The law requires the Illinois High School Association to develop an online concussion certification program.
Quinn says the idea is to reduce and prevent concussions among high school athletes. The Chicago Democrat signed the measure Tuesday at a school on Chicago's South Side. The law takes effect immediately.
Studies indicate concussions in children and teens have increased in recent years, along with awareness about the dangers of these head injuries.
The training will center on preventing and recognizing concussions, including what the long-term effects of repetitive head trauma are. Student athletes will also get awareness training.
