Educational interventions are often evaluated and compared on the basis of their impacts on test scores. Decades of research have produced two empirical regularities: interventions in later grades tend to have smaller effects than the same interventions in earlier grades, and the test score...

President Obama's "Preschool for All" initiative calls for dramatic increases in the number of 4 year olds enrolled in public preschool programs and in the quality of these programs nationwide. The proposed program shares many characteristics with the universal preschools that have been offered...

Is the Armed Forces Qualifying Test (AFQT) a measure of achievement or ability? The answer to this question is critical for drawing inferences from studies in which it is employed. In this paper, we test for a relationship between schooling and AFQT performance in the NLSY 79 by comparing...

It is widely documented that U.S. students score below their OECD counterparts on international achievement tests, but it is less commonly known that ultimately, U.S. native adults catch up. In this paper, we explore institutional explanations for differences in the evolution of literacy over...

The Voting Rights Act of 1965 (VRA) has been called one of the most effective pieces of civil rights legislation in U.S. history, having generated dramatic increases in black voter registration across the South. We show that the expansion of black voting rights in some southern states brought...

Beginning in the mid-1960s, many state governments, particularly in the South and West, began to subsidize kindergartens for the first time. These initiatives generated wide variation across states over time in the supply of seats for five year olds in public schools. This paper uses the...

We estimate the effects of having more mature peers using data from an experiment where children of the same age were randomly assigned to different kindergarten classrooms. Exploiting this experimental variation in conjunction with variation in expected kindergarten entry age to account for...

This paper examines how a large conditional grants program influenced school desegregation in the American South. Exploiting newly collected archival data and quasi-experimental variation in potential per-pupil federal grants, we show that school districts with more at risk in 1966 were more...

An extensive literature debates the causes and consequences of the desegregation of American schools in the twentieth century. Despite the social importance of desegregation and the magnitude of the literature, we have lacked a comprehensive accounting of the basic facts of school desegregation....

In the 1960s and 1970s, many states introduced grants for school districts offering kindergarten programs. This paper exploits the staggered timing of these initiatives to estimate the long-term effects of a large public investment in universal early education. I find that white children aged...
