U.S High School Graduation Rates: Patterns and Explanations

THIS REPORT surveys the evidence on patterns in U.S. high school graduation rates over the period 1970-2010 and report the results of new research conducted to fill in holes in the evidence.

THIS REPORT begin sby pointing out the strengths and limitations of existing data sources.

THIS REPORT then describes six striking patterns in graduation rates. They include stagnation over the last three decades of the twentieth century, significant race-, income-, and gender-based gaps, and significant increases in graduation rates over the first decade of the twenty-first century, especially among blacks and Hispanics.

The author then describes the models economists use to explain the decisions of individuals to invest in schooling, and examine the extent to which the parameters of the models explain recent patterns in graduation rates.

THIS REPORT finds that increases in the nonmonetary costs of completing high school and the increasing availability of the GED credential help to explain stagnation in the face of substantial gaps between the wages of high school graduates and school dropouts.

THIS REPORT points out that there are several hypotheses, but to date, very little evidence to explain the increases in high school graduation rates over the first decade of the twenty-first century.

THIS REPORT concludes by reviewing the evidence on effective strategies to increase high school graduation rates, and explaining why the causal evidence is quite modest.
