Although female students' overall performance in mathematics is on a par with the performance of male students, female students tend to report lower levels of mathematics self-concept (MSC) than their male schoolmates. With the present study, we examined for the first time whether occupational gender diversity (i.e., a balanced gender ratio) in…

This article examines the extent to which parental socioeconomic status (SES) affects the likelihood of a child becoming a top-performing student, offering an international perspective by reporting this relationship in 31 developed countries. The impact of 3 important educational system characteristics (differentiation in terms of early tracking,…

We investigate the impact of external differentiation and vocational orientation of (lower and upper) secondary education on country variation in the mean numeracy skills of, and skills gaps between, adults with low and intermediate formal qualifications. We use data on 30- to 44-year-olds in 18 countries from the 2011-12 round of the Program for…

The impact of socio-economic background on mathematics performance in England can be seen from the most to least disadvantaged. As socio-economic background of pupils increases, so does average mathematics performance; the gap between the most and least disadvantaged is equivalent to over three years' of schooling. However, many factors other than…

This paper investigates achievement gaps between low and high socioeconomic students in 19 high-income countries. On average, math scores of students with indicators of high socioeconomic status (SES) are over one standard deviation above those with low SES indicators. The paper estimates the extent to which these achievement gaps can be…

At the end of secondary education in The Netherlands, students have to pass a final examination, consisting of an internal school-based assessment and an external national assessment. According to the Dutch inspectorate, to ensure the quality of final examinations, the discrepancy between both assessments must be less than 0.5 points (on a scale…

This article examines equity in national systems of education in terms of differences in student outcomes, as measured by mathematics achievement scores on Programme for International Student Assessment (PISA) 2003. The author uses four measures for assessing equity in student outcomes: (1) the strength of the relationship between student…
