There aren't any. It's a school for mentally or physically handicapped kids.
Actually, the student attended a school for handicapped or mentally ill children, but the afterschool program appears to have been open to all.
That does suggest a pretty good question, actually. I'm not sure about Florida, but where I am, even emotionally disturbed students are served in the regular school environment unless their disability is so severe that they pose a danger to themselves or others.
Perhaps the little girl shouldn't have been in that program to begin with.
