It is a measure of the concern social media is causing schools that one Auckland school, Kowhai Intermediate, is trying to ban its use by pupils not just in school grounds but in their lives outside for the two years of their attendance.
Good luck with that, will be the common response to our report today.
It is not a rule the school, or even the children's parents, will be able to enforce easily.
But if pupils complain of online bullying by others in the school, or are disturbed in any way by what classmates do on social media, the culprits will have broken school rules and the principal can take action.
The school has made the rule so that when parents of victims ask it to do something, it can do something when the behaviour occurs outside school hours.
