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.
