OH Learning is an international qualifications scheme administered by the Occupational Hygiene Training Association (OHTA). Examining boards from across the world have come together to agree a common framework of qualifications. The courses cover the core science and practice of occupational hygiene at a variety of levels, from foundation through to advanced.  Examinations, though optional, allow students to prove competency and work towards qualifications such as the International Certificate in Occupational Hygiene (iCertOH).  NZOHS is an approved training provider for OH Learning courses.
