Comprehensive sex education; require teaching of in Grades K-12.

Mississippi's HB 350 requires all K-12 public schools to teach comprehensive sex education, emphasizing abstinence as the expected norm while mandating medically accurate information. The curriculum must cover HIV/STI prevention, contraception effectiveness, consequences of unintended pregnancy, sexual assault prevention, and healthy relationship skills - all presented as age-appropriate. Parents may opt their child out of the course with written notice, and the bill specifies that instruction must include factual statistics on contraceptive success/failure rates and legal consequences of sexual activity. The law amends state education codes to require school boards to implement this program and ensures nurses provide related health education.
