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…

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…

We investigated effects of tracking students into higher, more academic, and lower, less academic, school types immediately after primary school (early tracking) instead of having a comprehensive secondary school system (late tracking) on school gender segregation and gender gaps in achievement outcomes. We assumed that, in early tracking…

An extensive body of research exists on the background characteristics that predict learner achievement. However, in South Africa, little attention has been paid to the level of educational aspirations and the factors that shape the level of aspirations. Using a bio-ecological systems theory of development, we explored the role of gender,…

On international comparisons, the development of Oman's education system in terms of the increase in educational enrolment rates and in the level of teacher qualifications has been remarkably rapid. Almost 100% access to basic education has been achieved, and almost all students progress onto post-basic education. A report from the World Bank in…

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…

TIMSS and PIRLS assess representative samples of students at regular intervals, measuring trends in student achievement and student contexts for learning. Because individual students are not tracked over time, analysis of international large-scale assessment data is usually conducted cross-sectionally. Gustafsson (2007) proposed examining the data…

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…

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…
