OET Writing for Pharmacists: What Examiners Look For in 2026

OET Writing for pharmacists is a growing cohort — and one that presents a distinct set of challenges not shared by nursing or physiotherapy candidates. Pharmacists write clinically complex letters centred on medication management, and the temptation to over-explain pharmacological rationale is one of the most consistent errors that costs Content and Conciseness marks.

This guide covers the letter types pharmacists encounter in OET Writing, the scope-of-practice boundaries that affect Genre & Style, the most common content errors, and a full annotated sample letter.

OET Writing Score Requirements for Pharmacists

Grade B is the universal standard for pharmacist registration in English-speaking countries:

Grade B in Writing means a converted score of 350–440 on the 0–500 scale. There is no C+ exception for pharmacy — Grade B is the minimum everywhere.

What Pharmacist OET Letters Typically Involve

OET Writing tasks for pharmacists cluster around several clinical scenarios:

Each of these letter types requires a different emphasis in the Content criterion. A letter to a GP about an ADR should lead with the clinical concern — not a pharmacokinetic explanation of the drug. A discharge medication letter should prioritise changes from prior regimen, not re-list every medication the patient has ever taken.

The 6 Criteria — Pharmacist-Specific Commentary

Scope of Practice: The Pharmacist Boundary in OET Writing

This is where most pharmacist candidates lose Genre & Style marks. Pharmacists are not prescribers (in standard practice). They flag, recommend, and request review — they do not direct clinical decisions.

The difference is not subtle — it’s the difference between directing a prescriber and informing one. Examiners are trained to identify this distinction under Genre & Style.

Content Criterion: What to Include and What to Leave Out

The Content criterion (/7) is where pharmacists most commonly lose marks — not through omission, but through inclusion of irrelevant pharmacological detail.

For an ADR letter to a GP, required content includes:

• The suspected drug (name and dose)
• Nature and onset of the adverse reaction
• Patient’s current clinical status related to the reaction
• Any action already taken (e.g., drug withheld, patient advised)
• The specific clinical request (e.g., review, alternative agent consideration)
• Relevant background (only if it affects the clinical decision — e.g., known allergy history, renal impairment)

Distractor content that costs marks (for an ADR letter):

• Mechanism of action of the offending drug (“Lisinopril works by inhibiting the angiotensin-converting enzyme…”)
• Extended pharmacokinetic detail
• Unrelated medical history
• Lengthy medication list that is not relevant to the ADR
• Background on the drug class when the recipient (a prescribing GP) already knows it

Organisation: What Leads a Pharmacist Letter

As with all OET letter types, pharmacist letters must be organised thematically by clinical priority — not chronologically.

The most common Organisation error for pharmacists: beginning the letter with when the patient started taking the medication, then working chronologically through the medication history, eventually arriving at the current concern.

Chronological (incorrect):

Mrs. Patel was prescribed lisinopril 10mg in 2019 for hypertension. In 2021, her dose was increased to 20mg. She has been taking this medication without incident until last week when she presented to the pharmacy with a persistent cough.

Thematic (correct — clinical concern leads):

I am writing to request urgent review of Mrs. Patel’s lisinopril, which I believe may be the cause of a persistent dry cough she has reported over the past two weeks. She has been on lisinopril 20mg for hypertension since 2021.

The thematic version states the clinical concern immediately, then provides the relevant background. The examiner understands the purpose in the first sentence.

Sample Letter: Pharmacist ADR Referral to GP

Scenario: You are a community pharmacist. Mrs. Grace Okafor, 58F, presents to your pharmacy with a persistent dry cough of 3 weeks duration. She is currently prescribed lisinopril 10mg OD for hypertension (commenced 6 weeks ago) and metformin 500mg BD for Type 2 diabetes. She has no known drug allergies. Her BP readings at the pharmacy today: 138/86 mmHg. You suspect a lisinopril-induced cough and are writing to her GP, Dr. Murphy, to request a medication review.

Dear Dr. Murphy,

Re: Mrs. Grace Okafor, DOB 22/09/1967

I am writing to request a medication review for Mrs. Okafor, who has presented to our pharmacy with a persistent dry cough that I believe may be attributable to her recently commenced lisinopril therapy. [Purpose — clinical concern named, specific request made, suspected cause identified]

Mrs. Okafor reports a dry, non-productive cough that developed approximately two weeks after commencing lisinopril 10mg once daily, six weeks ago. The cough is persistent and has not responded to over-the-counter remedies. There is no associated dyspnoea, wheeze, or fever. Her blood pressure measured at the pharmacy today was 138/86 mmHg. [Current status — nature and timeline of ADR, current BP as clinically relevant finding]

She continues her metformin 500mg twice daily for Type 2 diabetes without reported side effects. She has no known drug allergies and no prior history of cough or respiratory conditions. [Relevant background — only what is clinically pertinent to the review decision]

Given the temporal relationship between lisinopril commencement and symptom onset, I would appreciate your review with consideration of an alternative antihypertensive agent if clinically appropriate. [Closing request — within pharmacist scope, specific but not directive]

Please do not hesitate to contact me should you require any further information.

Yours sincerely, David Nwosu, MPharm Greenfield Community Pharmacy

Word count: 198 words. This letter demonstrates:

• Purpose in sentence one with the clinical concern and suspected causative drug named
• Current clinical status (cough characteristics, BP) leading the body before background
• Background limited to directly relevant information (metformin, no allergy history, no respiratory history)
• No pharmacological mechanism explanation — the GP knows how ACE inhibitors work
• Closing request that recommends review without directing prescribing decisions (scope maintained)
• Passive voice used appropriately for medication management context

Before and After: Content Over-Explanation Error

Here is the same clinical scenario, with the pharmacology over-explanation error that commonly appears in pharmacist OET drafts:

❌ With distractor content:

Lisinopril is an ACE inhibitor that works by blocking the angiotensin-converting enzyme, which prevents the conversion of angiotensin I to angiotensin II. This leads to vasodilation and reduced blood pressure. However, a known side effect of ACE inhibitors is bradykinin accumulation, which can cause a persistent dry cough in approximately 10–15% of patients. This is a class effect of all ACE inhibitors. Mrs. Okafor has been taking lisinopril 10mg for six weeks and has developed a dry cough…

Problems: This paragraph is a pharmacology lecture. The GP prescribing lisinopril knows its mechanism of action and the class-effect cough rate. This content adds approximately 60 words of distractor content — which both pushes the letter over 200 words and signals poor reader calibration. Content marks are lost; Conciseness marks are lost.

✅ Corrected:

Mrs. Okafor reports a persistent dry cough that developed two weeks after commencing lisinopril 10mg, six weeks ago.

Eight words instead of sixty-five. Same clinical information relevant to the GP’s decision. The mechanism is implied by naming the drug — the GP does not need it spelled out.

Practise With Pharmacist-Specific OET Tasks

The Content criterion for pharmacist OET letters requires a very specific reader-calibration skill — understanding what a GP or specialist already knows versus what they need from you. This is difficult to self-assess without criterion-specific feedback that tells you whether your content selection was appropriate for the reader.
