This guide is designed to help parents determine what is being taught to their children about sex education in school, offering tips on how to talk to children about these issues. The first section presents pointers from the "Talking with Kids" campaign: start early; initiate conversations; talk about sex and relationships; create an open environment; communicate one's values; listen to one's child; try to be honest; be patient; use everyday opportunities to talk; and talk about it repeatedly. The next section discusses how to get the conversation going, offering such possible conversation starters as "Have you noticed any changes in your body?" and "Do your friends ever talk about kissing or about their boyfriends and girlfriends?" The third section discusses sex education and age-appropriate topics, presenting pointers from child development experts on talking with children about sex at the right time in their lives. The fourth section explains how to find out about school sex education classes (e.g., call or visit the school, examine the child's health class textbook, and use the local and national PTA as a resource). A list of resources includes resources for parents and youth, resources on specific topics, and books. (SM)
