charliehall — With regard to your last point, in NYS educators are also mandated reporters. If I recall correctly there is a bit of wiggle room in that a school could set up a structure where one individual is the mandated reporter (i.e. a principal), and everyone else only has an obligation to report suspicion of abuse to him. But most yeshivos do not have that set up anyway, so anyone going into Chinuch should clarify this issue with their posek and a lawyer.
BTW, just for interest sake, in Israel EVERYONE is a “mandated reporter”, meaning if it comes out that you had information about suspected abuse and don’t report it to the authorities you could be held legally liable. Obviously this is very hard to prosecute practically, but technically that is the law.
