliminating the disparity would dramatically reduce economic and educational inequality between blacks and whites. Indeed, they think that closing the gap would do more to promote racial equality than any other strategy now under serious discussion. The book offers a comprehensive look at the factors that contribute to the test score gap and discusses options for substantially reducing it.
