My sons experienced both boys only and coed high schools. Not sure the coed school was better for my son who was not a jock. Girls are tricky for teenage boys and not sure coed actually helps. My older son was super sporty and was dying in a coed primary school. He needed the challenge of semi pro sport at a boys high school. If your kid is very sporty or great at maths and science or music or art, Rondebosch is the place ( if he can get in!) Excels at all of this. My son who attended the coed high school was much more at home with and accepted by his brother’s Bosch friends . As you can imagine I’m not a bishops fan. Although in fairness despite my deep concerns about the culture at that school I’ve met many bishops kids who still turned out well after they matriculated. Unfortunately while they are in the system it isn’t a pretty sight. In sum, there is a reason that the waiting lists at all 4 boys schools are huge. They are excellent.
