Quick answer
Internationally trained pharmacists need Grade B (350) in each of the four OET sub-tests, at one sitting, for GPhC registration in the UK. The GPhC has no Grade C+ concession. PBA (Australia, via AHPRA) has accepted Grade C+ (300) in Writing since 18 March 2025, with Grade B in Listening, Reading and Speaking. PSI (Ireland) also accepts OET; check its page for current minimums. The most distinctive OET challenge for pharmacists is the counselling letter — written to a patient, not a clinician — requiring full register shift away from pharmacological terminology.
