Success Criterion 3.2.4 - Level AA

Consistent Identification

Ensure icons always have the same function. For example, only use a magnifying glass icon to search, and not to enlarge. This makes it clear to users which function they can expect from this icon.


  • Consistent use of icons makes it easier for everyone to learn what function each icon has

  • People with learning disabilities can use the app more easily if icons are used in the same ways.


“Do icons have the same function everywhere?”

This can be tested without assistive technologies.

Note: this success criterion is exempt for apps in EN 301 549 and Section 508.
