Background: In response to the rising incidence of concussions among childrenand adolescents, the province of Ontario recently introduced the OntarioPolicy/Program Memorandum on Concussions (PPM No. 158) requiring schoolboards to develop a concussion protocol. As this is the first policy of itskind in Canada, the impact of the PPM is not yet known. Methods: An electronic survey was sent to all high school principals in theToronto District School Board 1 year after announcement of the PPM.Questions covered extent of student, parent, and staff concussion educationalong with concussion management protocols. Results: Of 109 high school principals contacted, 39 responded (36%). Almostall schools provided concussion education to students (92%), with mosteducation delivered through physical education classes. Nearly all schoolshad return to play (92%) and return to learn (77%) protocols. Although 85%of schools educated staff on concussions, training was aimed at individualsinvolved in sports/physical education. Only 43.6% of schools deliveredconcussion education to parents, and many principals requested additionalresources in this area. Conclusions: One year after announcement of the PPM, high schools in the TorontoDistrict School Board implemented significant student concussion educationprograms and management protocols. Staff training and parent educationrequired further development. A series of recommendations are provided toaid in future concussion policy development.
