OET Score and Grades: Conversion, Pass Mark and What Regulators Read

Oet grades run from A at the top to E. Three of the six boundaries are published by the Nursing and Midwifery Council and are reproduced here for that reason; the other three are not, and no figure is invented to fill the gap.

The practical reading of oet grades is narrower than the table suggests. Most registration requirements name a single letter and apply it to every sub-test, so the working question is rarely which band a score sits in but whether all four sit at or above the letter the regulator named.

People look for an oet score conversion for two different reasons, and only one of them has an answer. The answerable version is regulatory: a regulator that accepts both the OET and IELTS Academic publishes what it wants in each, so its two requirements can be set side by side. The Nursing and Midwifery Council asks for grade B in reading, listening and speaking and C+ in writing on one test, and at least 7 in reading, listening and speaking with 6.5 in writing on the other. That is a usable mapping, because one body wrote both halves of it.

The unanswerable version is psychometric: there is no published equation that turns a grade into a band. An oet score conversion table circulating without a named source is somebody’s arithmetic, and a registration application is a poor place to test it.

The distinction matters when choosing which test to sit. If a regulator states both requirements, comparing them is legitimate and useful. If it names only one test, the conversion question does not arise, because the other result will not be read.

There is no single oet pass mark. The test reports a score; the threshold is set by whoever reads it. The General Medical Council asks for the medicine version of the test with at least grade B in each testing area. The Nursing and Midwifery Council accepts C+ in writing while asking B elsewhere. Same certificate, two different verdicts, and neither is the test’s doing.

This has a scheduling consequence worth planning around. Because the oet pass mark is external, a candidate who is close on one sub-test should find out how their specific regulator treats combined sittings before booking a full retake. At least one publishes the combinations it will accept, with a worked example of a pair it rejects. Others do not allow combining at all.

The Nursing and Midwifery Council publishes a worked example of a pair it will not accept, and it is worth reading closely because it shows how the arithmetic actually runs. In its illustration a candidate holds C+ in listening, B in reading, B in writing and B in speaking at the first sitting, then C in listening, B in reading, C+ in writing and B in speaking at the second. The combination fails on listening alone: one sitting is below the minimum for that domain, and the required grade B in listening is never reached in either. Every other domain in that example is fine, which is precisely the trap: three strong columns do not carry a fourth.

Read against that example, the rule the regulator is applying becomes clear. Combining sittings does not mean taking the best of each; it means each domain must clear its own bar somewhere, and no domain may fall below a stated floor in the sittings being combined. A candidate planning a second attempt should therefore know which single domain is carrying the application before booking anything.

The Australian regulator is a live example of why a figure should be read at source rather than copied: it accepts the test and states that changes to its minimum scores took effect on 23 April 2026. Any table that quotes an older Australian number is now wrong, including tables that were right when they were written.
