Scotland’s score for Science has remained higher than the OECD average but has declined since 2012. Germany’s average score was consistently the highest of all of the selected OECD countries.


The Programme for International Student Assessment (PISA) is an assessment of 15 year-olds’ skills carried out under the auspices of the Organisation for Economic Co-operation and Development (OECD). The programme runs every three years across all OECD members and a variety of partner countries. Scotland has participated since the first wave of testing in 2000.

Around 510,000 students participated in the study worldwide. This includes the 34 member states of the OECD and 31 “partner countries and economies”.
