To become a chiropractor, you are required to meet some of the most demanding educational requirements of any health care profession. Most chiropractors have already taken close to four years of pre-med undergraduate courses before they even apply to chiropractic college. This includes biology, psychology, physics, and chemistry. If you are accepted into an accredited chiropractic college, then the really demanding work begins. You’ll work through four academic years, which includes learning the hands-on adjusting techniques that will become a big part of your practice. The complete educational curriculum for chiropractors includes minimum classroom, laboratory, and clinical experience of 4,200 hours. Chiropractors have classroom requirements equal to or greater than traditional medical professionals. This in-depth training allows Doctor of Chiropractic to be considered primary care physicians. Primary care physicians are considered point of entry physicians and do not require a referral.
