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.
When choosing an aid or service, title II entities are required to give primary consideration to the choice of aid or service requested by the person who has a communication disability. The state or local government must honor the person’s choice, unless it can demonstrate that another equally effective means of communication is available, or that the use of the means chosen would result in a fundamental alteration or in an undue burden (see limitations below). If the choice expressed by the person with a disability would result in an undue burden or a fundamental alteration, the public entity still has an obligation to provide an alternative aid or service that provides effective communication if one is available.
Is your website accessible to ALL users? The Americans with Disabilities Act (ADA) of 1990 prohibits discrimination based on disability. Legal precedent has now evolved to include new forms of technology and communication under the act – like websites. ADA compliance for websites will be federally regulated come 2018! Find out more about the new ruling and what you could be doing to prep your website for these accessibility requirements.

Higher search engine rankings is another potential benefit of voluntary compliance with the ADA. During your migration, an ADA specialist will audit it to detect and address usability challenges. These difficulties include the inability for search engine spiders to index your site easily. When you address such issues, your site will rank highly in search engines.
Web developers need to keep this in mind when creating websites. The best screen readers use naturalized voices and alter tone and inflection based on HTML tags, so choose layout elements carefully. It is also important to keep in mind that navigation is significantly slower when using a screen reader than it is for sighted people. Sighted people don't have to wait for the reader to get to the link we want- we spot links quickly and are able to navigate to our sought items, often without having to do any reading at all. Minimizing graphics also helps shorten reading times and speed navigation for disabled users.
A language picker at the top of the page. When users select a new language, the page is reloaded with all text translated. The lang attribute on the element also changes to reflect the new language, so screen readers will pronounce the text correctly. This is a very cool feature, and makes the site accessible to millions of people who would otherwise be excluded due to language. However, it's a little buggy. Selecting some of the languages (e.g., " Slovenčina") does not result in translated text on the home page, but does result in a changed lang attribute, so screen readers that support the selected language will pronounce the English text using the new language's speech engine, which is not likely to be intelligible.
This is particularly important when working for a government agency or government contractor, as these organizations must follow web accessibility guidelines under Section 508 of the Workforce Rehabilitation Act of 1973. Although ADA and Section 508 compliance are different, the published checklist for Section 508 compliance offers insight into ways to make websites accessible for people with disabilities, and thereby work toward ADA compliance.
Accessible design benefits all users and creates market opportunity, Reha said. She continued: “Access to information online is everywhere, so it’s easy to take for granted that it’s available to everyone, but it’s not. Such access is incredibly important for people with disabilities because it lets them become independent and improves their quality of life.”
The landscape of disabled access litigation related to online services has significantly changed and expanded over the past decade. Initially, the internet was an area of little concern as courts uniformly held that the ADA applied to "brick and mortar" facilities, not to cyberspace. This has changed and online accessibility is presently, and will continue to be, an area of significant investigation and litigation.
Hi Ashley, Thanks for the feedback. However, I respectfully disagree about JAWS. There was a time many years and versions ago when screen readers didn't support id attributes as targets, but that's no longer true. I just tested my site with JAWS 14 in both IE9 and Firefox 17. In both browsers JAWS identifies the link as "Same page link Skip to main content", then if I click on that link using the left mouse button I jump directly to the "main region", and a couple of down arrows later I'm on the main heading. I actually wrote an earlier blog post about this very topic.
Many deaf-blind individuals use support service providers (SSPs) to assist them in accessing the world around them. SSPs are not “aids and services” under the ADA. However, they provide mobility, orientation, and informal communication services for deaf-blind individuals and are a critically important link enabling them to independently access the community at large.
You can test specific themes for compliance with these guidelines using a tool such as the WAVE Web Accessibility tool.  For sites that require 100% compliance, we recommend testing your theme of choice using the demo page for the theme, for example Twenty Fourteen. We also recommend using Header Text (displaying the Site Title), rather than a Header Image, as some themes will not provide AltText and therefore generate an error in the accessibility tool when a Header Image is set.
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.

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!

When you insert an image into a post or page, consider providing a rich description for the caption that will improve the reading experience for everyone, but especially folks who can’t see the image. Be creative. Instead of “My son on his swing,” try “My son is playing on his favorite swing. His face is filled with pure joy on a beautiful Spring day. Perfection.” The goal here is to convey the feeling of the image.
