Quick answer: OET lets you book a single sub-test. But booking is not acceptance. Of the eight regulator doors on this page, exactly one accepts a single sub-test retake: the Nursing Council of New Zealand. The UK, Australia, Ireland and the USA all demand full sittings, for nurses and for doctors, and so does New Zealand’s Medical Council for doctors. Australia’s only single skill retake is the IELTS one, never OET.
You failed one sub-test. Maybe by ten points. And now the question burning in every group chat and every night shift break: do I need to resit all four, or can I resit one sub-test only?
Here is the trap nobody explains. OET will happily sell you a single sub-test booking. The button exists. The payment goes through. The seat gets booked. And then, months later, the regulator looks at your certificate and says: we need all four components from the same sitting. The fee is gone. The months are gone.
The verdict table. Verified, dated, complete.
| Your door | Regulator | Single sub-test retake | What is allowed instead |
|---|---|---|---|
| New Zealand, nurses | Nursing Council | Yes. The only yes on this page | Scores collected over more than one sitting, within 12 months of your first sitting, all sittings inside the three years before you apply |
| New Zealand, doctors | MCNZ | No. All four components in every sitting | Two full sittings within 12 months, with no component below 300 in either |
| Australia, nurses and doctors | AHPRA | No. The only single skill retake AHPRA accepts is the IELTS one, never OET | Two full sittings within 12 months, floors of 320, 340, 350 and 350 under the table from 23 April 2026 |
| UK, nurses and midwives | NMC | No. Both sittings must be full four sub-test sittings | Two full sittings within 12 months, floors of 300 in Listening, Reading and Speaking and 250 in Writing |
| UK, doctors | GMC | No. One sitting, same test, most recent attempt | Nothing. All four grade Bs together, or sit again |
| Ireland, nurses and midwives | NMBI | No. One test result only | Nothing. Grade B in three components and C+ in the fourth, in a single sitting |
| USA, doctors | ECFMG | No. One administration | Nothing. 350 in Listening, Reading and Speaking with 300 in Writing, together |
Read this line twice, because it saves exam fees
A single sub-test booking on the OET website is not proof that your regulator accepts it. OET is the test company. Your regulator is the judge. The test company sells seats. The judge sets rules.
One nurse books a Reading only retake for her Australian application, scores a beautiful 400, and AHPRA cannot use it, because her sitting did not include all four components. Fee burned, months burned, confidence burned. Match the booking to your regulator’s rule before you pay, every single time.
For the doctors, the door is simply harder
Every doctor route on this table says no. The GMC wants all four Bs in one test, from your most recent attempt. The ECFMG wants one administration. Australia allows two full sittings but never a lone sub-test. And New Zealand’s Medical Council, in its own policy revised November 2025, allows the two sitting club but demands all four components each time, with nothing below 300 in either.
One detail worth knowing, because it explains where the confusion comes from: MCNZ and AHPRA both accept the IELTS One Skill Retake. Neither accepts an OET equivalent, because OET does not have one that regulators recognise. A rule someone half remembers about retaking one skill is almost always that IELTS rule, wearing the wrong badge.
So the doctor’s strategy has no shortcuts: prepare all four to the level, and when one sub-test is the leak, fix that leak before the full resit, because you will be sitting everything again regardless.
For the nurses, three honest roads
Going to New Zealand? You hold the only golden ticket here. The Nursing Council lets your required scores be collected over more than one sitting, so the failed sub-test can be sat on its own, as long as everything lands within 12 months of your first sitting and all sittings fall inside the three years before you apply. This flexibility alone makes New Zealand the most forgiving door in the OET world.
Going to the UK or Australia? No single retake, but clubbing saves you: sit the full test again, and combine the two sittings. The rules, the floors, the windows, and the checker that tells you exactly what you need next time, are all here. → OET clubbing rules 2026
Going to Ireland or the USA? One sitting must carry everything. No retakes, no clubbing, no mercy. Your next attempt must be the complete one.
Before you book anything, run your numbers
Choose your profession and country, enter your scores, and see the verdict with every rule shown, pass or fail, verified from the official pages. → OET eligibility checker
And if this is your second or third attempt, read why the resits keep happening before you pay for another one. It is almost never your English. → Why students fail
Your next sitting should be your last one. Know your real level first, free. → Free practice tests
How this page stays accurate
Eight regulator entries sit behind this table, each read from that body’s own page on 2 September 2026, and the Medical Council of New Zealand’s on 4 September 2026, including the Medical Council of New Zealand’s policy revised in November 2025. One honest gap, named rather than filled: that MCNZ policy says nothing at all about OET@Home or remote testing, so this page does not claim it is accepted and does not claim it is refused. Confirm that one with the Council before you book. Everything else here comes from a page you can open yourself.
