性教育
Traditionally, schools have begun teaching sex education in fifth and sixth grade, focusing primarily on puberty and reproductive anatomy and physiology. Sex education in these grades is often referred to as puberty education in order to reflect the emphasis on preparing children for the changes that all humans experience as they develop into adults. Little data is available for how much sex education is taught in elementary, but increasing numbers of schools are beginning developmentally appropriate sex education beginning in kindergarten in alignment with the National Sexuality Education Standards (NSES).
