We use a unique administrative database from the state of Florida to provide the first evidence that promotion and other job reassignments within school districts are systematically related to differences in teacher effectiveness in raising student achievement. We follow the career paths of a cohort of almost 25,000 classroom teachers during the 2001–02 school year for seven subsequent years. Our results confirm that effective teachers are more likely to become assistant principals or principals and less likely to be reassigned to a low-stakes teaching position. The tendency of highly effective teachers to continue teaching in high-stakes grades and subjects is strongest in schools receiving low ratings from the state’s school accountability system. Teachers entering the principal track experience a large increase in annual earnings, but the share of teachers promoted in this way is small enough that future compensation remains largely unrelated to effectiveness for teachers as a whole.

A growing number of American states and school districts require students to meet basic performance standards in core academic subjects at key transition points in order to be promoted to the next grade. We exploit a discontinuity in the probability of third grade retention under a Florida test-based promotion policy to study the causal effect of retention on student outcomes over time. Regression discontinuity estimates indicate large short-term gains in achievement among retained students and a sharp reduction in the probability of retention in subsequent years. The achievement gains from retention fade out gradually over time, however, and are statistically insignificant after six years. Despite this fade out, our results suggest that previous evidence that early retention leads to adverse academic outcomes is misleading due to unobserved differences between retained and promoted students. They also imply that the educational and opportunity costs associated with retaining a student in the early grades are substantially less than a full year of per pupil spending and foregone earnings.

We use nationally representative survey data and a research design that relies on contemporaneous within-student and within-teacher comparisons across two academic subjects to estimate how class size affects certain non-cognitive skills in middle school. Our results confirm that smaller 8th-grade classes are associated with improvements in several indicators of school engagement, with effect sizes ranging from 0.05 to 0.09 and smaller effects persisting two years later. Patterns of selection on observed traits and falsification exercises suggest that these results accurately identify (or possibly understate) the causal effects of smaller classes. Given the estimated earnings impact of these non-cognitive skills, the implied internal rate of return from an 8th-grade class-size reduction is 4.6 percent overall, but 7.9 percent in urban schools.

We use statewide administrative data from Florida to estimate the impact of attending public schools with different grade configurations on student achievement through grade 10. Based on an instrumental variable estimation strategy, we find that students moving from elementary to middle school suffer a sharp drop in student achievement in the transition year. These achievement drops persist through grade 10. We also find that middle school entry increases student absences and is associated with higher grade 10 dropout rates. Transitions to high school in grade nine cause a smaller one-time drop in achievement but do not alter students’ performance trajectories.

The Boston Teacher Residency is an innovative practice-based preparation program in which candidates work alongside a mentor teacher for a year before becoming a teacher of record in Boston Public Schools. We find that BTR graduates are more racially diverse than other BPS novices, more likely to teach math and science, and more likely to remain teaching in the district through year five. Initially, BTR graduates for whom value-added performance data are available are no more effective at raising student test scores than other novice teachers in English language arts and less effective in math. The effectiveness of BTR graduates in math improves rapidly over time, however, such that by their fourth and fifth years they out-perform veteran teachers. Simulations of the program’s overall impact through retention and effectiveness suggest that it is likely to improve student achievement in the district only modestly over the long run.

Conventional models of democratic accountability hinge on citizens’ ability to evaluate government performance accurately, yet there is little evidence on the degree to which citizen perceptions of the quality of government services correspond to actual service quality. Using nationally representative survey data, we find that citizens’ perceptions of the quality of specific public schools reflect publicly available information about the level of student achievement in those schools. The relationship between actual and perceived school quality is two to three times stronger for parents of school-age children, who have the most contact with schools and arguably the strongest incentive to be informed. However, this relationship does not differ by homeowner status or by respondents’ race, ethnicity, income, or education. A regression discontinuity analysis of an oversample of Florida residents confirms that public accountability systems can have a causal effect on citizen perceptions of service quality.

We examine earnings records for 90,000 classroom teachers employed by Florida public schools between the 2001–02 and 2006–07 school years, roughly 20,000 of whom left teaching during that time. Among grade 4–8 teachers leaving for other industries, a 1 standard deviation increase in estimated value-added to student achievement is associated with 6–9 percent higher earnings outside of teaching. The relationship between effectiveness and earnings is stronger in other industries than it is for the same teachers while in the classroom, suggesting that existing compensation systems do not account for the higher opportunity wages of effective teachers.
