Chiropractors have a doctorate degree and must complete a four-year chiropractic program (in addition to undergraduate prerequisite studies) including a clinical internship. The course load is roughly equivalent in hours and credits to the training required for an M.D. The focus of chiropractic education is on the function of the body and nervous system. The science of chiropractic requires special emphasis on anatomy, normal and adaptive physiology, biomechanics, neurology, x-ray and many different spinal adjusting techniques.
To be licensed as a Doctor of Chiropractic, each candidate must pass a series of rigorous National Board Examinations in addition to an individual State Board Examination. Chiropractors must also attend continuing education classes to retain their licensure.
