June 2013Race and College Success: Evidence from Missouri
with Peter Arcidiacono: w19188
Conditional on enrollment, African American students are substantially less likely to graduate from 4-year public universities than white students. Using administrative micro data from Missouri, we decompose the graduation gap between African Americans and whites into four factors: (1) racial differences in how students sort to universities, (2) racial differences in how students sort to initial majors, (3) racial differences in school quality prior to entry, and (4) racial differences in other observed pre-entry skills. Pre-entry skills explain 65 and 86 percent of the gap for women and men respectively. A small role is found for differential sorting into college, particularly for women, and this is driven by African Americans being disproportionately represented at urban schools and the ...

March 2009Value-Added to What? How a Ceiling in the Testing Instrument Influences Value-Added Estimation
with Julian Betts: w14778
Value-added measures of teacher quality may be sensitive to the quantitative properties of the student tests upon which they are based. This paper focuses on the sensitivity of value-added to test-score-ceiling effects. Test-score ceilings are increasingly common in testing instruments across the country as education policy continues to emphasize proficiency-based reform. Encouragingly, we show that over a wide range of test-score-ceiling severity, teachers' value-added estimates are only negligibly influenced by ceiling effects. However, as ceiling conditions approach those found in minimum-competency testing environments, value-added results are significantly altered. We suggest a simple statistical check for ceiling effects.
