TOPEKA, Kan. (AP) — The Kansas House is expected to debate a bill later this month that would require parents’ consent before students attend sex education class.

The so-called “opt-in” bill that was approved by the House Education Committee last month also would allow parents to review the curriculum before enrolling their children in classes. Most of the 286 school districts have “opt-out” policies in which students are enrolled in sex education courses unless parents sign a form to exempt them.

Critics say the bill tampers with the proven success of sexual education. Teen births in Kansas are down 50 percent since peaking in the early 1990s.

Education Committee Chairman Rep. Ron Highland, a Republican from Wamego, said the bill will likely pass when it comes to a floor vote.
