What age will you learn about puberty at school?

The age at which children learn about puberty in school varies depending on the country, state/province, and even the specific school district. There's no single global or even national standard. However, it's generally introduced in the upper elementary grades (around grades 4-6, ages 9-12), though some schools might start earlier or later. The information provided often increases in detail and complexity as students get older, progressing through middle and high school.
