Student surveys are widely used to evaluate university teaching and increasingly adopted at the K-12 level, although there remains considerable debate about what they measure. Much disagreement focuses on the well-documented correlation between student grades and their evaluations of instructors. Using individual-level data from 19,000 evaluations of 700 course sections at a flagship public university, we leverage both within-course and within-student variation to rule out popular explanations for this correlation. Specifically, we show that the relationship cannot be explained by instructional quality, workload, grading stringency, or student sorting into courses. Instead, student grade satisfaction -- regardless of the underlying cause of the grades -- appears to be an important driver of course evaluations. We also present results from a randomized intervention with potential to reduce the magnitude of the association by reminding students to focus on relevant teaching and learning considerations and by increasing the salience of the stakes attached to evaluations for instructor careers. However, these prove ineffective in muting the relationship between grades and student scores.
Political scientists have largely overlooked the democratic challenges inherent in the governance of U.S. public education—despite profound implications for educational delivery and, ultimately, social mobility and economic growth. In this study, we consider whether the interests of adult voters who elect school boards in each community are likely to be aligned with the educational needs of local students. Specifically, we compare voters and students in four states on several policy-relevant dimensions. Using official voter turnout records and rich microtargeting data, we document considerable demographic differences between voters who participate in school board elections and the students attending the schools that boards oversee. These gaps are most pronounced in majority nonwhite jurisdictions and school districts with the largest racial achievement gaps. Our novel analysis provides important context for understanding the political pressures facing school boards and their likely role in perpetuating educational and, ultimately, societal inequality.
We employ a regression discontinuity design leveraging close school board elections to investigate how the racial and ethnic composition of California school boards affects school district administration and student achievement. We find some evidence that increases in minority representation lead to cumulative achievement gains of approximately 0.1 standard deviations among minority students by the sixth post-election year. These gains do not come at the expense of white students' academic performance, which also appears to improve. Turning to the policy mechanisms that may explain these effects, we find that an increase in minority representation leads to greater capital funding and an increase in the proportion of district principals who are non-white. We find no significant effects of minority representation on school segregation, the reclassification of English Language Learners, or teacher staffing.
We use close tax elections to estimate the impact of school district funding increases on operational spending and student outcomes across seven states. Districts with passing levies directed new revenue toward support services and instructor salaries but did not increase teacher staffing levels. These districts eventually realized gains in student achievement and attainment. Our preferred estimates imply that increasing operational spending by $1,000 per pupil increased test scores by approximately 0.15 of a standard deviation and graduation rates by approximately 9 percentage points. There is some evidence of diminishing returns, as these effects are driven by districts below the median in spending per pupil. Based on research linking academic outcomes to earnings, we conclude that these spending increases were likely cost-effective.
Governments around the world have privatized public services in the name of efficiency and citizen empowerment, but some argue that privatization could also affect citizen participation in democratic governance. We explore this possibility by estimating the impact of charter schools (which are publicly funded but privately operated) on school district elections. The analysis indicates that the enrollment of district students in charter schools reduced the number of votes cast in district school board contests and, correspondingly, reduced turnout in the odd-year elections in which those contests are held. This impact is concentrated in districts that serve low-achieving, impoverished, and minority students, leading to a modest decline in the share of voters in those districts who are black and who have children. There is little evidence that charter school expansion affected the outcomes of school board elections or turnout in other elections
