Read the passage carefully.
Middle schools and high schools should be either all boys or all girls because students in single-gender schools perform better academically. A 1993 study found that in mixed-gender schools, teachers favored boys over girls by allowing boys to call out but reminding girls to raise their hands when they did the same.
According to the National Coalition of Girls’ Schools, “Girls who attend single-sex schools outscore their coed counterparts on the SAT by an average of 28-43 points.” Studies show that boys also benefit from single-gender classrooms because they are more apt to engage in varied activities and try new things without fear of embarrassment. Likewise, girls are more likely to excel in traditionally male-dominated STEM courses when they are in an all girls’ environment.

The study from 1993 is outdated.
Separating by gender seems unfair.
