Measuring teacher effectiveness has been debated and studied for numerous years. While some progress has been made, consensus has yet to be reached regarding what it means to be an effective teacher and how to measure effectiveness. This study uses administrative data from North Carolina to assess the relationship between school principal…

We identify systematic differences in ninth-grade teachers' effects on students' course grades in their class (ninth-grade grade value-add), their persistent effects on students' grades in the same subject of the next grade (tenth-grade grade value-add, representing effectiveness at academic preparation), and mismatch between the grades they give…

The effect of remote learning on student performance has been a frequent topic of research and discussion in the aftermath of the COVID-19 pandemic, yet little is known about the impact of remote instruction on the performance of teachers. This study documents how relative effectiveness of teachers changed when moving from in-person to remote…

School accountability systems increasingly hold schools to account for their performances using value-added models purporting to measure the effects of schools on student learning. The most common approach is to fit a linear regression of student current achievement on student prior achievement, where the school effects are the school means of the…

There is no final consensus regarding which covariates should be used (in addition to prior achievement) when estimating value-added (VA) scores to evaluate a school's effectiveness. Therefore, we examined the sensitivity of evaluations of schools' effectiveness in math and language achievement to covariate selection in the applied VA model. Four…

Using rich panel data from Pakistan, we compute test score based measures of quality (School Value-Addeds or SVAs) for more than 800 schools across 112 villages and verify that they are valid and unbiased. With the SVA measures, we then document three striking features of the schooling environment. First, there is substantial within-village…

Inappropriate treatment of missing data may introduce bias into the value-added estimation. We consider a commonly used value-added model (VAM), which includes the past student test score as a covariate. We formulate a joint model of student achievement and missing data, in which the probability of observing a test score depends on observing the…

The use of student learning objectives (SLOs) as part of teacher performance systems has gained traction quickly in the United States, yet little is known about how teachers select specific students' learning goals. When teachers are evaluated--and sometimes compensated--based on whether their students meet the very objectives the teachers set at…

In this paper, we measure the contribution of an additional year of schooling on skills acquisition for a cohort of young adults in Madagascar. We estimate a value-added model of learning achievement that includes test scores measured at adolescence, thereby reducing the potential for omitted variable bias. We demonstrate that schooling increases…

When the COVID-19 pandemic hit the U.S. last spring, schools nationwide shut their doors and states cancelled annual standardized tests. Now federal and state policymakers are debating whether to cancel testing again in 2021. One factor they should consider is whether a two-year gap in testing will make it impossible to measure student-level…

For this study, researchers critically reviewed documents pertaining to the highest profile of the 15 teacher evaluation lawsuits that occurred throughout the U.S. as pertaining to the use of student test scores to evaluate teachers. In New Mexico, teacher plaintiffs contested how they were being evaluated and held accountable using a homegrown…

We use teacher candidate test scores on the Massachusetts Tests for Educator Licensure (MTEL), linked to student and teacher outcomes in the state, to investigate the predictive validity of these teacher licensure tests. We find that MTEL scores are positive and statistically significant predictors of teachers' in-service performance ratings and…

For decades, school districts across the Nation have been pressured to close the achievement gap among students and have been held accountable for student outcomes. According to past researchers, there is a need to revise completely the teacher evaluation practices used in the 1980s and 1990s to better measure teacher effectiveness. More recently,…

Value-added assessment is designed to measure teacher contributions to student achievement in order to promote effective teaching (Battelle for Kids, 2011b; Darling-Hammond et al., 2012; Lee, 2011). When value-added assessment is used, research indicates that in some cases effective teaching is promoted, but in other cases it is not…

We examine the relationship between absenteeism and achievement since the onset of COVID-19. Applying first-differences models to North Carolina administrative data, we estimate that each absence was associated with a 0.0032 standard deviation (SD) decline in math achievement in 2022-23. As students averaged 3.3 more absences in 2022-23 than…
