18VAC85-80-110  Supervisory responsibilities of an occupational therapist.  Section B states that supervision is to occur "at  least every tenth session or 30 calendar days".  Section D states that the supervising therapist must  "review and countersign within 10 days recordings" in the patient record.  If you have to countersign a note within 10 days then you have to provide supervision at that time.  This would be very difficult to acheive in a school setting.  Please consider documentation by the suprevising OTR every 30 days or 10th visit that supervision has occured.
