OET Scores: 0–500, A–E and the Grade You Need

The big picture

• OET scoring (0–500 + A–E)
  • Per sub-test — A score and grade for each of the 4 skills
  • 0–500 scale — In 10-point increments
  • A–E grade — Mapped from the numerical score
  • Grade B ≈ 350 — A common regulator requirement

A score and grade per sub-test

OET reports a numerical score from 0 to 500 (in 10-point steps) for each of the four sub-tests, mapped to a letter grade A to E. There's no single overall score — your Listening, Reading, Writing and Speaking are each graded separately.

Grade B is the usual target

Many healthcare regulators and visa routes require Grade B (a score of about 350) in every sub-test. Because each skill is judged separately, your weakest sub-test is the constraint — a strong Reading can't rescue a Speaking below B.

Fix the weakest sub-test

Since every skill must clear the bar, identify your lowest sub-test and focus practice there. For most candidates that's Writing or Speaking (the profession-specific, human-judged ones), so targeted work on task selection and communication pays off most.

Check the exact requirement and retake if needed

Requirements differ by regulator, country and visa route, so confirm the exact grade you need before booking. If one sub-test falls short, you can retake — and in some cases combine sub-test results across sittings (check your authority's rules).

Test yourself before you move on

Re-reading a note feels like learning and produces almost none. The retrieval below is what actually builds the memory, so cover the map above and answer these from memory — out loud or written down, not in your head, because "I know this" is the feeling that fails under exam pressure.

1. Without looking: what is Per sub-test, and how does it connect to OET scoring (0–500 + A–E)?
2. Without looking: what is 0–500 scale, and how does it connect to OET scoring (0–500 + A–E)?
3. Without looking: what is A–E grade, and how does it connect to OET scoring (0–500 + A–E)?
4. Without looking: what is Grade B ≈ 350, and how does it connect to OET scoring (0–500 + A–E)?

Anything you could not produce is the part of this note you have not learned yet — regardless of how familiar it felt while reading. Re-read only that node, then re-test the whole set. Testing the whole set matters: recalling one idea in isolation is easier than recalling it among 4 competing ones, which is the situation the exam actually puts you in.

When to come back to this note

Spacing is not a scheduling detail, it is the mechanism. Meeting this material again just as it starts to fade forces the effortful retrieval that consolidates it, which is why a note reviewed four times across three weeks outlasts the same note read four times in one evening. The built-in scheduler resurfaces these questions at widening intervals for exactly that reason — the prompt arriving when you feel you have half-forgotten is the system working, not failing.

A practical rhythm for OET scoring (0–500 + A–E): today, again tomorrow, then after three days, then after a week. If you fail a review, shorten the next interval rather than re-reading the note end to end — the failure identifies the gap precisely, and re-reading everything wastes the diagnosis.

Then apply it under pressure. Knowing a concept in isolation and using it in a timed paper are different skills, and only the second is examined. There are 10 free OET practice tests here covering 258 questions — counted from the test files, not estimated. Take a full timed OET mock →
