What is this?
Our Society, the ‘International Yacht Marine Certification Society” (IYM) operates its entire operations under a Quality Management System (QMS) that is in compliance with the International Standards Organisation (ISO) 9001:2015 amended. Part of this compliance involves full auditing procedures.
This is an important reference and enables us to gain recognitions from maritime administrations and marine industry bodies alike. Our Society is ISO 9001:2015 certified by the British Standards Institute (BSI) United State. The QMS together with the ISO, ensures that IYM and its Members operate to the highest standards possible. All our courses, and more importantly the Certifications that we issue, are under ISO 9001:2015.
This practise is most unusual for such courses and certifications. Some organisations will claim ISO:9001 adherence but often the reality is it is for a document management process or a similar back-office process instead of for actual operations and/or for Certification issuing.
