Vu said that she gets one question all the time: What are the legal standards? There is no legal standard, but there are guidelines out there: The Web Content Accessibility Guidelines (WCAG), version 2.0, with 3 levels of conformity: A, AA, AAA. They were put out by W3C. Companies can use those guidelines. The Justice Dept. uses the A and AA levels.
All public-facing websites should evaluate and consider compliance with ADA laws related to their industry. That is, your website should aim to be accessible to users with a disability. Failure to comply with this requirement can lead to potential legal issues and challenges, particularly in some industries. Fortunately for WordPress site owners, there are at least a dozen plug-ins specially designed to help you achieve greater measures of ADA compliance with minimal costs and work involved. The following are five options to consider to make your WordPress website ADA compliant.

@Rick, I didn't specifically look at doctype, but Steve Faulkner did in his original article (see the link at the top of this post). He found that 101 of the 130 pages containing role="main" (78%) used the HTML5 doctype, which of course leaves 22% that didn't. I do recommend using ARIA even if using an earlier doctype. Validation is important, but if validation and accessibility conflict, I think most would agree accessibility should trump validation. Assistive technologies that support ARIA landmarks do so regardless of doctype, and otherwise the presence of these role attributes has no ill effects in any user agent.

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.
Use the plugin, follow its instruction, and resolve the compliance issues identified. You’ll find that using the plugin will save you an incredible amount of time as you maintain your site’s compliance on a month-to-month basis. The best part, it identifies the compliance issues and tells you exactly which code elements are out of compliance and why! Our average customer is reporting a 10x-20x time savings over manually identifying and fixing these problems. In extreme cases more than 30x time savings has been reported! Using the plugin alone does not guarantee compliance. Some parts of accessibility can’t be automatically scanned and must be manually audited but we also provide independent 3rd-party audits and certifications of compliance. The Accessibility Suite Pro Plugin for WordPress makes this process profoundly easier.
WordPress themes designed with accessibility in mind tend to be easier to use and clearer to navigate than their contemporaries. While you may have specific goals in mind like ADA compliance or WCAG 2.0 standards to pass, rest assured that you won’t have to sacrifice on design quality. You’ll likely find a theme with a higher standard of design by searching for templates with these requirements.

Automated testing is the first step toward determining if your website is accessible to people with disabilities, including those using assistive technologies like screen readers, screen magnifiers, switch controls, and others. The free testing tools on this website will give you an idea of whether your website is compliant with laws like Section 508, the Americans with Disabilities Act (ADA), and the 21st Century Communications and Video Accessibility Act. If you find you have many violations, Level Access has experts that can help you reduce your legal risk.
For most people, the Americans with Disabilities Act (ADA) conjures up pictures of physical accommodations such as wheelchair ramps near building entrances, handicapped parking spaces, and the use of braille writing on signs and placards. These measures have been tremendously valuable in helping the 56.7 million Americans with a disability function and thrive within society.
...the full and equal enjoyment of the goods, services, facilities, or accommodations of any place of "public accommodation" by any person who owns, leases, or operates a place of public accommodation. Public accommodations include most places of lodging (such as inns and hotels), recreation, transportation, education, and dining, along with stores, care providers, and places of public displays.
