The article is focused on the gender gap in achievements at Czech primary and secondary schools. Educational outcomes include both grades and results in external didactic tests.
There is a substantial discrepancy between grades and tests, especially in mathematics – on average, girls achieve better grades but boys have better test results. This contradiction is explained by using the gender inequality concept.
The article presents and analyzes the dominant interpretations in this field and argues against the approach saying that boys are disadvantaged at schools.
