Under AB 329, abstinence may not be discussed in isolation from other methods of preventing HIV, other sexually transmitted infections — or STIs — and pregnancy. However, the law requires that instruction and materials include information explaining that abstinence is the only certain way to prevent HIV, other STIs and unintended pregnancies. It also states that “Instruction shall provide information about the value of delaying sexual activity while also providing medically accurate information on other methods of preventing HIV and other sexually transmitted infections and pregnancy.”
