Education is one of the largest sectors of the U.S. economy–yet scholars, educators, policymakers, and parents do not agree about what the money spent on education really buys. In particular, they do not agree on how much education improves children’s ability to learn or whether the things children learn in school truly improve their chances for success as adults. If schooling increases how much students know and what they know does pay off later, then it is important to ask what schools can do to increase students’ learning and earning. The essays in this book report estimates of the effects of learning on earnings and other life outcomes. They also examine whether particular aspects of schooling–such as the age at which children begin school, classroom size, and curriculum–or structural reform–such as national or statewide examinations or school choice–affect learning. Taken together, their findings suggest that liberals are correct in saying that more investment is needed in early education, that class sizes should be further reduced, and that challenging national or state standards should be established. But they also provide support for conservatives who ask for a more demanding curriculum and greater school choice.
