Starting in 2009, the U.S. public education system undertook a massive effort to institute new high-stakes teacher evaluation systems. We examine the effects of these reforms on student achievement and attainment at a national scale by exploiting the staggered timing of implementation across states. We find precisely estimated null effects, on average, that rule out impacts as small as 1.5 percent of a standard deviation for achievement and 1 percentage point for high school graduation and college enrollment. We also find little evidence of heterogeneous effects across an index measuring system design rigor, specific design features, and district characteristics.
Economic downturns can cause major funding shortfalls for U.S. public schools, often forcing districts to make difficult budget cuts including teacher layoffs. In this brief, we synthesize the empirical literature on the widespread teacher layoffs caused by the Great Recession. Studies find that teacher layoffs harmed student achievement and were inequitably distributed across schools, teachers, and students. Research suggests that specific elements of the layoff process can exacerbate these negative effects. Seniority-based policies disproportionately concentrate layoffs among teachers of color who are more likely to be early career teachers. These “last-in first-out” policies also disproportionately affect disadvantaged students because these students are more likely to be taught by early career teachers. The common practice of widely distributing pink slips warning about a potential job loss also appears to increase teacher churn and negatively impact teacher performance. Drawing on this evidence, we outline a set of policy recommendations to minimize the need for teacher layoffs during economic downturns and ensure that the burden of any unavoidable job cuts does not continue to be borne by students of color and students from low-income backgrounds.
Local school boards have primary authority for running educational systems in the U.S. but little is known empirically about the merits of this arrangement. State takeovers of struggling districts represent a rare alternative form of educational governance and have become an increasingly common response to low performance. However, limited research explores whether this effectively improves student outcomes. We track all takeovers nationwide from the late 1980s, when the first takeovers occurred, through 2016 and describe takeover districts. While these districts are low performing, we find academic performance plays less of a role in predicting takeover for districts serving larger concentrations of African American students. We then use a new data source allowing for cross-state comparisons of student outcomes to estimate the effect of takeovers that occurred between 2011 and 2016. On average, we find no evidence that takeover generates academic benefits. Takeover appears to be disruptive in the early years of takeover, particularly to English Language Arts achievement, although the longer-term effects are less clear. We also observe considerable heterogeneity of effects across districts. Takeovers were least effective in districts with higher baseline achievement and least harmful in majority Latinx communities. Leaders should be cautious about using takeover without considering local context and a better understanding of why some takeovers are more effective than others.
Policymakers have sought to increase the rigor of content standards since the 1990s. However, the literature examining the effects of reforms to content standards on student outcomes is still developing. This study examines the extent to which the Common Core State Content Standards (CC) affected student achievement and the size of achievement gaps. To identify the effect of CC I compare early implementors of the CC to late implementors of the CC in a Difference-in-Differences framework. I conducted a document analysis to measure preparation for and implementation of the CC standards, which I merge together with the National Assessment of Educational Progress student-level data. I then exploit variation in the timing of state implementation of the CC to identify its effect on students overall and academically vulnerable groups. I find that the CC has a positive effect on math scores in 4th and 8th grade, but not in reading. The CC had a large positive effect on economically advantaged students, but a null effect for economically disadvantaged students. Demanding better results without addressing the structural issues burdening economically disadvantaged students may result in unintended consequences.
