Where this course can take you

Jobs this qualification is a recognised route into, and the study that can follow it.

Jobs you can do with it

  • Ship Captain

    Ship captains command a vessel and its crew, carrying legal responsibility for everyone aboard, the cargo and the ship itself.

    What else you need

    The diploma must be completed with an AMSA-approved training provider. It is only one requirement for an AMSA Master certificate of competency: you also need extensive qualifying sea service, a prior certificate, medical fitness and an oral exam. The award alone confers no certificate. This catalogue groups awards: verify the chosen provider, programme and intake; the family-level link is not confirmation that every offering is approved.
