Athletic training encompasses the prevention, examination, diagnosis, treatment and rehabilitation of emergent, acute or chronic injuries and medical conditions. Athletic training is recognized by the American Medical Association (AMA), Health Resources Services Administration (HRSA) and the Department of Health and Human Services (HHS) as an allied health care profession.


Who are athletic trainers?

Athletic trainers (ATs) are highly qualified, multi-skilled health care professionals who collaborate with physicians to provide preventative services, emergency care, clinical diagnosis, therapeutic intervention and rehabilitation of injuries and medical conditions. Athletic trainers work under the direction of a physician as prescribed by state licensure statutes.

Athletic trainers are sometimes confused with personal trainers. There is, however, a large difference in the education, skillset, job duties and patients of an athletic trainer and a personal trainer. The athletic training academic curriculum and clinical training follows the medical model. Athletic trainers must graduate from an accredited baccalaureate or master’s program, and 70% of ATs have a master’s degree. Learn more about the education of athletic trainers.

The Guide to Athletic Training Services (pdf) describes the qualifications of athletic trainers and the clinical tasks they routinely perform in the delivery of quality health care.

A concussion is a brain injury and all brain injuries are serious.  They are caused by a bump, blow, or jolt to the head, or by a blow to another part of the body with the force transmitted to the head. They can range from mild to severe and can disrupt the way the brain normally works.


Even though most concussions are mild, all concussions are potentially serious and may result in complications including prolonged brain damage and death if not recognized and managed properly.


In other words, even a “ding” or a bump on the head can be serious.  You can’t see a concussion and most sports concussions occur without loss of consciousness. Signs and symptoms of concussion may show up right after the injury or can take hours or days to fully appear.  If your child reports any symptoms of concussion, or if you notice the symptoms or signs of concussion yourself, seek medical attention right away.


Management Protocol

In the event an athlete suffers a concussion, the following steps will be taken to ensure the highest level of care possible:


  1. The athlete will be removed from the game/practice for the remainder of the day (in accordance with CIF Bylaw 503.H and Ed. Code 49475).
  2. The certified athletic trainer will complete an initial evaluation, including administration of the Sideline ImPact test.
    1. If the certified athletic trainer is not present (i.e. away game, off-season practice, etc.) the coach will communicate the injury to the certified athletic trainer via phone call or text message, and the Sideline ImPact test will be given at the time of evaluation. 
  3. The parent/guardian will be notified via phone call, and the athlete will be sent home with the Concussion Clearance Packet.
    1. Athletes will be instructed to visit a physician as soon as possible (team physician preferred; must be MD or DO only*).
    2. Following the injury, the athlete and parent/guardian will complete the Post-Concussion Symptom Inventory on a daily basis until the athlete returns to be reevaluated by the certified athletic trainer.
    3. This will continue under the supervision of the certified athletic trainer until the athlete is released to full participation.
  4. The grade level coordinator (GLC), health office & school nurse will be notified via email, and a letter will be sent to the athlete’s teachers.
  5. At this time, the athlete will not be allowed to practice, condition, weightlift, or compete in any amount until written clearance is obtained by the evaluating licensed healthcare provider (MD or DO only) and the athlete completes the gradual Return to Play Protocol.


Clearance to Participate

In accordance with Ed. Code 49475 and CIF Bylaw 503.H: “A student-athlete who has been removed from play may not return to play until the athlete is evaluated by a licensed health care provider trained in education and management of concussion and receives written clearance to return to play from that health care provider.” (MD or DO only)
