Single-Sex vs. Coed: The Evidence
What's the evidence? What have researchers found when they compare single-sex education with coeducation?
Let's begin with two recent studies in which students were RANDOMLY assigned either to single-gender or coed classrooms, with no opt-out. We are aware of no other studies in which students were randomly assigned either to single-gender or coed classrooms, with no parental opt-out allowed. Any such study would be illegal in the United States; in the United States, federal statute 34 CFR 106.34 requires that any assignment to a single-gender classroom or school must be completely voluntary.
