OET vs IELTS: Comparison of Scores, Difficulty and Regulator Rules

Two United Kingdom regulators publish both requirements, which makes them the clearest available comparison. Read across each row rather than down the columns.

• Nursing and Midwifery Council: Writing is held one step lower in both tests.
• General Medical Council: Every area held at the same level, with an extra overall figure on IELTS.

The shape of the two rows is the useful finding. One regulator holds writing a step below everything else in both tests; the other holds every area at the same level and adds an overall figure on IELTS only. That pattern belongs to the regulator, not to either examination — which is exactly why a general oet vs ielts comparison misleads.

Putting the scores next to each other invites a translation that does not exist. There is no published formula that maps an oet score to ielts bands. The two tests report on different scales, one in grade letters over a numeric range, the other in half-band increments: and no awarding body publishes an equivalence between them.

What the table above provides instead is a regulator-anchored pairing: for that body, those two requirements are treated as equally sufficient, which is a statement about that regulator's policy rather than about the two scales. Reading it as an oet score to ielts conversion in general would be a mistake, because a different regulator may pitch the two requirements at different relative levels and frequently does.

There is one more asymmetry worth planning around. The Nursing and Midwifery Council states that level 7 in all areas on IELTS may be achieved over two sittings, and it also publishes conditions for combining two OET sittings. Whether a near miss can be repaired by resitting one component, or requires the whole paper again, is a question for the regulator in both cases.

Ranking the two by difficulty assumes a single candidate. In practice the OET writing task is a professional document, a referral, advice, or a letter of transfer or discharge — and the speaking task is a role-play in the candidate's own field, while listening runs on generic healthcare topics accessible across all professions. A working clinician has done those things thousands of times in another language. The academic alternative asks for a different register altogether.

That is why the difficulty question keeps producing contradictory answers in forums: both camps are right about themselves. The way to convert it into an answerable question is to look at the four sub-tests and ask which one you would fail first. Then check what your regulator demands in that specific area, in both tests, and pick the paper where that single weakest area has the lower bar.

For nursing applicants that calculation is usually short. Choosing oet or ielts for nurses registering in the United Kingdom means comparing grade C+ in writing against a 6.5 in writing, with the other three areas held level in both, so the decision rests on reading and listening format rather than on writing at all. For doctors under the same national regulator the bar is flat across all four in both tests, and the extra overall requirement on IELTS is the only structural difference.

When the two requirements are genuinely close, two operational details tend to settle it. The first is turnaround. The OET is delivered on paper, on computer and at home, and the awarding body states results are typically available within 6 days for the computer and at-home formats against 12 days for paper. If a registration window is measured in weeks, a six-day difference is not a detail.

The second is destination. Cambridge English names the NMC, GMC, AHPRA, ECFMG, CGFNS and FMRAC among the bodies accepting the OET, and there are more. IELTS Academic is accepted far beyond healthcare, which matters if the same certificate has to serve a visa or a university application as well as a registration. Someone weighing oet or ielts for nurses who also needs a study route may find the wider-purpose test is worth a slightly higher bar.

Neither tie-breaker outranks the requirement itself. If a regulator names only one test, the comparison is over before it starts, and the only remaining question is which sitting format gets the result back in time.
