well i would approach this situation carefully. it may be a form of discrimination. they may be exploiting those children. but then you might wonder if they are performing a civil service, for their school, whether it was voluntary or not. this may be a way to give those children the same oppurtunities as the other children. I don't know. I suggest you ask teachers first. because if you ask the administration first, and they are exploiting those children, they will know that you are on to them, and halt their activities. You need to catch them in the act, if that is the case.
