-        <p>Write out an acronym in full the first time you use it on a new page or screen, unless it is well known to your users, like UK, US or NHS. Research has found that some users struggle to remember the meaning of an acronym they saw on a previous screen. For example, write 'biometric residence permit (BRP)' on each screen of your service at first mention and use 'BRP' if it appears again on the same screen. If available, use a tooltip like <A href="https://www.gov.uk/guidance/how-to-publish-on-gov-uk/markdown#acronyms">acronym Markdown</A> to make the acronym appear in full as hover text.

For example, the first time ‘immigration health surcharge (IHS)’ appears on each screen of your service, write it out. On subsequent mentions on the same screen, use ‘IHS’.
