Naturopathic Medical training closely parallels that of medical doctors.  NDs must first complete a four year pre-med post-secondary education prior to being accepted into an accredited four-year program at an approved college of Naturopathic medicine.
There are seven accredited naturopathic medical colleges in North America. For a complete list, see CNPBC website.
During and following completion from an accredited naturopathic medical program, successful candidates must complete standardized examinations set by the North American Board of Naturopathic Examinatins (NABNE) in addition to jurisdictional licensing, set by the CNPBC in British Columbia.
NDs are also required to maintain their license by completing continuing education credits on a 2-year regulated cycle.
