To obtain an athletic trainer internship, you need to be enrolled in an undergraduate or graduate program focused on sports medicine, physical therapy, or a related field. Having experience as a student-athlete is also very helpful and provides insight into effective training techniques, common sports injuries, and how they can be prevented. You should have strong observational skills and attention to detail because you need to continually assess the performance of the athletes, discuss issues with the coach or other trainers, and be able to determine when an athlete needs further medical assistance. Excellent verbal and written communication skills are also essential. Network with local coaches and sports teams to find athletic trainer internship opportunities.
