Just like your primary care physician, doctors of chiropractic must complete a rigorous training program in order to become licensed practitioners. Although the standards for chiropractic practice vary depending on the country, the U.S. has consistent regulations for professionals and requirements for educational qualifications, which are set by the Council on Chiropractic Education. In order to receive a DC (Doctor of Chiropractic) degree, students must first fulfill extensive undergraduate programs centered on anatomy, physics, and chemistry before programs on advanced clinical sciences. DC students practice and refine their skills, often in clinical internships to fulfill the minimum requirement of 1,000 hours of supervised training. Before entering the field, all doctors of chiropractic must pass both state and national board exams.
