Do you think that adults or people in the school system have right to check students lockers without them knowing or approval?
I think they should not be allowed to do this unless they have some kind of serious reason to, ie. someone reported something in there.

I think having a frequent checking is needed because the school needs to control things. it'll be too late if there's a complaint about things the student bring to school or keep in the locker.
I'd disagree if they do it everyday, but maybe once a month is better.

What if there are private/embarrassing things in there that you do not want anyone to know about? I think the parents should check in the locker instead of the school.
