IMCA runs a certification scheme for the following three positions only:
- Air Diving Supervisor (ADS)
- Bell Diving Supervisor (BDS) – For more information on the now revised examination can be found here
- Life Support Technician (LST) – For more information on the launch of the revised IMCA LST exam here
For any other positions, please see our diving training and certification page for details on relevant issuing bodies and IMCA guidance.
The certification process can be summarised as follows:
- Meet the entry level criteria (such as holding a recognised diver certificate)
- Complete IMCA-approved training (trainee air, bell or ALST)
- On successful completion of a course, work at the trainee/assistant level, gaining supervised hands-on experience offshore. Acceptable experience can only be gained and logged while working for a contractor member of IMCA’s Diving Division.
- Be put forward by the employer to sit and pass the relevant IMCA examination(s) (see below) to become an IMCA-certified diving supervisor or life support technician.

Candidates must complete the application process within 120 days of application. Failure to do so will require them to reapply in full and pay another application charge. If IMCA has requested more information from the applicant and it has not been provided within 120 days of the application, the candidate will have to reapply in full and pay another application charge.

Once a trainee offshore air or bell diving supervisor/assistant life support technician has logged the required hours, their employer can put them forward to IMCA with a recommendation that they be entered for the relevant examination. IMCA does not accept examination applications from private individuals.
There are multi-choice examination modules for air diving supervision, mixed gas/bell diving supervision and life support, as well as optional legislation modules which candidates can choose to take relevant to the parts of the world in which they might work.
A list of exam dates and locations, and provisional exam dates and locations, can be found here.
On demand exams will still be available but there will be an additional charge to cover the exam center’s costs. This will likely to be in the region of £1000.00 and will be on top of any IMCA exam fee listed above. On demand examinations are held around the world – IMCA has established arrangements with venues in more than 35 countries and liaises with relevant organisations in other locations as required to identify venues which are reasonably convenient for candidates.
IMCA only accepts candidates for IMCA examinations who have been nominated by contractor members of the IMCA Diving Division. Candidates for IMCA examinations need to be put forward by nominated individuals within their companies, who will have access to the relevant forms, fee schedules and contact details.
Candidates must achieve a minimum of over 70% in each of the sections and must also achieve a minimum of 75% over the whole examination to pass.
