This paper examines the effect of COVID-19 on learning loss and learning inequality in South Africa using 2016 and 2021 Grade 4 PIRLS datasets. On average, South African Grade 4 reading achievement declined by 31 PIRLS points from 320 in 2016 to 288 in 2021, equivalent to a decline of 0.29 standard deviations or 50-60% of a year of learning. The…

The effect of composition may be strong in systems where students are systematically sorted based on their socio-economic background. This paper aims to model the differential effect of class composition on pupils' achievement in Belgium (French-speaking Community), France, Spain and Portugal. Multilevel models are consequently tested on the…

Few developing countries participate in external educational evaluations. Information gaps on education quality make it imperative to expand such evaluations. Furthermore, international comparability across different evaluations should be improved. In addition, data from evaluations must be combined with data on access or coverage. Finally,…

In a recent paper, Reardon found that the relationship between family income and children's academic achievement grew substantially stronger in the 1980s and 1990s in the United States. We provide an international context for these results by examining the income-achievement association in 19 other Organisation for Economic Co-operation and…

This paper examines changes in demographic and socioeconomic inequalities in student achievement over the school career, and the extent that these inequalities are accounted for by other influences such as, region and socioeconomic background (where appropriate), school differences and prior achievement. The data analysed are from a longitudinal…
