<p>Interaction with the opposite sex could make a difference with some kids who go to single sex schools. There is always that group of kids where some factor that does not matter much to the main stream would matter to them. It is entirely possible that a shy child who has little interaction with the opposite sex and ends up at a single sex school could end up avoiding contact nearly altogether and be very uncomfortable with the opposite sex. Harder to happen at a coed school. That was in part why I wanted a coed environment for my kids. My husband’s genes make for pretty much an all male family in terms of our kids and cousins. I have only brothers. Which pretty much leaves me the only shining example of feminism in their lives. The burden is just too much for me. LOL. But, the two with the most coed education and exposures are the two with least understanding of females. My kids at the all boys schools have female friends from neighboring kids, sisters of friends, activities, old nursery school friends and just meeting girls from where ever. Though my one son has been at a coed highschool, the group of guys he’s with don’t seem to hang around the girls yet. Very young group of boys, in my opinion which seems to be a large part of the equation. But perhaps they would be even more withdrawn and perplexed by females if they were at an all boys’ school? Possible. </p>
<p>I know that when certain all boy schools went coed in my lifetime, the all girls schools nearby did suffer in the marriage rate with males from a particular school. When I was a kid, many. many doctors were married to nurses. I know now, many doctors are married to fellow doctors which has to drop into the nurse/doctor marriage rate. </p>
<p>That’s why I would not want to blanketly say that single sex environement are better for all. It really does depend on the circumstances and the people involved.</p>
