The gender gaps in mathematics and reading achievement refer to the finding that, on average, boys and girls perform differently in mathematics and reading skills on tests.
[1][2][3] The Programme for International Student Assessment assesses the performance of 15-year-olds in mathematics and reading in OECD and OECD partner countries.
[4] The table below lists the scores of the PISA 2009 assessment in mathematics and reading by country, as well as the difference between girls and boys.
A positive mathematics gap means that boys outperform girls, while a negative mathematics gap means that girls outperform boys.
A positive reading gap means that girls outperform boys (this is true in every country, so no country has a negative reading gap).
