Teacher professional development (PD) is among the most prominent levers used to improve teaching quality. The findings of research studies examining PD interventions are heterogeneous, with meta-analyses indicating mean positive impacts but also the existence of many ineffective programs. "Educational Researcher" has served as a…

How are teacher pension benefits funded? Under traditional plans, the full cost of career teachers' benefits far exceeds the contributions designated for them. The gap between the two has three pieces, which may (with some license) be mnemonically tagged the three R's of pension funding: "redistribution," "return," and…

We present data from the Schools and Staffing Survey and the National Teacher and Principal Survey to document the prevalence of instructional coaching programs (ICPs) and consider how ICPs are distributed by school level, urbanicity, new teachers in a school, student enrollment, school poverty levels, student achievement levels, and state. We…

We synthesize and critique federal fiscal policy during the Great Recession and COVID-19 pandemic. First, the amount of aid during both crises was inadequate to meet policy goals. Second, the mechanisms used to distribute funds were disconnected from policy goals and provided different levels of aid to districts with equivalent levels of economic…

Empirical growth benchmarks, as introduced by Hill, Bloom, Black, and Lipsey (2008), are a well-known way to contextualize effect sizes in education research. Past work on these benchmarks, both positive and negative, has largely avoided confronting the role of vertical scales, yet technical issues with vertical scales trouble the use of such…

In this article, we situate the relatively new wave of technology-enabled personalized learning platforms within the broader policy context of institutional accountability. Although many education technology innovations were developed in response to heightened accountability pressures, technology-enabled personalization introduces new…

Researchers commonly interpret effect sizes by applying benchmarks proposed by Jacob Cohen over a half century ago. However, effects that are small by Cohen's standards are large relative to the impacts of most field-based interventions. These benchmarks also fail to consider important differences in study features, program costs, and scalability.…

Despite the important role that replication studies play in building scientific evidence, recent reports show that few replications have been conducted in education. The goal of the current study was to examine how many efficacy and effectiveness research grants funded by the Institute of Education Sciences (IES) were replications, what types of…

This study identifies seven major trends in how states and districts are implementing college- and career-ready standards for general education students and for two special populations often the target of education policy--English language learners (ELLs) and students with disabilities (SWDs). We draw on state-representative teacher, principal,…

Both the Common Core State Standards (CCSS) and recent efforts to hold schools and teachers accountable have been hotly debated among practitioners, policymakers, and the public at large. Much of the debate centers on the merits and demerits of these initiatives and the general approach they represent to reforming teaching and learning. In this…

School-based evaluations of interventions are increasingly common in education research. Ideally, the results of these evaluations are used to make evidence-based policy decisions for students. However, it is difficult to make generalizations from these evaluations because the types of schools included in the studies are typically not selected…

The No Child Left Behind (NCLB) Act required states to adopt accountability systems measuring student proficiency on state-administered exams. The federal legislation contained several strict requirements for NCLB implementation, such as escalating student proficiency targets that reach 100% proficiency by 2014. But it also gave states…

A growing body of research has been documenting the pivotal role that philanthropic funding plays in advancing state and local charter school reform. However, there is little understanding of the geographic flow of these funding patterns and the market, policy, and organizational conditions that have concentrated funding in some clusters of states…

The Every Student Succeeds Act (ESSA) has generated considerable buzz in education circles and the general media. But how much has really changed, and what does this mean for states as they begin the process of implementing a new federal education law? In this article, we apply principal-agent theory to explore intergovernmental relations under…

An analysis was conducted of the What Works Clearinghouse (WWC) research evidence base on the effectiveness of replicable education interventions. Most interventions were found to have little or no support from technically adequate research studies, and intervention effect sizes were of questionable magnitude to meet education policy goals. These…
