To allow public schools that offer sexual health education to assure that it is medically and scientifically accurate, age appropriate, appropriate for students regardless of gender, race, disability statute, or sexual orientation, and include information about abstinence and other methods of preventing unintended pregnancy and sexually transmitted disease. Abstinence education may be taught to the exclusion of other materials and instruction. Sexual health education should be as consistent as practicable with the guidelines for sexual health information and disease prevention.
