The Maryland state school board has adopted new regulations that beef up protocols for addressing head injuries and require more concussion training for those responsible for student-athletes. The Baltimore Sun says an advisory board will recommend limitations on contact exposure in sports where concussions occur. The regulations include training for physical education teachers and a biennial refresher for coaches. School districts will be required to draw up policies that address academic accommodations for injured students; they must document oral and written notification to parents and guardians when a concussion has been sustained, and provide timely notification to athletic directors and school nurses. The regulations also call for identifying health care providers authorized to permit students to return after a concussion.
