What is Athletic Training?

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.

Athletic trainers 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.

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.

For more information on the education and skills of certified athletic trainers, please visit NATA At Your Own Risk.


The Athletic Training Room opens at 11:00 am on school days.

Student athletes are encouraged to take advantage of their free time (lunch, SRT, study hall) for injury evaluation, rehabilitation, and treatment. Athletic training services are provided until the conclusion of practices and games each day.

When an injury requires further evaluation by a physician, student athletes are required to obtain a written doctor’s note to return to the athletic trainers. The athletic trainers cannot proceed with injury clearance without this written documentation by the physician. It is always easier to get this note while still at the physician’s office; please make sure to ask for one before you leave your appointment.
