The clinic is open during school hours. A school nurse is assigned to Key School/Escuela Key two days a week and a nurse’s assistant is on duty daily. The clinic phone number is (703) 228-8484. Check with the clinic on the school’s Medication Policy. Several days in the fall are set up as Health Screening Days. The nurse’s assistant and PTA volunteers do vision screening for all first, third and fifth graders. Parents are notified if their child’s results warrant a professional vision evaluation.
