Writing for purpose, audience and form (the PAF triangle)

Both Edexcel writing tasks (Paper 1 imaginative; Paper 2 transactional) reward writing that demonstrably knows who it's addressing, why it exists and what shape it takes. Strong students plan PAF before writing a single sentence.

Purpose

Six core purposes: describe, narrate, explain, argue, persuade, instruct. Most Edexcel transactional tasks involve argue or persuade (often both: argue with persuasive features). Imaginative tasks usually combine describe and narrate.

Audience

Specifies register, vocabulary, formality, sentence length, references. A letter to a head teacher uses formal address ("Dear Mr Patel"), more elaborate sentences and avoids slang. A speech to peers uses inclusive pronouns ("we"), rhetorical questions and shorter, punchier sentences.

Form

Each form has conventions:

• Letter: address, salutation, sign-off, paragraphs.
• Speech: opening hook, direct address, rhetorical devices, memorable close.
• Article: headline, standfirst-like opening, sub-headings (optional), strong final image.
• Report: factual register, cited evidence, neutral tone, clear conclusion.
• Blog: informal but coherent, personal voice, web conventions.
• Diary entry: dated, first person, reflective, intimate.

The five-minute plan

Before writing:

1. Underline purpose words in the prompt ("argue", "explain").
2. Name the audience and what register they expect.
3. List form conventions you'll meet.
4. Sketch four paragraphs (intro / body 1 / body 2 / strong close).
5. Plan an opening hook AND a final image / call to action.

This 5 minutes is worth 5–10 marks across AO5/AO6.

Coherence — the connector test

Read each paragraph back: does it begin with a sentence that signals how this paragraph connects to the last? Connectors at the start of paragraphs are how Edexcel measures structural coherence.

Examples: Beyond this, however, …; A second concern is …; Of course, the picture is more complicated when we consider …

Common slips

1. Form drift: starting in letter form, drifting into article style mid-way.
2. Wrong register for audience: "Hey guys!" in a letter to the head teacher.
3. Convention misses: forgetting a sign-off; no headline on an article.
4. Argument with no evidence/example: "We should ban this. It's bad. End of." Argue with reasons and concrete examples.

PAF is what separates Level 4 writing (matched to task) from Level 3 (technically clean but generic).
