You probably won't have to check your site with all of the available evaluation tools out there, but it is a good idea to do so for the most common web browsers. Just as accessibility software makes it easier for people with disabilities to navigate the Internet, these tools make it easier for developers to ensure accessibility from the start. When you think you've mastered it, go back through the Section 508 compliance checklist to ensure you've met every goal.
In short, the ADA is meant to protect disabled individuals as they go about their daily lives. These regulations ensure that people with disabilities are not denied entry into the above places or denied services by a company due to their disability. It is important to note that these regulations are now applicable to services that are provided online or through other digital formats. For example, if a company accepts job applications online, then it must ensure that a person with a disability can also apply for the job online. In other words, it is illegal to have barriers on the website that would keep the disabled individual from successfully completing their application. Fortunately, the ADA guidelines help to remove barriers and ensure that the Internet remains a space that people of all backgrounds and disabilities can use.

Through the Americans with Disabilities Act (ADA), our nation committed itself to eliminating discrimination against people with disabilities. The U.S. Department of Justice’s (DOJ) Civil Rights Division is proud to play a critical role in enforcing the ADA, working towards a future in which all the doors are open to equality of opportunity, full participation, independent living, integration and economic self-sufficiency for persons with disabilities.
The World Wide Web Consortium (W3C) established the main international standards and accessibility for the World Wide Web. The WCAG is created by the W3C to provide a standard for web content accessibility that can be shared around the world. The WCAG is meant to accompany organizations as a sort of blueprint on how to make their websites ADA compliant.
Every year numerous lawsuits are taken against businesses that fail to follow the ADA’s proposed requirements for web accessibility. This failure occurs because organizations, including state and local government entities, fail to read the ADA Best Practices Tool Kit.8 They also do not follow the most up to date version of the WCAG.9 These two failures are not only detrimental to people with disabilities who want to effectively browse the web, but they are also inexcusable in today’s digitally driven world.
Hey Casey, this is one of the areas where things get a little weird because the W3 doesn’t actually have any say over the ADA guidelines, it is more than the ADA guidelines adopted the WCAG 2.0 guidelines as just that, a guideline to help. As far as I know, the tool you’ve linked to hasn’t been used in any judgements I’m aware of. Usually when it comes down to making a decision on if something is/isn’t compliant they have people use the actual PAWS tools and show what elements do/don’t work as intended or are otherwise inaccessible. Hope this helps!
Talk to your web designer about other techniques that will make your site more user-friendly for people with disabilities. Worried that’s not in your budget? Consider the fact that DOJ fines start at $75,000. And it's still yet to be determined if a non-compliant website is liable for one fine or will be charge per page for each violation. As the recent lawsuits illustrate, though, settlements quickly add up into the millions.
Finally, WA11Y is another top ADA compliance plug-in to consider. A toolbox of resources to help you meet most ADA compliance needs, the plug-in packs multiple accessibility tools, each with a unique purpose. Tota11y, the first tool in the box, for instance, annotates all elements of your web pages and identifies any accessibility issues. Another tool in the box, WAVE, performs a detailed accessibility analysis of each page and provides printable reports. Then, you have FILTERS which is used to modify data within Wa11y.
The Americans with Disabilities Act (ADA) was first passed in 1990. Twenty years later, the US Department of Justice released an update called the 2010 ADA Standards for Accessible Design. These standards cover the design of physical spaces and have been interpreted to include web locations as well, so it can be difficult for the would-be accessible website designer to use them.
