Even though automated testing is a great tool any tester can have, there are still some issues that even the most sophisticated testing platforms can’t detect. Automated testing platforms are not able to detect how a screen reader relays the content to the user, how the page navigates using the keyboarding (tabbing through the site), alternative text that is inadequate (automated tests are just checking to make sure you have something in the ALT text field), certain color combinations that fall outside acceptable ratios for contrast, and videos that are uncaptioned or do not contain text transcripts.
“The idea of equal access, equal opportunity has sort of evolved in its application from brick and mortar to eCommerce. At first, many companies were worried about the desktop experience. Now, the concern extends to both smart phones and devices.  Wherever a consumer accesses your content – whether it be directly through the web or an app – you need to be concerned about accessibility.”
(2) In situations not involving an imminent threat, an adult accompanying someone who uses sign language may be relied upon to interpret or facilitate communication when a) the individual requests this, b) the accompanying adult agrees, and c) reliance on the accompanying adult is appropriate under the circumstances. This exception does not apply to minor children.
Title II applies to public transportation provided by public entities through regulations by the U.S. Department of Transportation. It includes the National Railroad Passenger Corporation (Amtrak), along with all other commuter authorities. This section requires the provision of paratransit services by public entities that provide fixed-route services. ADA also sets minimum requirements for space layout in order to facilitate wheelchair securement on public transport.[20]

While Title III of the ADA applies to businesses with more than 15 employees, it is a good idea to be proactive and become compliant. In addition, the general consensus is that any business considered a “public accommodation” should have an ADA compliant website. Given that “public accommodation” definition is subjected to interpretation, it is important for a business to do the right thing and become compliant.

So, without a clear set of accessibility regulations to comply with, how can you tell if your website is compliant? The best measure available is the aforementioned WCAG 2.0 Level AA guidelines. WCAG standards have been the guiding accessibility principle in the European Union and other countries since 1999, with the most recent update taking effect in Spring of 2018. While WCAG is a set of recommended actions rather than enforceable legislation, it forms the backbone of many online accessibility laws around the world and offers a strong model for any American organization striving to provide equal access for all users.
The ADA’s relationship with websites has been a complicated and often confusing story. The ADA does not explicitly address online compliance, even after undergoing several amendments in the far more web-oriented era of 2008. With no specific coverage under the law, it usually falls to the courts to determine how ADA standards apply to websites—or whether they do at all. 
Students with disabilities in public schools (K-12) are covered by Individuals with Disabilities Education Act (IDEA), Title II of the ADA, and Section 504 of the Rehabilitation Act. Students with disabilities in public postsecondary education are covered by Title II and Section 504.  Title III of the ADA applies to private schools (K-12 and post-secondary) that are not operated by religious entities. Private schools that receive federal funding are also covered by Section 504.
The free nationwide telecommunications relay service (TRS), reached by calling 7-1-1, uses communications assistants (also called CAs or relay operators) who serve as intermediaries between people who have hearing or speech disabilities who use a text telephone (TTY) or text messaging and people who use standard voice telephones. The communications assistant tells the telephone user what the other party is typing and types to tell the other party what the telephone user is saying. TRS also provides speech-to-speech transliteration for callers who have speech disabilities.
Shortly before the act was passed, disability rights activists with physical disabilities coalesced in front of the Capitol Building, shed their crutches, wheelchairs, powerchairs and other assistive devices, and immediately proceeded to crawl and pull their bodies up all 100 of the Capitol's front steps, without warning.[38] As the activists did so, many of them chanted "ADA now", and "Vote, Now". Some activists who remained at the bottom of the steps held signs and yelled words of encouragement at the "Capitol Crawlers". Jennifer Keelan, a second grader with cerebral palsy, was videotaped as she pulled herself up the steps, using mostly her hands and arms, saying "I'll take all night if I have to." This direct action is reported to have "inconvenienced" several senators and to have pushed them to approve the act. While there are those who do not attribute much overall importance to this action, the "Capitol Crawl" of 1990 is seen by some present-day disability activists in the United States as a central act for encouraging the ADA into law.[39]
While Emotional Support Animals or Comfort Animals are often used as part of a medical treatment plan as therapy animals, they are not considered service animals under the ADA. These support animals provide companionship, relieve loneliness, and sometimes help with depression, anxiety, and certain phobias, but do not have special training to perform tasks that assist people with disabilities. Even though some states have laws defining therapy animals, these animals are not limited to working with people with disabilities and therefore are not covered by federal laws protecting the use of service animals.  Therapy animals provide people with therapeutic contact, usually in a clinical setting, to improve their physical, social, emotional, and/or cognitive functioning.
Medicaid provides health coverage to eligible low-income adults, children, pregnant women, and people who are older or who have disabilities. Each state has its own rules about who’s eligible, and what Medicaid covers. Some people qualify for both Medicare and Medicaid. To find out if you might be eligible for Medicaid in Texas, visit the Your Texas Benefits website.

