Globally, the private school share of enrollment increased from about 14 percent in 2000 to about 18 percent in 2019. We estimate the systemic effect of private enrollment share on learning outcomes. Estimates of the systemic effect of private school enrollment capture any competitive effects as well as any differences between public and private…

Has the achievement of U.S. students improved over the past half century? Have gaps between racial, ethnic, and socioeconomic groups widened or narrowed? These and similar questions provoke near-constant conversation. But answers are uncertain, partly because research to date has yielded inconsistent findings. In this article, the authors bring…

Principals (policy makers) have debated the progress in U.S. student performance for a half century or more. Informing these conversations, survey agents have administered seven million psychometrically linked tests in math and reading in 160 waves to national probability samples of selected cohorts born between 1954 and 2007. This study is the…

The reading literacy skills of Australian adolescents, as measured in successive PISA waves, have declined since 2000. Literacy achievement is not low by international standards, but it is lower in Australia than it is in Anglophone countries with which we compare ourselves, e.g. Canada. Using PISA 2018 and PIRLS 2021 data, we investigated both…

Gender differences in math-related professional achievements have been identified as a worldwide problem. Academic achievement assessments, however, have repeatedly revealed gender similarities. The observed gender similarity might be due to biased assessments that heavily rely on reading skills, which favors girls. The current study analyzed 29…

International large-scale assessments (ILSAs) are one of the most important tools policymakers and other educational stakeholders have to inform evidence based decision making for educational reform. Despite this, and the widespread use of ILSA data, results are sometimes misunderstood or misinterpreted. Here, we offer a brief guide to ILSAs and…

Gender differences in reading seem to increase throughout schooling and then decrease or even disappear with age, but the reasons for this are unclear. In this study, we explore whether differences in the way "reading literacy" is operationalised can add to our understanding of varying gender differences in international large-scale…

It is well-documented that academic achievement is associated with students' self-perceptions of their academic abilities, that is, their academic self-concepts. However, low-achieving students may apply self-protective strategies to maintain a favorable academic self-concept when evaluating their academic abilities. Consequently, the relation…

Australia and New Zealand have participated in the Organisation for Economic Co-operation and Development's Programme for International Student Assessment since 2000. Reading literacy was the main focus of the Programme for International Student Assessment in 2000, and at that time both countries' students generally performed well above the…

Background: While existing evidence strongly suggests that immigrant students underperform relative to their native counterparts on measures of mathematics, science, and reading, country-level analyses assessing the homogeneity of the immigrant achievement gap across different factors have not been systematically conducted. Beyond finding a…

Education is recognised across the Gulf Cooperation Council (GCC) as a moral imperative and a strategic priority to secure future prosperity and human flourishing. Policymakers have set ambitious targets to join the ranks of the best performing education systems in the world in order to deliver economic success and secure a place on the world…

This article outlines the complexity of reading with understanding, what is required for full and deep comprehension, the state of affairs with regard to reading comprehension in developed countries, possible etiologies for low performances, and suggestions for instruction in specific skills and strategies to improve students' demonstrated…

Each country's education system is intricate and unique, underpinned with different policies and priorities. International Large Scale Assessments (ILSAs) provide valuable insights into how a country's education system is performing. These studies gather in-depth contextual information about systems, schools, teachers and students; and explore the…

Background: Political devolution occurred in the UK in 1998-99, following many years in which some degree of policy administration had been devolved to the four nations. Since devolution, all four countries of the UK have pursued increasingly divergent education policies. This is true in England in particular, where diversity, choice and…

One of the major imperatives behind the comprehensivisation of secondary education was the belief that postponing the age at which students are tracked in different educational routes would mitigate the effect of social background on educational outcomes. Comparative investigations of large-scale international student achievement tests in…
