How to calculate OET score: treat each sub-test separately. Listening and Reading raw marks are converted to a 0–500 scale, while trained assessors score Writing and Speaking against set criteria and convert those marks to the same scale. There is no combined total, so every sub-test carries its own grade.

Most candidates search for this because their result looks nothing like a school grade. Instead of a percentage you see four numbers between 0 and 500, each paired with a letter from A to E. Understanding how those numbers are produced helps you set realistic targets, choose which sub-test deserves extra study time, and judge whether a retake is worthwhile. This guide walks through each conversion, shows what Grade B really requires, and explains how boards read the figures.
The Occupational English Test, often searched as what is OET, is an English language test built for healthcare professionals such as nurses, doctors, dentists and pharmacists. Unlike general English exams, every task uses clinical settings: patient consultations, referral letters and handover notes. That context shapes the scoring. Assessors judge whether your English works in a real workplace, not whether you can produce elaborate vocabulary, so the criteria reward clarity, structure and an appropriate tone over complexity.
A quick note on terminology, because search results mix topics. In chemistry, what is OET in organic chemistry usually points to the ethoxy group, normally written OEt, which has nothing to do with this exam. If you are reading about grades, boards and sub-tests, you are in the right place. Official information about the test is published on the Cambridge English OET pages, and your own results appear in your online OET account once they are released.
Before diving into the maths, it helps to know the big picture. Every sub-test result is reported as a score from 0 to 500 in steps of ten, then mapped to a grade. Candidates aiming for Grade B, the target most boards use, need a score of at least 350 in each sub-test. For a deeper walkthrough of targets and strategies, read our guide to the OET Grading System and the tips for reaching Grade B in every sub-test.
The fastest way to see scoring in action is to sit realistic papers under timed conditions. Our oet sample test page explains what each paper looks like, and the free listening quizzes linked below let you practise marking yourself. Working through an oet english test sample or several oet sample tests gives you raw marks that you can convert using the rules in this article, which turns abstract band descriptions into numbers you can track week by week.
Keep one caution in mind as you read. OET does not publish a complete raw-to-scaled conversion chart for every test version, so any calculator you find online, including the approximations in this article, is an estimate. Treat estimates as a planning tool, not a guarantee. The only figure that matters to a board or employer is the official result in your OET account, so use your own calculations to prepare, then trust the official score.
You complete Listening, Reading, Writing and Speaking. Each one is marked on its own, so a weak result in one area never lowers or raises another.
Listening and Reading answers are checked against a mark scheme. Each correct answer earns one mark, and your raw total out of 42 is recorded for conversion.
Trained assessors apply published criteria to your letter and your role-plays. Each criterion receives its own score, and the criterion scores are added together.
Raw marks and criterion totals are converted to a score between 0 and 500, reported in steps of ten, so all four sub-tests share the same scale.
Each score falls into a band: A 450–500, B 350–440, C+ 300–340, C 200–290, D 100–190 and E 0–90. Your regulator then compares those grades with its requirement.
OET score is calculated by converting performance in each sub-test onto a 0–500 scale, reported in steps of ten. Listening and Reading are objectively marked, so your raw number of correct answers is converted. Writing and Speaking are marked by trained assessors against published criteria, and their criterion scores are combined and converted. Each of the four results stands alone, which means a strong Speaking score cannot rescue a weak Writing score.
For Reading, the paper has 42 questions across three parts and a 60-minute limit. Part A has 20 short-answer items to finish in 15 minutes, Part B has six workplace extracts, and Part C has 16 questions on two longer texts. Every question carries one mark, and there is no negative marking. Your raw total out of 42 is converted to the 0–500 scale. Widely cited guidance puts about 30 correct answers at the 350 mark, the Grade B threshold.
That benchmark answers the common question of how to calculate OET reading score at home. Count your correct answers, then compare the total with the rough anchor: 30 out of 42 is roughly 350. Because scores are reported in steps of ten, a single extra question can occasionally decide between Grade B and C+. These figures are estimates, since difficulty varies between versions, but they let you judge whether a practice paper is trending toward your target.
Listening works in a similar way. The test lasts around 45 minutes and contains 42 questions. Part A has two consultation extracts with 24 note-completion items, Part B has six short workplace extracts, and Part C has two presentations or interviews with 12 questions. Spelling counts in Part A, so a misspelled medical term can cost a mark. Your raw score out of 42 is converted to the 0–500 scale, and about 30 correct answers is again the figure most often linked to 350.
Writing is one task, usually a referral or discharge letter, completed in 45 minutes including five minutes of reading time. Assessors score six criteria: Purpose, Content, Conciseness and Clarity, Genre and Style, Organisation and Layout, and Language. Purpose is marked out of three, while the other five are marked out of seven. The totals are then converted to the 0–500 scale. Studying an oet writing sample, or a tutor-annotated e2language oet writing sample, shows how each criterion is applied.
