The data showed that the gender gap in grades favors girls from an early age. The authors hypothesize that the higher grades for girls result from non-cognitive skills such as “how well each child was engaged in the classroom, how often the child externalized or internalized problems, how often the child lost control and how well the child developed interpersonal skills.” In other words, girls’ attitudes and behavior in the classroom have an impact on their grades.
The vast majority of elementary school teachers are women but the authors state there is not sufficient data to determine if the gender of the teacher has any impact on the gender gap in grades.
