OET Writing Paragraphing: Why Three Paragraphs Is Not a Rule

“Use three paragraphs” is advice you will hear in OET preparation courses, and it is not wrong, as a starting point. The problem is that candidates treat it as a formula rather than a principle. When the task is complex, three paragraphs forces unrelated clinical information into the same section, which is exactly what loses Organisation and Layout marks.

This post explains what examiners actually check under Organisation and Layout, how to decide how many paragraphs a task needs, and the specific grouping errors that cost marks.

What Organisation and Layout assesses

The Organisation and Layout criterion is scored 0–7. At Band 7, paragraphing is “appropriate, logical and clear” with key information highlighted and the document well laid out. At Band 5, the structure is mostly correct with occasional lapses. At Band 3, the organisation creates strain for the reader and key information may not be highlighted.

The examiner asks: can I find what I need as a reader, and does the letter flow in a sequence that makes clinical sense?

Two separate things are being scored: paragraphing (how information is grouped within the body) and layout (the structural elements that frame the letter).

Layout: what belongs before the first paragraph

Layout marks are lost when structural conventions are missing or misplaced. A professional letter includes:

• Date (top right or top left, depending on convention)
• Recipient name and professional designation
• Recipient organisation or clinic
• Subject line: “Re: [Patient name], DOB/ID, [brief task descriptor]”
• Salutation: “Dear Dr. [surname],” not “Dear Doctor,” and not “To Whom It May Concern”
• Closing convention: “Yours sincerely,” (for named recipient) or “Yours faithfully,” (unnamed)

Candidates who start writing body content immediately without the structural frame lose layout marks before they have written a clinical sentence.

Paragraphing: the one-idea principle

Each paragraph should contain one clinical theme. When two different themes appear in the same paragraph, the reader has to search for each within a block of mixed content. That is what the examiner means by “strain.”

The most useful clinical themes to separate:

A simple referral for a straightforward condition may need only three paragraphs: opening purpose + relevant background, clinical picture and investigations, referral request. A discharge letter for a patient with multiple active problems may need five: purpose, relevant history, current presentation, the management plan on discharge, and follow-up arrangements.

The case note order trap

Case notes are usually structured chronologically or by system. Following their order produces a letter that reflects how the notes are written, not how the reader needs information presented. Examiners have a specific descriptor for this: “heavy reliance on case note structure” appears at Band 1 for Organisation and Layout.

The reader’s sequence is different from the case note sequence. Start with what this reader needs to know first to understand the purpose. Then add the history that contextualises the current situation. Then present the clinical picture. Then the plan.

This reordering requires deciding before you write, during the reading stage, what sequence serves the recipient. The full approach is described in the case notes reading guide.

Where to put the management plan

The management plan is almost always key information. It is what the receiving clinician needs to act on. Burying it inside a history paragraph because it appeared at the bottom of the case notes is one of the most consistent reasons Organisation and Layout drops below Band 5.

Put the management plan in its own final body paragraph, before the closing convention. If follow-up arrangements are separate from the immediate management, give each its own sentence or its own short paragraph depending on complexity.

A letter that ends with “The patient was discharged and has been given a follow-up appointment” buried inside a paragraph about social history has technically included the information. An examiner still penalises it because it was not highlighted. The reader had to find it rather than having it presented clearly.

Checking your own structure

After you have drafted the body of the letter, ask three questions:

1. Does each paragraph contain one clinical theme, or have two themes been merged?
2. Can the recipient locate the management plan or referral request without reading every paragraph?
3. Does the order of paragraphs reflect the recipient’s information needs, or the order of the case notes?

These three questions catch the majority of Organisation and Layout errors before they reach the examiner. For the complete scoring picture, the OET writing criteria hub has the full descriptor tables for all six criteria.
