Education: curriculum; health education standards and guidelines; modify to include instruction on human development. Amends 1976 PA 451 (MCL 380.1 - 380.1852) by adding sec. 1170c.

HB 4286 requires Michigan public schools to update health education curriculum standards by the 2026-2027 school year. It mandates specific content about human development, including an overview of pregnancy biology, fetal development inside the uterus, a 3-minute high-definition ultrasound video of early fetal organ development, and a computer-generated animation showing fertilization through birth. The bill directly affects Michigan public schools and the state Department of Education, which must revise curriculum standards to include these requirements. This is a concrete policy change to the health education curriculum, not a procedural or commemorative measure.
