Worldwide, the Programme for International Student Assessment (PISA) has emerged as a valid and reliable benchmark for assessing students' performance and for gaining significant influence over educational policy and decision-making. Since 2001, Qatar has engaged in massive educational reform, with high expectations for improving students'…

Large-scale international achievement studies such as PISA have been widely used to study how educational inequality compares across countries. Yet the various different biases that may affect these estimates are often not considered or are poorly understood. In this paper we draw upon the total survey error framework to provide a case study of…

Throughout the years, United States education reform has sought to target the most disadvantaged students. Nonetheless, during this same period, proficiency rate disparities seem to have emerged among student subgroups. This study was designed to find ways for school districts to begin closing the achievement gaps between student subgroups,…

We analyse the PISA-reported convergence in the performance of private and public schools in Portugal. When PISA sampling weights are used, the number of students enrolled in those types of schools and specific grades/tracks of study differs significantly from official population figures. To account for those differences, we apply a…

Research indicates that the achievement gap in reading between typical and dyslexic readers is already evident in first grade and persists through adolescence. However, it is not known whether this reading gap persists into adult life. In this report we use an epidemiologic sample of 312 children (typical readers = 246; dyslexic readers = 66),…

This quantitative quasi-experimental study was completed to identify the impact the Success for All: Reading Edge (SFA) program had on student achievement at a Title I middle school. To improve literacy and student achievement in schools, scripted reading programs were created. With the popularity of these programs, research needs to be completed…

Cross-national studies on socioeconomic status (SES) achievement gaps have focused on the size of the gap and given less attention to where in the SES distribution the achievement gap tends to be relatively large within a society, and whether this location varies across countries. We estimate the relative size of achievement gaps between students…

Many factors contribute to the achievement gap in the U.S. As an intervention to help narrow the gap, tutoring presents a potentially powerful solution. Decades of research suggest that tutoring is an effective, evidence-based approach to improve student success, with effect sizes ranging from 0.4. to 2.0. As many school systems in the U.S. move…

Reducing the socio-economic achievement gap is a key goal of education policy internationally. Since 2017, the stated intention in Ireland is to use the Pobal HP Deprivation Index to identify schools serving high proportions of disadvantaged students. In spite of this, little published research has compared the performance of the HP index to…

This study explored a relationship between internet access and literacy using quantitative data regarding students' reading performance. Data used in this study included reading scores provided by the Program for International Student Assessment (PISA) and the internet access data made available by the Organization for Economic Co-operation and…

In all years of the Program for International Student Assessment (PISA) in primary mathematics education, Finland ranked in the lower places (44-61) in the dispersion index (the difference in scores between the 95th percentile and the 5th percentile), while Israel ranked in the upper places (1-3) in the same index. In the last PISA test, Israel…

Improving schooling by reducing achievement gaps based on family background has been on the agenda of school governance worldwide for more than three decades. International benchmarking like the OECD's Programme for International Student Assessment (PISA) is used to find models of best practice in effective school governance. Enlarging school…

The purpose of this study was to determine if there are significant differences in the English/Language Arts proficiency scores of elementary school students who attend a traditional public school or one of two types of turnaround schools in a large metropolitan school district in the southern region of the United States. The goal was to determine…

Widening achievement gaps driven by socioeconomic disparity have become a global concern. Yet, few studies have been able to track the changes and developments of socioeconomic-achievement gaps (SES-achievement gaps henceforward) across time. Using PISA data from 2003 to 2018, we estimated family SES-achievement gaps in seven Asian education…

The present study investigated whether the socioeconomic achievement gap in academically at-risk students varied as a function of students' perceived classroom goal structures. We hypothesized that low socioeconomic status (SES) students would be more susceptible to the various classroom goal structures. Specifically, we hypothesized that high…
