The reality is that some schools are being run by a bunch of lawbreakers. The correct response would be to punish them, not to allow them to illegally beat the children instead. Children are being excluded simply for having wrong haircut! We can also see a reason why more boys than girls are likely to be excluded –
“The inquiry found several schools “clearly discriminated” against some pupils with rules on hair length that only apply to boys and rules on hairstyles that are much more likely to be worn by particular ethnic groups.”
