Requiring parental or legal guardian approval before a child participates in comprehensive sexual health education.

SB 5137 requires Washington public schools to obtain written approval from a child's parent or legal guardian before providing comprehensive sexual health education. This replaces the current system where parents could opt their child out with a written request, making parental consent mandatory prior to any instruction. The bill maintains existing curriculum requirements (including medically accurate, age-appropriate content covering abstinence, contraception, and affirmative consent) but shifts the process to require active parental approval. It directly affects parents/guardians of K-12 students in Washington public schools and takes effect starting the 2025-26 school year. The law amends RCW 28A.300.475 to formalize this approval requirement.
