A PRN (pro re nata) Athletic Trainer generally works on an as-needed basis, meaning shifts can vary depending on the needs of the employer, athletic events, or coverage requirements. Flexibility is key, as you may be called upon to cover clinics, practices, games, or even fill in for other staff at short notice. This role is ideal for professionals seeking variety or supplementary income, and it often provides exposure to multiple sports teams, healthcare settings, or organizations. While hours may fluctuate weekly, the flexibility and experience gained can lead to broader networking opportunities and may support advancement into full-time or specialized positions.
