OMAHA, Neb. (AP) — The Omaha Board of Education has approved an update to sex education standards after months of debate.

The board voted unanimously Wednesday to approve the new standards in elementary and middle schools. For the high school standards, one board member opposed.

The approval marks the first time this curriculum has been updated in nearly 30 years.

The new standards include discussion of sexual orientation and gender roles, as well as abortion and emergency contraception. It also includes lessons on social media, bullying and harassment.

The new model still stresses that abstinence is best for preventing pregnancy and sexually-transmitted diseases.

With a full board room Wednesday, the board voted to limit testimony to one hour. Ten of the 13 people who testified opposed the changes.
