We use data from the Stanford Education Data Archive to describe district-level trends in average academic achievement between 2009 and 2019. Although on average school districts' test scores improved very modestly (by about 0.001 standard deviations per year), there is significant variation among districts. Moreover, we find that average test…

We investigate the predictive validity of teacher licensure tests using data from the Massachusetts Tests for Educator Licensure (MTEL). MTEL scores predict teachers' in-service performance ratings and contributions to student test scores (i.e., value added). We then explore whether these relationships vary for teacher candidates of color.…

Half of kindergarten teachers split children into higher and lower ability groups for reading or math. In national data, we predicted kindergarten ability group placement using linear and ordinal logistic regression with classroom fixed effects. In fall, test scores were the best predictors of group placement, but there was bias favoring girls,…

This study was designed to assess the effects of states' adoption of more rigorous standards as part of the current wave of standards-based reform on student achievement using comparative interrupted time series analyses based on state-level NAEP data from 1990 to 2017. Results show that the effects of adopting more rigorous standards on students'…

The transition to new assessments aligned to the Common Core State Standards was a significant turning point in the standards' implementation. Concerns about the transition led districts to suspend the use of value-added scores for evaluating teachers, but changes to other measures, such as classroom observations, were rare. Using data from the…

We draw on rich longitudinal data from one of the largest teacher education programs in Texas to examine the properties of rubric-based observational evaluations of preservice teachers (PSTs) during clinical teaching. Using a variance decomposition approach, we find that little of the variation in observation scores is attributable to actual…

This study examines the association between college-bound friends and college enrollment using restricted transcript data from the High School Longitudinal Study. Propensity score matching and school fixed effects models suggest that having close college-bound friends is positively associated with enrolling in college. However, Black and Latino…

The rapid expansion of school choice is restructuring public education in the United States. This study examines associations between charter and magnet school enrollment, White-Black and White-Hispanic segregation, and test score gaps at the district level from 2009 to 2015 in third to eighth grade using the Stanford Education Data Archive and…

Empirical research investigating the association between teacher pay incentives and student test scores has grown rapidly over the past decade. To integrate the findings from these studies and help inform the debate over teacher merit pay, this meta-analysis synthesizes effect sizes across 37 primary studies, 26 of which were conducted in the…

This article describes and evaluates a web-based coaching program designed to support teachers in implementing Common Core-aligned math instruction. Web-based coaching programs can be operated at relatively lower costs, are scalable, and make it more feasible to pair teachers with coaches who have expertise in their content area and grade level.…

Prior research shows that English learners (ELs) lag behind their peers in academic achievement and education attainment. The persisting gap is partly attributed to ELs' limited exposure to academic content. This article investigates the efficacy of a summer credit recovery program aimed at expanding high school newcomer ELs' access to academic…

In this experimental study, 20 multiple-choice test items from the Massachusetts Grade 5 science test were linguistically simplified, and original and simplified test items were administered to 310 English learners (ELs) and 1,580 non-ELs in four Massachusetts school districts. This study tested the hypothesis that specific linguistic features of…

Growing evidence suggests that preservice candidates receive better coaching and are more instructionally effective when they are mentored by more instructionally effective cooperating teachers (CTs). Yet teacher education program leaders indicate it can be difficult to recruit instructionally effective teachers to serve as CTs, in part because…

This study examined the effectiveness of participating in special education on the academic outcomes of students with disabilities. A sample of 575 students from a large, urban school district were followed longitudinally as they transitioned between general and special education to evaluate whether receiving special education services was…
