S.C. Code § 59-32-50
Pursuant to policies and guidelines adopted by the local school board, public school principals shall develop a method of notifying parents of students in the relevant grades of the content of the instructional materials concerning reproductive health, family life, pregnancy prevention, and of their option to exempt their child from this instruction, and sexually transmitted diseases if instruction in the diseases is presented as a separate component. Notice must be provided sufficiently in advance of a student's enrollment in courses using these instructional materials to allow parents and legal guardians the opportunity to preview the materials and exempt their children.
A public school principal, upon receipt of a statement signed by a student's parent or legal guardian stating that participation by the student in the health education program conflicts with the family's beliefs, shall exempt that student from any portion or all of the units on reproductive health, family life, and pregnancy prevention where any conflicts occur. No student must be penalized as a result of an exemption. School districts shall use procedures to ensure that students exempted from the program by their parents or guardians are not embarrassed by the exemption.
