ADA Section 508 Level AA Accessibility Standards

Are you looking for the actual (Level AA) ADA Section 508 Accessibility Standards?

We will show you exactly what the Level AA Section 508 Accessibility Standards are on this page.

When we got our first ADA Section 508 compliance job for a client, we were not 100% certain on what it would take to bring this website into compliance. This is when our journey down the rabbit hole began. It seemed as much as they wanted us to use these recommendations for people with disabilities. They did not make it very easy for web developers like us to find this information. Then, what information we did find was like reading tax code from the IRS.

There are 3 levels of the ADA Section 508 Accessibility Standards:

  • Level A: This is the lowest possible set of standards for ADA Section 508 Accessibility. Although this will make you mostly compliant. It does not, in my opinion, elevate the user experience for the person who needs it most.
  • Level AA: This set of standards is the level that you want to achieve to make sure you are completely compliant. This set of standards makes a huge difference in the user experience for the end user.
  • Level AAA: This is the highest set of ADA Section 508 Accessibility Standards. If you can implement the Level AAA standards in your website or software. Then you will be exceeding the requirements and have created an amazing user experience for people with disabilities.

Level AAA is the level you want to shoot for, but by accepting nothing less than Level AA you will create a 100% compliant website and great user experience. You will create a true ADA section 508 Compliant website.

ADA Section 508 Accessibility Standards in 7 simple steps.

We understand how difficult it is to understand these ADA Section 508 Standards. This is why we try to sum up ADA Section 508 Compliance in 7 steps.

  1. Make sure you have Alternative Text for all of your non-text media.
  2. You must make sure that all videos you upload include a manuscript of that audio. You have to also include an audio description for non-audio animations.
  3. Make sure the color of any given content is not the only indicator of what it is.
  4. The whole website or software you create must be able to be navigated with just the Tab button on the keyboard.
  5. Make sure there are no time limits on your site for any reason.
  6. Always include a skip navigation link or something equivalent, so the user can bypass repetitive content.
  7. If there is an input error by the user, it must be identified and described in the text to the user.

If you can follow these 7 simple steps your website or software will almost be totally ADA Section 508 Compliant. I hope this has helped you.
