Schools; requiring age-appropriate human growth and development curriculum to be taught in public schools; guidelines and resources; effective date.
HB 1603 requires Oklahoma public schools to teach a specific human growth and development curriculum, including a high-definition ultrasound video showing fetal development and a computer animation of cell/organ growth. It mandates this content be delivered in an age-appropriate manner, with parents able to opt their child out using a state-prescribed form two weeks before instruction. The bill affects all public school students in grades 9-12, as completion of this curriculum is required for graduation with a standard diploma unless a parent opts out. Schools must integrate this into health or science courses and align it with state academic standards, effective November 1, 2025.
