Quick answer
Internationally trained paramedics need Grade B (350) in each of the four OET sub-tests for HCPC (UK, registered as Paramedic) and the Paramedicine Board of Australia (AHPRA). The Writing sub-test is a single letter, usually a referral or handover after a pre-hospital assessment. Most marks are lost on Genre & Style: scene codes and drug shorthand left in for a reader who was never on scene.
