The National Federation of State High School Associations'
(NFHS) free online concussion safety course "Concussion in Sports -
What You Need to Know" has been taken by over 1 million people since it was introduced in 2010.
The National Federation of State High School Associations (NFHS) is implementing a new concussion rule for the 2010-11 academic year which not only requires immediate removal of any athlete suspected of having suffered a concussion but bans his return until cleared to play by an appropriate health-care professional. This rule also covers youth leagues that play under high school rules or modified high school rules, but does not apply in those states where even stricter concussion laws have been recently passed.
