What this dot point is asking
A third kind of Unit 2 writing is exposition: writing that explains or informs. To reach the top band you organise information clearly and logically for a purpose and audience (AO5), and write accurately with varied vocabulary and sentences (AO6). Half the marks are for communication and organisation, half for technical accuracy.
Exposition informs, it does not argue
The purpose of exposition is to make something clear, not to win a case or tell a story.
Plan a clear structure
Clarity comes from structure. An expository piece reads well when the reader can follow its organisation.
Develop each point with explanation and example
A point asserted is not a point explained. Exposition develops each idea.
State the point (loyalty matters in a friend), explain why (it means they stay through difficulty), and illustrate it (a friend who stood by you when others did not). The explanation and example are what make the writing informative.
Match tone to audience
Exposition still has an audience, and the tone should fit it. A school magazine piece can be warm and direct; an informative article for a general reader is clearer and more neutral; a report is more formal still. The informing purpose stays the same, but the register shifts to suit who is reading. Matching the tone to the audience shows the control over communication that AO5 rewards, and it stops the writing feeling generic.
How the expository task appears on the paper
Exposition can appear as a Unit 2 writing option, asking you to explain or inform on a topic for a stated audience and form, such as a magazine piece or an informative article. The examiners reward clarity and organisation above all: a piece the reader can follow easily, with a clear introduction, developed and illustrated points, and a rounding-off conclusion. The marks split evenly between communication and organisation and technical accuracy, so structure and proofreading each matter as much as the content. The two failures that most often pull these answers down are a shapeless ramble with no clear structure, and a drift into persuasion, arguing a case instead of explaining, so keep checking that you are informing the reader rather than trying to win them over.

Exposition explains or informs clearly and logically (AO5), written accurately (AO6). Half the marks are communication and organisation, half accuracy.
Plan a clear structure: an introduction that frames the topic, two or three developed points (loyalty, honesty, support) each with explanation and example, and a conclusion. Match the tone to a school magazine audience, use linking words, and proofread.
Markers reward clear, organised explanation; weaker answers ramble without structure or drift into a personal anecdote that loses the explaining purpose.
WJEC Unit 220 marksWrite an article informing readers about the benefits of regular exercise.Show worked answer →
This is exposition, so inform the reader clearly and logically (AO5), accurately (AO6). The purpose is to explain, not to persuade or narrate.
Structure it: an introduction, developed points (physical health, mental health, social benefits) each explained with an example, and a conclusion. Use a clear, informative tone for a general reader, signpost with connectives, and vary sentences.
The top band is clear, well-organised and informative; common failures are a shapeless ramble or slipping into a persuasive rant.