Speaking lasts approximately 20 minutes and includes two role-plays in which you play the healthcare professional while an actor plays the patient or carer. Assessors score two groups of criteria. Linguistic criteria such as intelligibility, fluency, appropriateness of language and resources of grammar and expression are each marked out of six. Clinical communication criteria such as relationship building and information giving are each marked out of three. Hearing an oet speaking sample shows how a confident role-play balances both groups.
Once all criteria are marked, the totals are mapped onto the same scale and grade bands: A is 450–500, B is 350–440, C+ is 300–340, C is 200–290, D is 100–190 and E is 0–90. Notice that B ends at 440 and A begins at 450 because scores move in tens.
There is no averaging across sub-tests and no overall result, so you compare each of your four numbers with the requirement of your own board or council. Searches such as what is oet chem often come from people mixing up the ethoxy group in chemistry with this exam, and our certification guide covers the healthcare certificate itself.
Start with a full timed paper and mark it honestly. Write down the number of correct answers for each part, then add them for a total out of 42. Compare that total with the rough anchor of 30 for 350. If you land on 27, you are about three questions from Grade B, which is a very different problem from being fifteen questions short, and it tells you whether to adjust technique or rebuild skills.
Next, record where marks were lost. In Reading Part A, missed marks usually come from skimming rather than scanning. In Part C they come from distractor options. In Listening Part A, spelling and unfamiliar drug names are typical culprits. Track errors by part across three or four papers and a pattern appears. Repeating that cycle with each oet practice test turns raw marks into a clear weekly plan, and every oet exam practice test becomes more useful.
To estimate a Writing score, use the six criteria as a rubric. Give yourself a mark for Purpose out of three, then score Content, Conciseness and Clarity, Genre and Style, Organisation and Layout, and Language out of seven each, for a maximum of 38. Be strict: a letter with a vague opening sentence rarely earns full Purpose marks. Higher totals point toward Grade B, but OET does not publish a conversion, so treat any link as a rough guide.
Compare your letter with an oet writing sample at Grade B level. Look at what the sample leaves out as much as what it includes: irrelevant patient details are cut, the reader's needs come first, and the language is concise. Ask a teacher or peer to score your letter independently, because self-marking tends to be generous. Two or three scored letters each week give far more feedback than ten unmarked ones.
Speaking is harder to self-score, so record your role-plays on your phone and play them back with the criteria beside you. Score intelligibility, fluency, appropriateness of language and grammar out of six, then the clinical communication items out of three. Listen for filler words, long pauses, medical jargon used with a patient, and missed chances to check understanding. A friend playing the patient can add useful notes about whether they felt heard.
Watching an oet speaking sample helps you calibrate. Notice how a strong candidate opens with a greeting and a purpose, uses plain words for the patient, invites questions and summarises at the end. Then run a role-play yourself and note which behaviours you missed. If you are a nurse, an oet mock test for nurses with ward handover and discharge scenarios will feel much closer to what you will face on the day.
A B score in OET is any sub-test result from 350 to 440 on the 0–500 scale. Many boards ask for B in each sub-test, though some accept a lower grade in Writing, so confirm the exact requirement with your own regulator before you book.
You check your OET score by logging in to your online OET account once results are released, where each sub-test score and grade is displayed. Release timing depends on the format. OET on Computer results can arrive as little as 48 hours after all four sub-tests, with 95% released within six calendar days, while OET on Paper results are released from 13 days after the test outside India and the Philippines.
Your result shows four scores between 0 and 500, each with a grade letter. It does not show a pass or fail, because OET has no universal passing score. Instead, the board, council or employer that asked for OET sets its own minimum. A nurse registering with one body and a doctor registering with another may need entirely different results, so always check the current requirement with your own regulator before booking a test or celebrating a result.
Readers sometimes arrive after typing queries such as what is oet chemistry. If you wanted the healthcare exam rather than the chemical term, that page is our release-date guide, and it lists when results appear for each test format. Knowing the expected date matters because many registration applications have fixed deadlines, and a late result can push back your start date at a new hospital by weeks.
One recent change affects how you share your results. OET stopped issuing digital badges on 1 September 2026, so employers and boards cannot rely on a badge link any longer. If an organisation asks for proof, follow the instructions that organisation gives for receiving your official result. Keep a screenshot of your results page for your own records, but remember that receiving organisations generally want the official route rather than an image you send them yourself.
Identification matters too. OET requires the identification recorded in your booking account to match the identification you present on test day, so check that the name on your account matches your passport or other accepted ID exactly. A mismatch can cause serious problems on the day, and it is easy to avoid. Review the ID guidance on the OET support site well before your booking, not the night before your test.
If your result falls short, you may not need to retake everything. OET permits individual paper sub-test bookings after a previous full OET test, subject to venue availability and acceptance of partial results by the receiving organisation. That second condition is crucial. Some regulators accept results combined from separate sittings, while others insist on a single sitting. Confirm the rule first, because retaking one sub-test that your board will not combine would waste both time and money.
