health education; fetal development instruction

HB 2670 requires Arizona public schools to include specific fetal development instruction in health education for students in grades 7 and 8, covering human reproduction, pregnancy, infertility, and trimester-by-trimester growth of an unborn child. School districts may also offer age-appropriate fetal development lessons in grades 1-6 or 9-12. Parents can opt their child out of this instruction, and schools must notify parents about the curriculum and withdrawal options. The bill passed the legislature in April 2025 but was vetoed by the governor on April 18, 2025, so it did not become law.