Case law has been the most helpful in illuminating the implications of the ADA for websites.There have been lawsuits involving companies like Expedia, Hotels.com, Southwest Airlines, and Target as defendants and primarily featuring accessibility organizations as plaintiffs. These cases had mixed results, but each helped clarify the ADA's jurisdiction on the web. 
In 1986, the National Council on Disability had recommended the enactment of an Americans with Disabilities Act (ADA) and drafted the first version of the bill which was introduced in the House and Senate in 1988. The final version of the bill was signed into law on July 26, 1990, by President George H. W. Bush. It was later amended in 2008 and signed by President George W. Bush with changes effective as of January 1, 2009.[3]
In the employment setting, employers may be obligated to permit employees to bring their “service animal in training” into the workplace as a reasonable accommodation, especially if the animal is being trained to assist the employee with work-related tasks. The untrained animal may be excluded, however, if it becomes a workplace disruption or causes an undue hardship in the workplace.

The Fair Housing Act (FHA), as amended in 1988, applies to housing. Section 504 of the Rehabilitation Act of 1973 prohibits discrimination on the basis of disability in all housing programs and activities that are either conducted by the federal government or receive federal financial assistance. Title II of the ADA applies to housing provided by state or local government entities.
Auditory: The best approach for testing for this criterion is to turn the volume off on your machine and look at the website. This is mainly to focus on audio media elements such as videos. Do video elements contain captions, text transcripts, or a description of what the video contains and the purpose of the video? If the captions or text transcripts are not added to the video or the description of the video does not make sense, this can be an issue of ADA compliance.
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.

