To meet WCAG 2.1 to level AA you must be able to answer YES or Not Applicable to all of the following questions.

Answering NO means that you are not meeting WCAG and your content will have barriers that will prevent some users, especially disabled users and older people from accessing it.


  • Do all images have an appropriate text equivalent? Is essential visual information also available as text?
  • Do all audio files have a transcript? Is essential audio information available as text?
  • Do all videos have captions that are synchronised with the audio?
  • Does video that includes important visual information have an audio description?
  • Is all content structure that is communicated visually available to assistive technologies?
  • If styling is removed is the content in a logical order?
  • Have you avoided using visual characteristics to communicate information?
  • Have you avoided using colour as the only way to convey some information?
  • Can users stop audio that auto plays?
  • Does all text have sufficient contrast against the background colour?
  • Is the content fully usable when text is enlarged up to 200%?
  • Have you avoided using images of text?
  • Can users flip the content horizontally and vertically?
  • Have you added HTML autocomplete tokens to any forms collecting information about the user?
  • Does the page content resize to a single column with no horizontal and vertical scrolling?
  • Do all important graphical objects, interface components, and states have a colour contrast of 3:1?
  • Can line height, spacing between paragraphs and letter and word spacing be changed without breaking anything?
  • Where extra content is shown or hidden on focus, can it be dismissed, interacted with (and not disappear when the user moves to it) and will stay visible until dismissed by the user?


  • Can all menus, links, buttons, and other controls be operated by keyboard?
  • Do pages that have time limits include mechanisms for adjusting those limits?
  • Can any content that moves or auto updates be stopped?
  • Have you avoided using content that flashes or flickers?
  • Can blocks of links and other interactive elements be bypassed by keyboard users?
  • Does each page have a unique title that indicates its purpose and context?

  • Do you have shortcuts triggered by only one letter or character? If so can they be turned off or remapped by the user?
  • Does some of your site functionality need several fingers or complex gestures to operate it? If so, can the same functionality be used with just one finger, single taps or clicks?
  • Does some of your site functionality work using a single point (e.g fingertip)? If so, have you ensured it does not get triggered the moment it is touched?
  • On forms and other components is the accessible name or label the same as any on-screen text?

  • Do forms provide helpful, understandable error and verification messages?


  • Is the web page coded using valid HTML?
