The results presented here are taken from empirical studies relating to the relation between academic achievement and sex, type of school, and self-esteem, as well as self-esteem and sex, school level, and academic achievement. Aside from specific issues, these results show, first, that levels of achievement and self-esteem in middle school show much lower values than in high school and primary school. Secondly, although girls show a higher level of achievement, there is no difference between their self-esteem compared to the self-esteem of boys.
