You'll need to get a qualification that is recognised by one of the professional organisations for naturopathy.
The General Council and Register of Naturopaths (GCRN) is a professional body for naturopathy and recommends that courses should last at least 3 years, should involve attendance and not be done by distance learning alone.
You should also check the course content and how much of it includes clinical placements to get work experience.
You'll usually need:
- 3 A levels (with at least two in science-based subjects)
