With the aim of developing an assessment more appropriate for low-income countries, in 2013 the Organisation for Economic Co-operation and Development initiated the Programme for International Student Assessment for Development (PISA-D). Designed as a one-off assessment project resulting in scores comparable to PISA, nine countries joined the…

Gender gaps in school enrollment and achievement are usually investigated as separate facets of gender inequality in education. This study suggests that they might be linked by design. If boys and girls differ in their school enrollment rates, the student population will be gender biased. Since out-of-school adolescents tend to be less advantaged…

In low-income countries, there exists a common concern about the effect of hunger and food insecurity on educational outcomes. However, income inequalities, economic slowdown, conflict, and climate change have raised those concerns globally. Yet, little is known about how widespread the problem of hunger in schools is worldwide. This study…

Test items must often be broad in scope to be ecologically valid. It is therefore almost inevitable that secondary dimensions are introduced into a test during test development. A cognitive test may require one or more abilities besides the primary ability to correctly respond to an item, in which case a unidimensional test score overestimates the…

Although the root-mean squared deviation (RMSD) is a popular statistical measure for evaluating country-specific item-level misfit (i.e., differential item functioning [DIF]) in international large-scale assessment, this paper shows that its sensitivity to detect misfit may depend strongly on the proficiency distribution of the considered…

Modern international studies of educational achievement have grown in terms of participating educational systems. Accompanying this development is an increase in heterogeneity, as more and different kinds of educational systems take part. This growth has been particularly pronounced among low-performing, less economically developed systems.…

In spite of the challenges inherent in making dozens of comparisons across heterogeneous populations, a relatively recent interest in scale-score equivalence for non-achievement measures in an international context has emerged. Until recently, operational procedures for establishing measurement invariance using multiple-groups analyses were…

International large-scale assessments such as the Programme for International Student Assessment (PISA) have emerged as important tools for understanding educational systems within Asia and around the world. Although the achievement scales tend to capture the majority of the world's attention the background scales have become important tools in…

Participation in international large-scale assessments has grown over time with the largest, the Programme for International Student Assessment (PISA), including more than 70 education systems that are economically and educationally diverse. To help accommodate for large achievement differences among participants, in 2009 PISA offered…

Given the importance of large-scale assessments to educational policy conversations, it is critical that subpopulation achievement is estimated reliably and with sufficient precision. Despite this importance, biased subpopulation estimates have been found to occur when variables in the conditioning model side of a latent regression model contain…

In the current article, we consider the influential position of the Programme for International Student Assessment (PISA) and discuss several methodological areas that demonstrate the need for caution when using and interpreting PISA results. We motivate our argument by briefly describing the program's increased influence in educational policy…

Over time international large-scale assessments have grown in terms of number of studies, cycles, and participating countries, many of which are a heterogeneous mix of economies, languages, cultures, and geography. This heterogeneity has meaningful consequences for comparably measuring both achievement and non-achievement constructs, such as…

Background: When studying student performance across different countries or cultures, an important aspect for comparisons is that of score comparability. In other words, it is imperative that the latent variable (i.e., construct of interest) is understood and measured equivalently across all participating groups or countries, if our inferences…
