What enhances mathematical ability? A cross-country analysis based on test scores of 15-year-olds

This article examines the mathematical abilities of 15-year-olds in a range of countries which participated in the 2003 cycle of the Organization for Economic Cooperation and Development (OCED)'s Programme for International Student Assessment (PISA). Utilizing information on the scores obtained by individual students in the mathematical part of the PISA assessment, we use a range of indicators from the literature on inequality and poverty to evaluate the 'mathematical performance' of participating countries. Since data from PISA contained a wealth of information on the circumstances of the students in terms of their home and school environment, we identify and examine the relative influence of factors which serve to enhance the mathematical performance of students in the PISA assessment.
