OET band scores explained (0–500 to A, B, C+, D)
How the OET 0–500 scoring works: band thresholds, what each regulator requires, and what your score report is really telling you.
OET reports two things for each of the four sub-tests:
- A numeric score from 0 to 500
- A band letter — A, B, C+, C, D, or E
The band letter is what most regulators actually use to gate registration. The numeric score gives you finer detail on where you sit inside (or near) a band.
This guide explains the mapping, what each band means, what most regulators require, and how to interpret your own score report.
The official band table
The mapping is uniform across all four sub-tests:
| Band | Numeric range | What it indicates | |---|---|---| | A | 450–500 | High proficiency. Effortless across professional contexts. | | B | 350–440 | Good proficiency. Communicates with confidence and clarity in clinical contexts. | | C+ | 300–340 | Adequate-plus. Generally effective but with noticeable gaps. | | C | 200–290 | Adequate. Manages most situations but struggles with complex content. | | D | 100–190 | Limited. Communication breaks down often. | | E | 0–90 | Very limited. |
The granularity inside a band varies — A is a single 50-point span, B is a 100-point span, C is a 100-point span — but the boundaries between bands are the lines that matter for registration purposes.
What do regulators require?
The most common requirement across regulators is:
Band B (350+) in each of the four sub-tests.
Some regulators add nuance:
- One C+ allowed, B in the others — UK NMC and some others, depending on the year and the role
- Two-sitting aggregation — UK GMC and some others let you combine your highest sub-test scores from two attempts within a 12-month window, provided each individual attempt has at least B in every sub-test on its own merit
- Stricter for Speaking — some regulators want B in Speaking specifically and slightly more relaxed thresholds in the other sub-tests
Always confirm with your specific regulator. The thresholds change as the test evolves and as professional standards are revised.
What does each band mean in practice?
Band B (350–440) is the "you can do the job" band. You can take a history, explain a treatment, and handle a difficult patient conversation in English. You will not be unintelligible, you will not blank, and you will not break down under clinical pressure. Most candidates aim for the middle of B (around 380–400) for a safe pass.
Band C+ (300–340) is the "you can mostly do the job, but examiners noticed gaps." Most often the gaps are: occasional grammar slips that distort meaning, fluency that wobbles under pressure, or empathy phrases that feel borrowed rather than natural. Some regulators accept C+ in one sub-test if the others are clean B.
Band C (200–290) is below most registration thresholds. You can communicate, but you would struggle in a real consultation with a frustrated patient or a complex case.
Band A (450+) is rare. It means an examiner couldn't find anything meaningful to mark you down on. Few candidates need A — they only need B.
The detail inside each band
Many candidates fixate on the band letter and ignore the numeric score. That's a mistake. The numeric score tells you whether you are:
- Coasting through the band (e.g. 410 in a B-required test) — you have headroom for a bad day
- Sitting at the edge (e.g. 350 — exactly the B threshold) — any wobble could push you to C+
- Just shy of the next band (e.g. 340 — one mark off C+) — worth a retake if you have time
If you scored 360 in Speaking and your regulator wants B, you passed. But if a single criterion downgrade in your next attempt would push you to 340, your "B" is fragile. The numeric score is your warning system.
What if you fail one sub-test?
The most common scenario: three Bs and one C+ in Speaking. Two paths:
- Aggregate — if your regulator allows two-sitting aggregation, retake just Speaking
- Resit — book a fresh sitting and re-take everything
Re-takes for individual sub-tests are allowed but not always cheap. Check the official OET site for current pricing.
How are the scores calculated?
For Listening and Reading, scoring is largely automatic — items are right or wrong, weighted, and aggregated. For Writing and Speaking, two examiners independently score against the rubric and the scores are averaged. If they disagree by more than a tolerance threshold, a third examiner re-scores.
For Speaking specifically, you are graded on the 9 OET communication criteria: four linguistic and five clinical. Each criterion is scored 0–5 by each examiner. The aggregate determines the 0–500 score.
This is also how OET Live scores your practice sessions — by mirroring the public rubric and grading each criterion independently.
Reading your score report
Your OET score report shows:
- The numeric score and band letter for each of the four sub-tests
- A small explanatory note for each sub-test
- Issue date and validity window
It does not show per-criterion sub-scores for Speaking and Writing — only the aggregate. That's frustrating if you want to know which criterion lost you marks. The OET Live practice tool shows you per-criterion breakdowns precisely because the official report doesn't.
