OET rewards familiarity with its specific format more than raw English ability — nurses with strong clinical English routinely lose marks on OET simply because they haven't practised the task types. This guide covers how to prepare for each sub-test, the mistakes nursing candidates make most often, and how long preparation typically takes.
How Much Preparation Time Do You Need?
| Starting Point | Typical Preparation Time |
|---|---|
| Strong clinical English, no OET-specific practice | 3–4 weeks |
| Solid general English, weaker in one sub-test | 6–8 weeks |
| General English needs broad improvement | 3+ months |
A commonly recommended baseline is a 4-week structured study plan for candidates who are already working clinically in English, combining self-study for Listening/Reading with dedicated writing correction and speaking practice. Treat this as a typical range, not a guarantee — some candidates need two or three sittings regardless of preparation time, most often because of Writing or Speaking format issues rather than English ability.
Listening
What it tests: Two recorded consultations (note-taking) and a longer healthcare-related talk or interview.
Common mistakes:
- Not previewing the questions before the audio starts — this is one of the single biggest cost points in Listening.
- Trying to write full sentences instead of concise notes, and falling behind the recording.
- Losing concentration during the longer third part.
How to prepare:
- Practise note-taking speed with real OET-style recordings, not general English listening material.
- Read the question stems for each part before the audio begins — every time.
- Do timed full-length practice tests, not isolated exercises, to build stamina.
Reading
What it tests: Part A (expeditious reading across four short texts, separately timed at 15 minutes) and Parts B and C (longer healthcare texts, general comprehension).
Common mistakes:
- Overspending time on Part A and running out of time for Parts B and C.
- Reading passages in full before checking what the question is asking (slower and less accurate for Part A specifically).
- Guessing based on keyword-matching rather than actual meaning in Parts B/C.
How to prepare:
- Practise Part A under strict 15-minute timing until scanning becomes automatic.
- For Parts B and C, read the question first, then locate the relevant section — don't read the whole passage top to bottom.
- Review every practice test afterwards and identify why an answer was wrong, not just that it was wrong.
Writing
What it tests (nursing): A letter (commonly a referral, discharge, or transfer letter) written from case notes provided in the task.
This is where most nursing candidates lose marks — often candidates with excellent clinical English fail Writing because they don't follow OET's required letter structure or include information the task doesn't call for.
Common mistakes:
- Including every detail from the case notes instead of selecting only what's clinically relevant to the letter's stated purpose.
- Getting the letter structure wrong (missing a clear opening, unclear organisation of clinical information, weak closing).
- Running out of time because too long was spent reading/planning.
How to prepare:
- Learn and drill the standard letter structure: opening (reason for referral) → relevant clinical history and current status → purpose/request → closing.
- Practise selecting only clinically relevant case notes — this is a skill in itself, separate from English ability.
- Get every practice letter checked against OET's official assessment criteria (six criteria: appropriateness of language, comprehension of stimulus, general linguistic range, grammatical range, organisation and layout, and vocabulary) — self-assessment misses format errors most often.
Speaking
What it tests (nursing): Two role-plays with a trained interlocutor playing a patient, carer, or colleague, based on real clinical scenarios (explaining a procedure, managing a worried relative, breaking difficult news).
Common mistakes:
- Reading directly from the role-play card notes instead of using them as prompts for natural speech.
- Missing the specific "tasks" listed on the card (each role-play has required things to cover — missing them costs marks even if the conversation flows well).
- Sounding scripted rather than responding naturally to what the interlocutor actually says.
How to prepare:
- Practise role-plays out loud with a partner, not just silently reading through scenarios.
- Cover every bullet point/task listed on the role-play card, in a natural order.
- Record yourself and review — hesitation, unnatural pauses, and missed tasks are far more visible on playback.
Where to Find Official Practice Material
- oet.com — the official OET site sells official practice tests and sample materials, and is the only source guaranteed to reflect the current format and marking criteria.
- OET's official preparation portal includes free sample test material for all professions, plus paid full practice tests with model answers.
- Be cautious with third-party "OET practice" content — much of it is unofficial and can drift from the actual current format. Cross-check anything you study against the official OET website before relying on it.
A Simple Preparation Checklist
- Take one full official practice test cold, before any study, to identify your weakest sub-test.
- Spend the most preparation time on Writing — it's the sub-test most nursing candidates underestimate.
- Do timed, full-length practice tests regularly, not just isolated question drills.
- Get Writing and Speaking checked against official OET criteria — self-scoring is unreliable for these two sub-tests specifically.
- Re-confirm your target regulator's exact grade requirement before your final practice push, since Writing thresholds sometimes differ from the other three sub-tests.
