Students may enroll in required courses in the professional phase a maximum of two (2) times regardless of the final grade, including W, WP or WF. Please refer to the WCHP Graduate Program Progression Policies and Procedures (PDF) for a detailed description of academic standards.
Technical Standards
The Master of Science in Athletic Training (MSAT) Program at The SWAGƵ is a rigorous and intense program that places specific requirements and demands on the students enrolled in it. An objective of this program is to prepare graduates to enter a variety of employment settings and to render care to a wide spectrum of individuals engaged in physical activity. The technical standards set forth by the MSAT Program establish the essential qualities considered necessary for admitted students to achieve the knowledge, skills, and competencies of an entry-level athletic trainer; as well as meet the expectations of the program's accrediting agency CAATE. The following abilities and expectations must be met by all students in the professional program. In the event a student is unable to fulfill these technical standards, with or without reasonable accommodation, the student will be subject to dismissal. All MSAT students must be able to demonstrate competency for patient safety appropriate to the learner’s level of training. Demonstration of fluency of skills and knowledge appropriate to the level of training is a requirement for progression through the curriculum. Most assessments are designed to simulate activities in the clinical training and clinical practice settings and are tied to the learner’s demonstration of competency for patient safety. These assessments may be performed in a timed and structured environment and are designed to evaluate the learner’s ability to demonstrate appropriate fluency of skills and knowledge under specific conditions.
Compliance with the program's technical standards does not guarantee a student's eligibility for the BOC certification exam.
Candidates for selection to the MSAT Program must demonstrate:
- The mental capacity to assimilate, analyze, synthesize, integrate concepts and problem solve to formulate assessment and therapeutic judgments and to be able to distinguish deviations from the norm.
- Sufficient postural and neuromuscular control, sensory function, and coordination to perform appropriate physical examinations using accepted techniques; and accurately, safely and efficiently use equipment and materials during the assessment and treatment of patients.
- The ability to communicate effectively and sensitively with patients and colleagues, including individuals from different cultural and social backgrounds. This includes, but is not limited to, the ability to establish rapport with patients and communicate judgments and treatment information effectively. Students must be able to understand and speak the English language at a level consistent with competent professional practice.
- The ability to record the physical examination results and a treatment plan clearly and accurately.
- The capacity to maintain composure and continue to function well during periods of high stress.
- The perseverance, diligence and commitment to complete the athletic training program as outlined and sequenced.
- Flexibility and the ability to adjust to changing situations and uncertainty in clinical situations.
- Affective skills and appropriate demeanor and rapport that relate to professional education and quality patient care.
Candidates for selection to the professional (graduate) phase of the MSAT Program will be required to certify with the Program Director that they have read, understand and meet these technical standards or that they believe that, with certain accommodations, they can meet the standards. Please see the Student Access Center for more information.

Athletic Training Program FAQ
What is an athletic training degree?
An athletic training degree program combines the study of exercise science with the practices of preventing, managing, and rehabilitating injuries. Many students who are considering a degree in sports medicine, sports performance, kinesiology, or exercise science may actually be thinking of an athletic training degree.
Athletic training is a designated academic major or its graduate equivalent, recognized and accredited by the Commission on Accreditation of Athletic Training Education (CAATE). The minimum entry-level professional degree for athletic trainers is now a master's degree. Upon finishing a CAATE-accredited athletic training education program, students become eligible for national certification by successfully passing the Board of Certification, Inc. (BOC) examination.
SWAGƵ in Maine offers a CAATE-accredited Master of Science in Athletic Training (M.S.A.T.) degree program for those with a Bachelor of Science (B.S.) degree who meet all prerequisites. This is a two-year (24-month) program with classes and hands-on learning in our state-of-the-art facilities.

Is an athletic trainer the same thing as a personal trainer?
Athletic trainers are not the same thing as personal trainers. Athletic trainers are healthcare providers dedicated to the well-being of athletes, requiring master’s-level studies, along with required certifications. Forty-nine states and the District of Columbia require athletic trainers to hold the Board of Certification credential of “Athletic Trainer Certified” ().
Personal trainers are not health care providers, they are fitness coaches. This career category has less regulation, fewer established requirements, and does not require a college degree. Personal trainers do occasionally work with athletes, but they perform a very different role than athletic trainers.
