I have already commented once, but I thought that this paragraph taken from Palmer College's Website was relevant. They tell prospective student's that a Bachelor's degree is recommended. The statement is as follows---

"Please note: Individual licensing boards may require additional education prior to entering a chiropractic college. Florida, Kansas, Maryland, Montana, North Carolina, Rhode Island, Tennessee, West Virginia, Wisconsis, and the United States Virgin islands require a Bachelor degree in order to be certified. Although it is not a prerequisite for Admission, Palmer College of Chiropractic recommends students complete a Bachelors degree prior to entering the D. C. program. It is imperative that you confirm all information with the licensing board of the state, province or country in which you desire to be licensed."
