Legal Question in Education Law in Illinois

This is really copyright law. Your daughter owns the "copyright" of the IMAGE, meaning she (and since she is a minor? you as the parent/guardian) has protected interests, in the image. So technically the school needs her/your permission to copy it. But simply to hang it (with other student art???) the school can do so. As to who owns the paper or whatever it is drawn/painted on, is a different story.
