Quick answer
Choose a formal letter only when it is one of the options in your task and it serves the stated audience and purpose. The goal is not to reproduce a memorized template. Make the relationship between reader, purpose, content and form visible throughout the response.
When a formal letter makes sense
An official, organization or professional contact you do not know personally.
Request, complain, apply or inform in a way that a busy recipient can act on.
Start by writing a one-line communication brief: who is reading or listening, what they need from you and what should happen after they receive the text. If another allowed form would make that job clearer, choose the other form.
A practical structure, not a memorized template
A suitable salutation, a first paragraph that states why you are writing, body paragraphs that group facts and reasons, a polite statement of the response you expect, and a formal close.
Conventions should make the communication easier to understand. They are not decoration. If a heading, greeting, direct address or sign-off does not help the reader understand the relationship and purpose, do not add it simply because an online template told you to.
- Audience is obvious
- Purpose appears early
- Required content is covered
- The form remains consistent
- The ending completes the communication job

Original opening example
For an original public library practice task, one possible opening is: “I am writing on behalf of the students of Northfield School to ask the council to reconsider the decision to close the public library on weekday evenings.”
Do not memorize that sentence. Instead, explain why it suits this audience and purpose, then rewrite the opening for a different context. If changing the recipient barely changes your language, you may be writing a generic essay rather than controlling register and form.
Original Paper 1-style practice prompt
Your town plans to shorten the opening hours of the public library. Write a formal letter to the local council explaining how students use the library and asking for the decision to be reviewed.
This is an original Nektar practice prompt, not an official IB examination question. Plan the audience, purpose and required details before drafting. After writing, cover the prompt and ask another reader to infer who the text is for and what response you wanted.

Common mistakes to catch in revision
A useful revision asks whether the form improves communication, not whether it contains a checklist of surface features. The most important problems usually come from a mismatch between the task and the writing.
- Opening with background and reaching the purpose only at the end
- Mixing formal address with casual phrases or contractions
- Complaining without stating what response you want
