Quick answer
For internationally trained paramedics, Grade B (350) in each of the four OET sub-tests is accepted by HCPC (UK, registered as Paramedic) and the Paramedicine Board of Australia (AHPRA). AHPRA lowered its OET Writing minimum from B to C+ on 18 March 2025 for the National Boards it lists; confirm the Paramedicine Board of Australia's current Writing minimum on its page. 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.
