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…

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…

This paper reports on a study of collaborative group work in mathematics. Although collaborative group work is known as one of the important approaches in education, it is still uncertain how group thinking can be measured in various learning contexts. We used the Group Thinking Measure (GTM) test developed by [Wegerif, R., T. Fujita, J. Doney, J.…

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…

A compositional effect is when pupil attainment is associated with the characteristics of their peers, over and above their own individual characteristics. Pupils at academically selective schools, for example, tend to out-perform similar-ability pupils who are educated with mixed-ability peers. Previous methodological studies however have shown…

Because the pandemic exacerbated chronic absenteeism in many parts of the country, the need to understand how schools can improve student attendance has never been greater. Accordingly, this study breaks new ground by examining high schools' contributions to attendance after accounting for individual students' prior absenteeism and other…

Using two states' grades 3 through 8 state assessment databases, this study documents the extent to which students were assigned testing accommodations for ELA or mathematics in only one of two consecutive years. The percentage of students with disabilities who were assigned accommodations in the current year only or in the prior year only in a…

Background: Value-added modeling (VAM) has been used to rank teachers and assess teacher and school quality. The apparent relationship between value-added teacher rankings and gains in student performance provide a foundation for the view that the contribution of teachers to student performance is the largest factor influencing student…

With more rigorous standards and testing at the forefront of educational reform across the nation, the rural school district in this study developed a strategic compensation plan with bonus pay based on student test scores as a teacher success incentive. A causal-comparative study was conducted to examine the effect of teacher merit pay levels on…

Objectives: It has been suggested that students are healthier in schools where more students are committed to school. Previous research has examined this only using a proxy measure of value-added education (a measure of whether school-level attendance and attainment are higher than predicted by students' social profile), finding associations with…

Papay (2011) noticed that teacher value-added measures (VAMs) from a statistical model using the most common pre/post testing timeframe--current-year spring relative to previous spring (SS)--are essentially unrelated to those same teachers' VAMs when instead using next-fall relative to current-fall (FF). This is concerning since this choice--made…

Disrupted schooling can heavily impact the amount of education pupils receive. Starting in early June of 2011 a huge social outburst of pupil protests, walk-outs, riots and school occupations called the Chilean Winter caused more than 8 million of lost school days. Within a matter of days, riots reached the national level with hundreds of…

Value-added measures of educational progress have been used by education researchers and policy-makers to assess the performance of teachers and schools, contributing to performance-related pay and position in school league tables. They are designed to control for all underlying differences between pupils and should therefore provide unbiased…

This study examines the accuracy of performance ratings from the Framework for Leadership (FFL), Pennsylvania's tool for evaluating the leadership practices of principals and assistant principals. The study analyzed four key properties of the FFL: score variation, internal consistency, year-to-year stability, and concurrent validity. Score…

This "Stated Briefly" report is a companion piece that summarizes the results of another report of the same name. This study examines the accuracy of performance ratings from the Framework for Leadership (FFL), Pennsylvania's tool for evaluating the leadership practices of principals and assistant principals. The study analyzed four key…
