Goal: Introduce the main rules of plain language using the ISO standard.
Plain language is not just about writing “simply.” It’s a structured approach to communication that helps people find, understand, and use the information they need. That means it’s just as much about design and structure as it is about word choice.
The most widely recognised principles of plain language are outlined in the ISO 24495-1:2023 standard and promoted by organisations like the International Plain Language Federation (IPLF). These principles can be grouped into four categories:
- Relevance
Focus only on the information your reader needs. Avoid adding extra details that distract or confuse. Start by asking: what is the reader trying to do with this information?
- Findability
Structure your text so that the reader can quickly locate what they’re looking for. Use headings, bullet points, summaries, and consistent layout. Make navigation obvious.
- Clarity
Use familiar vocabulary and sentence structures. Prefer the active voice (“We will contact you” instead of “You will be contacted”) and explain any necessary technical terms.
- Usability
Make sure the reader can act on the information. This includes using step-by-step instructions, logical order, and clear calls to action (“Fill in this form by 30 June”).
These principles apply to written documents, websites, signage, forms, and more. And they can be tested: by asking users whether they could complete a task using the communication, we can measure the effectiveness of plain language.
Plain language isn’t just a good habit—it’s a professional standard. When done well, it improves transparency, inclusion, and trust.
