The D.C. (Doctor of Chiropractic) is a 4 - year doctoral degree. Prerequisite for entry into the doctoral program, most chiropractic colleges require an undergraduate degree with rigorous science training in Anatomy, Biochemistry, Embryology, Microbiology, Physics, Physiology, Mathematics, and Statistics, virtually identical to the basic science requirements for entry into medical school. After being admitted to a chiropractic college, science training continues with Neuroscience, Physiology, Pathology, Clinical Medicine, and Physical & Differential Diagnosis. During the final 2 years of a 4 - year professional program, chiropractic education specializes in Musculoskeletal Conditions and Diagnosis, with a full year of Clinical Internship under the supervision of licensed D.C.’s, whereas in medical schools, specialization becomes directed more into Pharmacology and Surgery.
