WCAG 2.0 Compliance comes in three levels (less compliant to more compliant, or easiest to hardest):

●A

● AA

● AAA

Itʼs important to note that WCAG AAA compliance relates 100% with Section 508, which severely impacts design, performance, look and feel of a website. The Department of Justice (DOJ) has admitted that 508 compliance (AAA) is not practical, which is why A and AA are the acceptable standards.

Level A Compliance

  • Level A Compliance includes basic guidelines that enhance website accessibility:
  • Media players should contain a link to site where the software can be downloaded.
  • “Skip navigation” functionality should allow users to access content easily.
  • Users should be notified of any invalid information they enter.
  • Photos should include alternative text readable by screen reader software.
  • Video content should have text captions.
  • Video/audio content should have text transcripts or descriptions.
  • Look of website should not rely only on color.
  • Page titles should thoroughly describe the page content.
  • Links should be clearly named.
  • Automatically played audio can be stopped immediately.
  • Use “strong” and “em” tags instead of “b” and “i” tags.
  • No empty links or heading tags.
  • Headings should appear in a logical order.
  • Users should be notified of any time limits.
  • All pages must have a language code in header.
  • Forms contain labels and legends that are readable by screen reader software.
  • Content that automatically scrolls, flashes, or blinks can be disabled.
  • Website should be free of strobe effects or rapidly flashing colors or animations.
  • Interactive elements shouldnʼt affect readability or layout of webpage.
  • Website can be navigated using the keyboard.
  • Keyboard focus shouldnʼt lock on to any specific page element.
  • Website should pass W3C HTML validation without any major errors.

    Level AA Compliance

    Level AA is more advanced compared to Level A and is the second level required for full ADA compliance:

  • Website pages can be accessed multiple ways.
  • Contrast ratio between readable and background elements should be at least 4.5t1.
  • Live video and audio streaming should have captions.
  • Photos do not replace any function that can be achieved through text.
  • When resized to 200%, text should maintain form and not affect the page layout.
  • Keyboard focus should be clear and visible always.
  • Menus and buttons should have consistent order and presentation throughout the site.
  • Website should be free of underlined text that does not contain a link.
  • Use of repetitious links on the same page should be minimized or eliminated.
  • Suggestions should be provided whenever a user faces input errors.
  • When asking users for sensitive data, error prevention techniques should be in place.
  • Sites using multiple languages should identifiy the languages in code for each page.
