Single-sex high schools help to produce better students because there are fewer distractions in these kinds of schools than in co-educational schools. Nowadays, students are learning more than ever before, and while they are trying to understand all this new knowledge, they do not need distractions. If boys and girls are studying together, they may become more focused on each other and not concentrate on the lesson. For example, a male student might be more interested in impressing a female peer than listening to the teacher; similarly, female students might get into arguments over popular boys, or spend their time discussing the boys in their class instead of listening to the teacher. If high schools are single sex, these kinds of distractions can be reduced.
单一性别高中有助于培养出更好的学生，因为这些学校的干扰比在共同教育学校少。如今，学生在学习的时候比以往任何时候都要多，而他们也在尝试着去理解所有这些新知识，他们不需要分心。如果男孩和女孩一起学习，他们可能会变得更加专注于对方，而不是集中精力在课程上。例如，一个男学生可能更感兴趣的是，在令人印象深刻的女性同伴比听老师；同样，女学生可能进入争论受欢迎的男孩，或花时间讨论的男孩在他们的阶级，而不是听老师。如果高中是单一性别，这些类型的干扰可以减少。
