According to SIECUS, the Sexuality Information and Education Council of the United States, 93% of adults they surveyed support sexuality education in high school and 84% support it in junior high school. In fact, 88% of the parents of junior high school students and 80% of parents of secondary school students believe that sex education in school makes it easier for them to talk to their adolescents about sex. Also, 92% of adolescents report that they want both to talk to their parents about sex and to have comprehensive in-school sex education. Furthermore, a "study, conducted by Mathematica Policy Research on behalf of the U.S. Department of Health and Human Services, found that abstinence-only-until-marriage programs are ineffective."
