Athletic Trainers (ATs) are highly qualified, multi-skilled health care professionals who render service or treatment, under the direction of or in collaboration with a physician, in accordance with their education, training and the state's statutes, rules and regulations.  As a part of the healthcare team, services provided by Athletic Trainers include primary care, injury and illness prevention, wellness promotion and education, emergent care, examination and clinical diagnosis, therapeutic intervention and rehabilitation of injuries and medical conditions.  The NATA Code of Ethics states the principles of ethical behavior that should be followed in the practice of athletic training.

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.

Athletic Injury Protocol
Athletes should report ALL athletic injuries immediately to the CHHS Athletic Trainers. Athletes will be evaluated, and either referred to the CHHS Athletic Training Room for treatment and/or rehab or referred to a physician. Injuries will be documented in RankOne, and parents and coaches will be notified. The CHHS Athletic Trainers will provide appropriate paperwork needed for doctor's visits, which may or may not include an insurance claim form.

It is strongly recommended that athletes consult with the CHHS Athletic Trainers before seeking medical attention from a physician regarding non-emergent injuries.

When athletes are seen by physicians, they must provide the CHHS Athletic Trainers with a physician's note. Please make sure that all notes from physicians include the following:

  • Date of visit
  • Physician's name
  • Office phone number
  • Diagnosis
  • Treatment plan
  • Follow up instructions

We MUST have ALL physician's notes on file as it is required by GCISD. We MUST follow doctor's orders as they are documented. Student athletes will NOT be allowed to return to play without a note from the tending physician releasing them.

Treatment and Rehab Protocol
We provide acute and long term rehabilitation for athletic injuries. We work closely with our team physicians, and other medical professionals to provide quality healthcare to our athletes. 
Athletes are expected to attend their scheduled treatment and rehab times.
