What is the difference between chiropractor and chiropractitioner
The words seem to be used as synonyms in some quarters (even though chiropractitioner is not in the online English dictionaries), but if you happen to be in Germany:
in Germany, a chiropractor and a chiropractitioner are very different. In that country a person who uses the title chiropractor will have successfully completed a course of study, usually of a minimum of five years, at a college/university accredited by the European Council on Chiropractic Education (ECCE). On the other hand, a chiropractitioner (also called a Heilpraktiker) usually has no formal qualification in chiropractic and at most may have completed a series of weekend seminars (personal communication, President, German Chiropractic Association).