Plan around booking deadlines as well. Bookings for OET on Computer at a venue and OET@Home close seven days before the test date, while OET on Paper bookings close 24 days before. If you need results by a registration deadline, count backwards from that date using the release times above and add a buffer for unexpected delays. Starting this calculation early prevents the common mistake of booking a test that can never produce a result in time.
OET is graded A to E per sub-test, and each board or council decides which grades it accepts. Many bodies ask for at least a B in every sub-test, while some regulators accept C+ in Writing. In the United States a growing number of credentialing and licensing organisations recognise OET, but requirements differ by state and profession, so always read the current policy of the organisation that will receive your results.
Consider an example. A nurse scores Listening 380, Reading 350, Writing 330 and Speaking 360. Listening, Reading and Speaking all sit in the B band, while Writing falls in C+ (300–340). If the board asks for B everywhere, only Writing needs a retake. If it accepts C+ in Writing, the candidate is finished. Because nothing is averaged, the high Listening result of 380 does not lift the Writing result by even a single point.
Another example shows how close the boundaries are. A candidate with a Reading score of 340 is in C+, while one with 350 is in B, only ten points apart. That gap equals one step on the reporting scale and may represent a single question in Listening or Reading. This is why borderline candidates sometimes feel unlucky, and why building a cushion of 20 to 30 points above 350 in practice papers is a wise way to protect yourself against a difficult paper.
Validity is the next question. The authority receiving your OET results decides how long it recognises them, so there is no single expiry date. Some organisations accept results only from a fixed recent period, such as two years, while others set different windows. Before paying for a retake or booking a test far ahead of a licensing application, check the regulator's official website for its current policy, and note the date you checked so that you can spot changes later.
Different professions face different targets. OET offers profession-specific content for 12 healthcare professions, including nursing, medicine, dentistry, pharmacy and physiotherapy, but the scoring scale is identical for all of them. A pharmacist and a nurse who both score 350 in Reading have earned the same grade, although their regulators may still ask for different minimums. Check whether your body states requirements per sub-test or demands that all four be achieved in one sitting.
Sub-test balance matters in preparation. Many candidates find Writing the hardest to lift because it depends on selecting relevant case notes, not just on grammar. Others struggle with the speed of Listening Part A. Compare your four scores and put extra time into the lowest one, because it will most likely decide whether you meet the requirement. If you are working out how to prepare for oet, our how to prepare for oet guide lists resources by sub-test.
Finally, be careful with unofficial advice in forums. Requirements change, boards update their policies, and what worked for a friend registering two years ago may not apply to you. Always check the current official statement from your regulator, then use your OET sub-test scores to plan. Our related guides on acceptance, such as whether OET is accepted in Ireland, show how differently regulators phrase their rules even when they use exactly the same scale.
Before test day, convert every practice paper into a scaled estimate, record it, and aim for at least 370 to 380 so that you keep a margin above 350. Practice becomes useful only when you measure it. Keep a simple spreadsheet with four columns, one for each sub-test, and add a new row after each timed paper. Within three weeks the trend lines will show which skill needs attention and which one is already safe.
A sensible rhythm is two full-length timed papers per week in the last month, with the remaining study time spent on weak parts. For Listening and Reading, mark immediately and review every error. For Writing and Speaking, get feedback from a teacher or a study partner who knows the criteria. Use an oet practice test or an oet exam practice test from reliable sources, and avoid unverified materials that may follow an outdated format.
Nurses should choose scenarios from their own profession. An oet mock test for nurses typically features a ward discharge letter, a wound care consultation or a medication adherence role-play. Practising those exact situations builds vocabulary and confidence, and it makes your Writing letters more relevant, which feeds directly into the Purpose and Content criteria. Doctors, dentists and pharmacists should do the same with cases taken from their own daily work.
Practise timing as seriously as content. Reading Part A allows only 15 minutes for 20 items, so rehearsing under that limit matters. In Writing, spend the five reading minutes selecting information and planning your paragraphs instead of starting immediately. In Speaking, use your preparation time to note the patient's likely concerns. Candidates who lose marks usually lose them through rushed organisation, not through a lack of vocabulary or grammar.
In the last week, shift from learning to rehearsing. Confirm your booking details, test format, venue or home setup, and acceptable ID. For OET@Home, check your equipment and testing space in advance. Sleep properly, eat before the test, and avoid last-minute cramming of new vocabulary. A calm candidate reading a Part C text carefully will usually outscore an exhausted one who memorised twenty extra phrases and then misread the question.
After your result, use the numbers. Compare each sub-test with your board's requirement, calculate the gap in points, and decide whether you need a full retake or an individual sub-test booking where your regulator accepts it. If you missed by ten or twenty points, targeted work on one criterion, such as Language in Writing, could be enough. If you missed by 100 points, plan a longer study cycle with more feedback.
Finally, keep the process in perspective. OET is designed to test the English you actually use at work, so improving your handover clarity, your explanations to patients and your note summaries helps in both the exam and your career. Treat every score as feedback rather than a verdict. With a steady routine, accurate self-scoring and the right board target, calculating your OET score becomes a planning tool instead of a source of anxiety.
