Many chiropractic programs require prospective students to have a minimum of three years of undergraduate education or 90 semester hours, and some programs require applicants to have bachelor's degrees, according to the Association of Chiropractic Colleges. For every program, applicants must complete a certain number of prerequisite courses as determined by the Council on Chiropractic Education.
Doctor of chiropractic program applicants must maintain a 3.0 grade point average on a 4.0 scale for undergraduate hours, and at least 24 of the undergraduate hours must be in life and physical science courses, explains the Association of Chiropractic Colleges. At least half of these science courses must have substantive laboratory components. Applicants must take coursework in biological sciences, chemistry and physics.
At least six of the chemistry semester hours a chiropractic school applicant takes must have a lab component, states the Association of Chiropractic Colleges. An applicant must take three hours of general or inorganic chemistry, six semester hours of organic chemistry or biochemistry, and three semester hours of a chemistry elective. To meet the physics requirements, applicants must take two unduplicated physics classes with corresponding labs. Alternatively, applicants may take three semester hours on physics with a corresponding lab and also take three semester hours in kinesiology, statistics or exercise physiology. In some states, applicants must take Physics I and II.
Doctor of chiropractic program applicants also need to take English, social sciences and humanities, and psychology classes, notes the Association of Chiropractic Colleges. Each chiropractic school has its own requirements for the number of credits that applicants must earn in these subject areas. In each of these subject areas, along with the required science subject areas, chiropractic schools do not accept grades below 2.0 on a 4.0 scale.
