R.I. Gen. Laws § 16-21-10: Scoliosis screening.

The school health program shall provide for the yearly screening or examination for scoliosis of all school children in grades six (6) through eight (8) and the preservation of records of the screening or examinations of those children. The parent or guardian of any child in grades six (6) through eight (8) may have the screening or examination conducted by a private physician and the results shall be made available to the local school department. Otherwise, the screening shall be conducted by a certified nurse-teacher. The screening of male and female pupils shall be conducted separately. The parent or guardian of any child who is found to have positive signs or symptoms of scoliosis shall be notified of the findings. However, the test shall not be required of any student whose parents or guardian objects on the ground that the test conflicts with their religious belief.
