Trained Public Health Nurses perform screenings for vision and scoliosis at all Putnam County Schools. Vision testing is completed in grades Kindergarten, 1, 3, 5, 7, and 9. Scoliosis screening is done in grades 6, 7, and 8. Screening does not replace an examination by a doctor. When the screening is not passed, a referral letter is sent home to parents recommending their child be seen by a physician or health care professional.
