With there being more opportunities for girls, there is more expected of them. Teachers also now have a different expectation of girls.
Schools have become more female dominated environment which benefits girls but can make boys feel less comfortable, sociologists call this a 'feminisation of education'.
There are more female teachers in schools, especially primary schools, which gives girls a role model that boys then lack.
In 2015 the Department for Education's school workforce showed that the number of male teachers working in Britain had fallen for the 5th consecutive year. In 2012, 1 in 4 teachers were mean, and in 2015 it had fallen to 1 in 5.
Teachers often respond to the stereotypes of boys being lively and girls being academic.