A person’s method(s) of communication are also key. For example, sign language interpreters are effective only for people who use sign language. Other methods of communication, such as those described above, are needed for people who may have lost their hearing later in life and do not use sign language. Similarly, Braille is effective only for people who read Braille. Other methods are needed for people with vision disabilities who do not read Braille, such as providing accessible electronic text documents, forms, etc., that can be accessed by the person’s screen reader program.
For people who are blind, have vision loss, or are deaf-blind, this includes providing a qualified reader; information in large print, Braille, or electronically for use with a computer screen-reading program; or an audio recording of printed information. A “qualified” reader means someone who is able to read effectively, accurately, and impartially, using any necessary specialized vocabulary.
Enough Time: Users have sufficient time to read and use the website’s content. If part of the website has a time limit, users are able to turn off the time limit, or they can adjust or extend it to at least ten times the default limit (unless the time limit is essential to the website’s functionality, such as auction websites like eBay). Content that moves, blinks, or automatically updates can be paused or stopped unless it’s essential to the website’s functionality.
We recommend following the Web Content Accessibility Guidelines (WCAG) as best practice on your site, which is what our platform uses as the foundation for our accessibility guidelines. To see how accessible your site is according to WCAG, request a website audit using the form on this page. Your PDF report will be emailed to you within one business day, so you can start assessing the conformance of your site quickly. 
State and local governments: in determining whether a particular aid or service would result in undue financial and administrative burdens, a title II entity should take into consideration the cost of the particular aid or service in light of all resources available to fund the program, service, or activity and the effect on other expenses or operations. The decision that a particular aid or service would result in an undue burden must be made by a high level official, no lower than a Department head, and must include a written statement of the reasons for reaching that conclusion.
First, these lawsuits will be very easy for plaintiffs to work up. The plaintiffs do not need any site inspection, experts or research. They can just surf the web from the convenience of their homes or offices. Marty says the "surf by" complaints could dwarf the "drive by" ADA lawsuits that looked for missing accessible parking spaces and other readily visible shortcomings.
Signed in 1990 at a time that most people hadn’t even used the Internet, the Americans with Disabilities Act does not explicitly regulate how websites need to follow nondiscrimination requirements. We now know that using the Internet is one of the most important ways for people with disabilities to fulfill their needs and desires. For many people with disabilities, especially impairments to sight and motion, visiting a store or other physical location can be a challenging experience. Online shopping, for example, allows people with disabilities to make the purchases they need easily and securely within the comfort of their own homes.
Allergies and fear of dogs are not valid reasons for denying access or refusing service to people using service animals. When a person who is allergic to dog dander and a person who uses a service animal must spend time in the same room or facility, for example, in a school classroom or at a homeless shelter, they both should be accommodated by assigning them, if possible, to different locations within the room or different rooms in the facility.
Animals such as miniature horses, pigs, and monkeys may be considered service animals. A carrier must decide on a case-by-case basis according to factors such as the animal’s size and weight; state and foreign country restrictions; whether or not the animal would pose a direct threat to the health or safety of others; or cause a fundamental alteration in the cabin service.17 Individuals should contact the airlines ahead of travel to find out what is permitted.
• Operable: Ensure not only that it's simple for users to navigate using a mouse, but also that it's easy to navigate using keyboard-only commands. Try pressing the “tab” key repeatedly to see whether you can access elements on your website using the keyboard alone. Many people who have motor disabilities, as well as people with visual impairments, rely on a keyboard. If your site relies on interaction by a computer mouse, you may want to seek a developer’s assistance in improving this aspect of accessibility.
The U.S. Department of Transportation enforces regulations governing transit, which includes ensuring that recipients of federal aid and state and local entities responsible for roadways and pedestrian facilities do not discriminate on the basis of disability in highway transportation programs or activities. The department also issues guidance to transit agencies on how to comply with the ADA to ensure that public transit vehicles and facilities are accessible.
Until the ADA is updated to address the special case of website accessibility, or the Department of Justice releases its website accessibility regulations, complying with WCAG 2.0 Level AA is the best way to ensure that people with disabilities have equal access to your website. The overview below is a great starting point about meeting the WCAG 2.0 Level AA recommendations.
The ADA requires that title II entities (State and local governments) and title III entities (businesses and nonprofit organizations that serve the public) communicate effectively with people who have communication disabilities. The goal is to ensure that communication with people with these disabilities is equally effective as communication with people without disabilities.
A. The ADA requires that service animals be under the control of the handler at all times. In most instances, the handler will be the individual with a disability or a third party who accompanies the individual with a disability. In the school (K-12) context and in similar settings, the school or similar entity may need to provide some assistance to enable a particular student to handle his or her service animal. The service animal must be harnessed, leashed, or tethered while in public places unless these devices interfere with the service animal's work or the person's disability prevents use of these devices. In that case, the person must use voice, signal, or other effective means to maintain control of the animal. For example, a person who uses a wheelchair may use a long, retractable leash to allow her service animal to pick up or retrieve items. She may not allow the dog to wander away from her and must maintain control of the dog, even if it is retrieving an item at a distance from her. Or, a returning veteran who has PTSD and has great difficulty entering unfamiliar spaces may have a dog that is trained to enter a space, check to see that no threats are there, and come back and signal that it is safe to enter. The dog must be off leash to do its job, but may be leashed at other times. Under control also means that a service animal should not be allowed to bark repeatedly in a lecture hall, theater, library, or other quiet place. However, if a dog barks just once, or barks because someone has provoked it, this would not mean that the dog is out of control.
These and other types of multimedia can present two distinct problems for people with different disabilities. People who are deaf or hard of hearing can generally see the information presented on webpages. But a deaf person or someone who is hard of hearing may not be able to hear the audio track of a video. On the other hand, persons who are blind or have low vision are frequently unable to see the video images but can hear the audio track.
As I mentioned above, under each WCAG 2.1 principle is a list of guidelines, and under each guideline are compliance standards, with techniques and failure examples at each level. Some guidelines include only Level A items; others include items for multiple levels of conformance, building from A to AAA. At each stage, you can easily see what more you would need to do to reach Level AA or AAA. In this way, many websites include elements at multiple levels of accessibility.
A landlord or homeowner’s association may not ask a housing applicant about the existence, nature, and extent of his or her disability. However, an individual with a disability who requests a reasonable accommodation may be asked to provide documentation so that the landlord or homeowner’s association can properly review the accommodation request.11 They can ask a person to certify, in writing, (1) that the tenant or a member of his or her family is a person with a disability; (2) the need for the animal to assist the person with that specific disability; and (3) that the animal actually assists the person with a disability.  It is important to keep in mind that the ADA may apply in the housing context as well, for example with student housing. Where the ADA applies, requiring documentation or certification would not be permitted with regard to an animal that qualifies as a “service animal.”
When it is not obvious what service an animal provides, only limited inquiries are allowed. Staff may ask two questions: (1) is the dog a service animal required because of a disability, and (2) what work or task has the dog been trained to perform. Staff cannot ask about the person’s disability, require medical documentation, require a special identification card or training documentation for the dog, or ask that the dog demonstrate its ability to perform the work or task.
