Board members on Wednesday considered objections to explicit material that had been recommended for use and removed some of it. Concerns were expressed that some of the material was too explicit or seemed to be endorsing specific sexual activity. Among the targets: a book titled “S.E.X.: The All-You-Need-to-Know Sexuality Guide to Get You Through Your Teens and Twenties."
In the end, the panel voted to approve a broad framework for comprehensive sex education that it says is age-appropriate and important for young people to know to stay healthy.
