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 an age-appropriate human growth and development curriculum in health or science classes, directly affecting students in grades K-12, parents/guardians (via opt-out rights), and school districts (responsible for implementation). The curriculum must include specific content: human biology related to pregnancy, fetal development inside a womb, a 3-minute high-definition ultrasound video of fetal development, and computer-generated animations showing cell and organ growth. Parents may opt their child out of the curriculum two weeks before instruction using a state-prescribed form. Students in grades 9-12 must complete this instruction to graduate with a standard diploma unless an opt-out form was submitted. The law takes effect November 1, 2025.
