If you use Barker as the example, then you'd have to think they're not going to enjoy the outcome. Fewer boys means less depth. Less depth means fielding competitive A grade teams becomes more difficult (and prone to fluctuations based upon injury). And of course fewer teams has a flow on effect to the rest of the competition when larger schools have to scramble each week to find someone to play. Joeys 8th playing Riverview 6th every second week
This sudden rush to create co-ed schools from Independant boys schools is short sighted and wreaks of trendy-ness. It seems everyone has forgotten that boys and girls learn differently and you've now made it significantly harder for your classroom teachers to now have to cater for this. It also seems to ignore that there is a mountain of evidence that supports the efficacy of single sex schools.
Whilst I agree that having a socially well adjusted child is a good thing, I dont think I'm willing to pay $40k plus for the privilege AND at the expense of their education and co-curricular ambitions.
Also interesting to note that there isn't any independent girls schools rushing to open the doors to boys. I wonder why that is?
