This long-awaited, solution-oriented book helps readers understand how inequality is organized in our public educational system. A four-component developmental model provides a policy-oriented framework that takes into account how children are socialized in and out of schools. Given an educational system that produces unequal opportunities for student learning, closing the gap requires thinking out of a box and the current conglomeration of social and economic policies. A multi-level strategy that aims for all to be educated at grade-level through a coordinated national strategy is presented to eliminate educational inequality. This is a «must read», controversial book that offers educators and policy-makers a fundamental understanding of how the achievement gap can be eliminated at the population level.
