OET Writing Retake: How to Pass on Round 2

Failing the OET writing sub-test is more common than most candidates realise — and it is almost always fixable. But only if you understand why you failed, rather than simply trying harder at the same things.

This guide is for candidates who have scored below Grade B (350) and are preparing to retake. It covers how to diagnose your failure accurately, the five most common failure patterns, and a structured preparation plan by timeline.

The Most Important Step Before Starting Preparation Again

Most retake candidates make the same mistake: they start preparing immediately, writing more letters, without first understanding which criteria pulled them below 350.

OET Writing is scored on 6 separate criteria. A score of 320 could mean:

• All six criteria at a moderate level, or
• Four criteria passing and two failing badly, or
• One criterion — content selection — dragging down the total

These are completely different problems requiring completely different preparation. Starting without this diagnosis means you may spend weeks improving a criterion that was already fine.

The 5 Most Common Failure Patterns

After analysing thousands of failed OET letters, five patterns account for the vast majority of below-Grade-B scores.

Pattern 1: No Clear Purpose in the Opening Sentence

What it looks like: “I am writing regarding Mrs. Chen, a 58-year-old retired teacher.”

The examiner cannot tell from this whether it is a referral, a discharge, or something else. The Purpose criterion is compromised from the first line.

The fix: The purpose must be explicit and specific in the first sentence. “I am writing to refer Mrs. Chen for specialist endocrinology assessment following newly identified impaired glucose tolerance on routine screening.”

Which criterion it affects: Purpose (Criterion 1)

Pattern 2: Copying the Case Notes Instead of Selecting from Them

What it looks like: A 280+ word letter that includes the patient’s childhood diagnoses, all medications (not just the relevant ones), social history irrelevant to the reader, and the full management plan when only part of it matters.

The fix: Before writing, ask of each piece of case note information: “Does the reader of this specific letter need this to make a clinical decision?” If not, omit it.

Which criterion it affects: Content (Criterion 2), Conciseness & Clarity (Criterion 3)

Pattern 3: Repeating Information Across Paragraphs

What it looks like: The diagnosis appears in the opening paragraph, then again in the history paragraph, then again in the closing. Each paragraph is correct in isolation; together, they fail the conciseness criterion.

The fix: Each piece of information appears exactly once. If you mentioned the diagnosis in the purpose statement, do not repeat it in the history section.

Which criterion it affects: Conciseness and Clarity (Criterion 3)

Pattern 4: Wrong Register — Too Casual or Too Formal

What it looks like (too casual): “The patient is getting better and should be fine soon.”

What it looks like (too formal): “It is with great respect that I humbly request your esteemed attention to the case of the aforementioned patient.”

Neither sounds like genuine professional clinical correspondence.

The fix: Write as a clinician would to a colleague. Professional, specific, direct. See Genre and Style in OET writing →

Which criterion it affects: Genre and Style (Criterion 4)

Pattern 5: Missing or Vague Closing

What it looks like: “I hope this letter has been helpful.” / “Thank you for your time.”

The reader does not know what they are expected to do. This is not a professional closing — it is a social courtesy.

The fix: The closing paragraph must contain a specific request. “I would be grateful if you could arrange an urgent outpatient review at your earliest convenience.” or “Please do not hesitate to contact me should you require any further information.”

Which criterion it affects: Purpose (Criterion 1), Organisation & Layout (Criterion 5)

Retake Preparation Plans by Timeline

8-Week Plan (Intensive Retake)

Best for: Candidates with an exam booked in 8 weeks who have received enhanced feedback and know their weak criteria.

Recommended pack: 8-letter Mastery Pack — gives a teacher enough letters to see patterns across multiple submissions, not just one.

12-Week Plan (Standard Retake)

Best for: Candidates with more time, or those at B2 level who need to work on both language and content selection skills simultaneously.

Total letters: 18–22. Recommended: 10-letter Mega Pack + additional letters.

The Single Biggest Mistake Retake Candidates Make

Most candidates who fail OET Writing practise regularly before their first attempt. They write letters. They check their grammar. They feel like they are preparing.

They retake and fail again.

The reason is almost always the same: they are practising without criterion-referenced feedback. They cannot see which of the 6 criteria they are meeting and which they are not. They improve their weaknesses accidentally, or not at all.

The difference between candidates who fail repeatedly and candidates who pass on their retake is not effort. It is feedback quality.

How to Choose Your Pack Size for a Retake

Frequently Asked Questions

How soon can I retake OET Writing? At any available test session. No mandatory waiting period. Check your registration body’s rules on combining results from multiple sittings.

Can I retake just the OET writing sub-test? Yes. You retake only the sub-tests you have not yet passed.

How long should I prepare before retaking? Most candidates need 8–12 weeks of structured preparation with regular expert feedback — not just more self-study.

Why did I fail despite good grammar? OET assesses 6 criteria. Most failures are in criteria 1–3: Task Fulfilment, Content Appropriateness, and Conciseness. Grammar (Criterion 6) is rarely the primary failure point.

Failing once does not predict the outcome of a retake. What predicts the outcome is whether you understand what changed — and whether your preparation addresses it specifically.
