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…

This quantitative study investigated whether teachers' perceptions on principal leadership, teacher leadership, student discipline, and teacher retention exhibited significant differences based on two school conditions: school growth status and school performance grade in low-performing elementary schools across North Carolina. The study analyzed…

The number of low-performing schools has drastically increased since COVID-19. During the 2018-2019 school year, there were 488 low-performing schools (North Carolina Department of Public Instruction, 2024). The number increased to 736 schools during the 2023- 2024 school year, a 50.8% increase (North Carolina Department of Public Instruction,…

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…

This study compares the estimated grammar school effect in different regression models, and explains why previous evidence of the effectiveness of grammar school is mixed. Like most studies of school effectiveness evaluation, previous research on grammar school effect usually applies regression to control for confounding between-school factors and…

Although existing research suggests that students benefit on a range of outcomes when they enroll in early algebra classes, policy efforts that accelerate algebra enrollment for large numbers of students often have negative effects. Explanations for this apparent contradiction often emphasize the potential role of teacher and peer effects, which…

Background: Since the COVID-19 pandemic, American students have demonstrated substantial losses in achievement (Amplify, 2021; Domingue et al., 2021; Dorn et al., 2020; Storey & Zhang, 2023), while chronic absenteeism doubled after the pandemic, with the largest increase among low-income students (Chang et al., 2022; Dorn et al., 2021). Among…

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…

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…

There is an enduring issue on whether student- and school-level covariates should be included in value-added school effects models, in addition to prior achievement. Proponents argue that the addition of covariates allows fairer comparisons of schools, whereas opponents argue that it excuses poorly performing schools and obscures policy-relevant…

Homework has traditionally been considered positive for students' academic achievement, to the extent that it makes children more responsible while learning. Nevertheless, making students do a large amount of homework has been one of the most criticised practices in recent years. Parental associations have long held the view that Spanish…

Education systems focus on issues related to school effects and differences. School effects are used as a basis for accountability in various countries including China. This study investigated the stability and cross-disciplinary consistency of value-added estimates based on student scores in selected schools in a city in central China. The…

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…
