Many are concerned about the large decline in K-12 student achievement since 2019. And rightly so, given what it signals about student learning and later life outcomes. Less noted is the pre-pandemic sustained decline in student achievement growth that followed 30 years of increases. We examine the nature of achievement decline as measured by…

Standardised International Large-Scale Assessments (ILSAs) have gained prominence in global and national educational discussions. ILSAs claim to offer valuable insights for improving education systems, but their impact on educational policy varies and has become a contested arena. This article analyses how these assessments fed educational…

Previous studies have shown that educational expectations of individuals with high socioeconomic status (SES) are relatively unaffected by low academic performance, a phenomenon called "sticky expectations." However, this result might be biased by endogeneity and reverse causality between academic achievement and educational…

Influencing major education policies in the US such as school vouchers and charter schools, market theory assumes that organizational autonomy, parental choice, and competition between schools improve the quality of education. However, whether those policies can influence the instructional core of schools is not well understood. Comparing private…

International Large-Scale Assessments (ILSAs) have had significant impact on education policy across the globe. But has interest in ILSAs now started to wane? This paper presents new evidence on this issue, exploring how the amount of attention three major ILSAs receive compares across countries, between studies and over time. Using information on…

Using data from the Trends in International Mathematics and Science Study (TIMSS), this study examines the student and school characteristics that contribute to students' mathematics performance in early elementary school in Chile. Previous research has separately analyzed the association of student and school factors with mathematics performance.…

In 2021, an OECD team undertook analysis of Republic of Türkiye's data from two international assessments--the OECD Programme for International Student Assessment (PISA) and the International Association for the Evaluation of Educational Achievement (IEA)'s Trends in International Mathematics and Science Study (TIMSS). The analysis aimed to…

The quality of education is a predictor of a country's economic performance -- which is why comparative international education surveys are important. South Africa performed poorly in the Trends in International Mathematics and Science Study (TIMSS) in 2019. The score of 374 for mathematics and 324 for science is poor compared to the mid-point of…

This brief examines Trends in International Mathematics and Science Study (TIMSS) science achievement of the 20% highest and the 20% lowest performing fourth and eighth graders in 11 countries. To do so, the authors compare achievement distributions across countries, using measures of relative equality within countries. Such an examination…

Students living in poverty tend to perform worse in school than their peers from better-off families. This paper examines whether computer availability helps narrow down educational inequalities in Slovakia, using TIMSS and PIRLS data. The results show that computer availability in reading lessons improves reading scores and that the effect is…

Although International Association for the Evaluation of Educational Achievement-pioneered international large-scale assessment (ILSA) of education is now a well-established science, non-practitioners and many users often substantially misunderstand how large-scale assessments are conducted, what questions and challenges they are designed to…

Understanding the long-standing educational inequities associated with socioeconomic status remains significant for transforming educational policies and practices. To better understand entanglements among socioeconomic status and students' performance in mathematics, we examined different home factors (including language of the test) that…

Kuwait, has participated in international TIMSS test for many years, however, there has been little systematic effort to compile and assess changes between genders. This study attempts to look at the results of Kuwaiti students on the TIMSS mathematics assessments in general and according to gender in particular and the views of supervisors on the…

This study used mixed methods to investigate the relationships between parental leave policy components and academic achievement measured by TIMSS and PIRLS. Qualitative document analysis was used to analyze the policy documents and available literature on all the parental leave policies that had been implemented early enough to potentially affect…

The discourse of quality has permeated everyday discussions about education, yet the concept as such remains complex. Moreover, during the constant struggle to improve educational quality, governments have increasingly devoted attention to the results of international large-scale assessments. As those results are used to inform policy decisions to…
