Many states are shifting their approach to sex education in K-12 schools with stricter regulations on when and what students learn about their bodies. It's a move that has further complicated and polarized sex education. A dozen state or county agencies recently parted ways with federal grants that help monitor teenagers’ sexual behaviors and lower rates of STDs. Several states have pushed back the grade level at which sex education begins. Experts say they are concerned students won’t reliably learn about adolescence, safe sexual activity or relationship violence.
