Schools are under a duty to supervise adequately the students in their charge, and they will be held liable for foreseeable injuries proximately related to the absence of adequate supervision. The duty of care is that of a reasonably prudent parent. Where an accident occurs in so short a span of time that even the most intense supervision could not have prevented it, lack of supervision is not a proximate cause of the injury, and summary judgment in favor of a defendant charged with the duty of reasonable supervision is warranted.
