How to Convert OET Scores to IELTS Bands (2025 Update)

Medical practitioners worldwide, particularly doctors and nurses seeking to practice in Australia, New Zealand, or the UK, tend to compare OET and IELTS scores. The confusion begins when registering for or processing a visa, and institutions refer to IELTS, even though the candidate has already taken the OET. As both tests aim for the same goal—English proficiency—the major question arises: Can the OET substitute for the IELTS?

The rationale for this comparison is straightforward: nurses don’t want to take costly exams over again when they already possess a current score in one of them. That’s why learning about IELTS vs OET band comparison goes beyond an intellectual exercise—it’s a time-saving strategy, avoiding delays, and registering successfully.

OET Vs IELTS

While there are no general conversion criteria adopted by all authorities, a common perception has developed over the years. An OET Grade A is generally regarded as equal to an extremely high IELTS score, nearly on a level of native ability.

An OET Grade B is generally understood to be equivalent to what the majority of licensing authorities require from IELTS test takers, at around the upper-intermediate to advanced level.

In the meantime, a C+ in OET is regarded as equivalent to moderate or borderline IELTS scores, and anything lower than this is usually regarded as inadequate for professional registration.

Institutions do not mathematically convert scores but match competency expectations. For instance, an OET Grade B implies that a candidate can communicate safely and confidently in a healthcare environment, which is commensurate with what IELTS demands of a person in the 7-band range. That is why numerous councils accept OET as a substitute for IELTS, even though they do not actually give conversion numbers.

Official Equivalency Chart (2025 Update)

OET Grade / Score	Approx. IELTS Band Equivalent
A (450–500)	8.5 – 9.0
B (350–440)	7.0 – 8.0
C+ (300–340)	6.0 – 6.5
C (200–290)	5.0 – 5.5
D (100–190)	4.0 – 4.5

How Institutions Interpret OET vs IELTS

Various organisations approach score interpretation in line with their needs.

In the UK, the Nursing and Midwifery Council (NMC) accepts OET Grade B in Speaking, Listening, and Reading, while granting C+ in Writing, which they equate to IELTS 7.0 overall with 6.5 in Writing.

The General Medical Council (GMC), responsible for doctors’ registration, is slightly stricter and expects Grade B across all four OET sections, which mirrors the requirement of IELTS 7.5 overall with no score lower than 7.0.

In Australia, both AHPRA and ANMAC consider OET B in all sub-tests instead of IELTS 7.0. But when it comes to immigration and permanent residency, nations like Canada and New Zealand prefer IELTS, particularly in the Academic or General Training mode. That is, OET may suffice for registration but not visa processing, depending on the route.

When to Use Conversion Over Retaking Exams

Not everybody wishes to—or can afford to—sit for another language test. There are a few situations where the application of OET to IELTS score conversion is preferable over retaking either exam.

If your OET results are good but the application portal only refers to IELTS, check if the institution accepts equivalency. Quite a few councils already do, even though the website may not show it. Occasionally, a quick supporting letter or explanation will suffice.

If you narrowly missed one IELTS sub-score—say, getting a Writing score of 6.5 when a 7.0 is needed—you can take OET and utilize the Writing grade to show comparable ability. Some professionals blend and match scores to establish competence across tests, particularly when institutions allow score comparison but not precise matching.

Also, if your deadline is looming, conversion is faster than arranging another exam time slot, waiting for the results, and risking another misfit.

Practical Examples and Use Cases

Consider the case of a nurse who got an OET Grade B in Speaking, Reading, and Listening but a C+ in Writing. If she were to seek registration in the UK, the NMC would still accept her, provided she fulfils the combined minimum requirement. There would be no need to retake the full exam.

Another instance is when a physician sat for IELTS initially and passed generally, but had poor Speaking. Rather than retaking IELTS, he took OET and managed to obtain a Grade B in Speaking, which he subsequently used to sustain his application in line with equivalency rules.

There are instances where candidates avoid taking IELTS in the first place by opting for destinations or routes that expressly accept OET without conversion, like specific nursing jobs in Australia.

These examples indicate that conversion isn’t theoretical—it’s actually a real-world strategy applied by professionals to simplify their registration process.

Common Misunderstandings About Equivalency

One of the largest myths is that OET Grade B is always the same as IELTS 7.5 and above. In fact, it varies from institution to institution. Some may consider it to be equivalent to 7.0, while others match it to 7.5. That is why assumptions are dangerous—clarification is always necessary.

Another misbelief is that OET is inherently easier than IELTS. Although OET utilizes common medical topics, scoring is very strict, particularly in Writing and Speaking. Test-takers who take it lightly tend to do poorly because they approach it lightly.

There is also uncertainty about whether OET is accepted for immigration. OET is not universally accepted by immigration departments, even though it is accepted for professional licensing. This implies that one could be registered as a nurse but still refused by visa rules if they do not offer IELTS or an alternative approved test.

Conclusion

Making the Right Test Choice

So, do you opt for OET or IELTS? The choice lies in your aim. If your main focus is professional registration in the healthcare sector, OET is generally more specific and easier to relate to, as it involves medical terms and situations you are already familiar with. But if you are looking for permanent residency or overall career prospects outside the healthcare sector, IELTS remains more widely accepted.

The best approach is not always to select one exam over the other but to use them both in combination if necessary. If you have a better performance in some areas on one test, utilize equivalency interpretations to your benefit. Numerous nurses have registered successfully by blending both results, and numerous physicians have utilized conversion rather than retaking stress-inducing tests.

In short, don’t simply pursue scores—play smart with equivalency.
