To prepare at Ball State for entrance into a chiropractic school, you will need to follow the pre-chiropractic curriculum which involves completion of either the pre-medical or biology major as well as specific elective classes. Many chiropractic schools require applicants to have a minimum of 60 total college credit hours but some require 90 credit hours. However, many states require that Doctors of Chiropractic also have an earned bachelor's degree in order to practice. Completion of a bachelor's degree is recommended.
