This fifth annual High School Benchmarks Report provides the most updated data on high school graduates' college access, persistence, and completion outcomes. The report was designed with several features particularly tailored to secondary practitioners and policymakers. First, results presented in this report were based on the most up-to-date data on high school graduates' enrollment in a college or university, persistence from first to second year, and eventual completion of a postsecondary degree. Second, these outcomes were disaggregated by several high school characteristics, which include: income level, minority enrollment, and locale. Finally, in addition to providing the most recent benchmarking figures for high schools, the enrollment, persistence, and completion data are more complete than other data sources because it covers all postsecondary enrollments. Specifically, National Student Clearinghouse data captures all patterns of enrollment and completion, regardless of which postsecondary institution that students attend (e.g., out of state, private, public, or for-profit institutions) and regardless of transfers. This report enables those schools to compare their students' outcomes to those of other schools with similar characteristics and that also use the StudentTracker service. Using the results reported here, high schools and districts can place their own StudentTracker results into context with the college access, persistence, and completion rates for schools with similar student populations in similar locales across the country.
