I needed a background check for a teaching job, because a few (2 - 3 %) of the students were 17. The rest were over 18.
And we had to attend Mandatory Notification Training. Here, if you have grounds to suspect a child is being abused, you MUST report it. They told us what to look for, how to handle it, and who to tell.
It was a bit silly for us, because it was couched in terms of primary school kids whicih we never see. But, it is part of an overall package against child abuse and I'll put up with a paid day in training as part of that.
