To obtain a naturopathic medical credential (ND), students must have three years of pre-medical sciences at a university followed by successful completion of a 4-year-full time program at an accredited school of Naturopathic Medicine. This includes more than 4,500 hours of classroom training and 1,500 hours of supervised clinical experience.

To be licensed, NDs must pass NPLEX board exams that are written after the 2nd year and 4th year of study.

There are five accredited naturopathic schools in North America:
Toronto ON, Kenmore WA, Portland OR, Tempe AZ, Bridgeport CT.
