My DS8 goes to a prep school style school, 6th -12th grade. For the middle school years 6-9, the classes are gender separated. This was done based on studies that showed that this age group, particularly boys learn better when they aren't distracted by the opposite sex. They are all together during passing period, lunch etc.

The school is #1 in the state in math and science so I'm not complaining. My son could care less either way since he's still several years from puberty and generally thinks girls have cooties!
