Your questions answered

    You need to be at least an Affiliate member to apply for Chartered status. If you’re not yet a member, you can join IOSH and then apply for Chartered status once you meet the requirements.

    While most Chartered Members hold a degree-level qualification, we recognise that extensive professional experience can be equivalent. If you have significant senior-level experience without formal qualifications (at UK level 6 or equivalent), contact our Professional Standards team to discuss your situation.

    We provide comprehensive guidance to help you prepare a strong application. If your application is unsuccessful, we provide detailed feedback and you can reapply.

    Yes. CMIOSH is an international qualification and we welcome applications from members worldwide. The requirements are the same regardless of location.
