I found it an interesting discussion so thought it would be worth having a new thread as the old is now full.
Just before the thread reached its post limit I posted a large government funded study which found that girls in single-sex schools are 'significantly more likely' to suffer threats of violence and actual violence than girls at mixed schools.
Unfortunately, it was too late in the thread to receive any replies but I thought it was an interesting statistic as many posters were suggesting that the benefit of single sex schools was a safer environment away from the boisterous/aggressive nature of boys.
