Certified athletic trainers have, at minimum, a bachelor's degree, usually in athletic training, health, physical education or exercise science. In addition, athletic trainers study human anatomy, human psychology/counseling. Certified athletic trainers also participate in extensive clinical affiliations with athletic teams under appropriate supervision.

Certified athletic trainers have fulfilled the requirements for certification established by the National Athletic Trainers' Association Board of Certification, Inc. (NATABOC). The certification examination administered by the NATABOC is now a computerized exam that assesses a candidates ability to successfully demonstrate the 6 domains of athletic training. It includes athletic training related situations designed to approximate real-life decision making. 

Domains of athletic training:

• Prevention

• Clinical evaluation and diagnosis

• Immediate care

• Treatment, rehabilitation and reconditioning

• Organization and administration

• Professional responsibility

Once athletic trainers pass the certification examination proving skills and knowledge within each of the five domains, they use the designation "ATC."
