Existing evidence shows that female students are less likely than males to study disciplines with higher labour market returns (e.g. STEM subjects), as discussed above (OECD, 2014b, 2015a). Special efforts should be made to get girls more interested in mathematics and science and boys more interested in reading. Gender bias in curricula should be removed (e.g. by phasing out gender stereotypes from textbooks, promoting female role models, and using learning materials that appeal to girls). Awareness should be raised on the likely consequences of choosing different fields of study for careers and earnings (OECD, 2012).
