California Gov. Jerry Brown has signed legislation aimed at making the state the first in the nation to bring lessons about sexual consent into high schools.
Last year, California became the first state to require colleges and universities to apply a "yes means yes" standard when investigating campus sexual assault claims. The policy requires conscious, voluntary agreement between partners to have sex.
The bill Brown endorsed requires school districts that include health as a graduation requirement to teach "yes means yes" and sexual violence prevention starting next year.
It also asks state education officials to update curriculum guidelines for high school health classes with information about those topics.
Supporters say the law will reduce sexual assaults among teenagers and young adults. It had no organized opposition.
