Web Accessibility Standards AAA

Web accessibility standards aa are designed to enable users with various disabilities to access digital content. These requirements are internationally-adopted and regulated by legislation.

The World Wide Web Consortium (W3C) developed Web Content Accessibility Guidelines (WCAG) to help address this need. WCAG comprises four main principles with multiple success criteria.

Level A

The Web Content Accessibility Guidelines (WCAG) are internationally recognized standards that make it easier for users with disabilities to access web content. Developed by the World Wide Web Consortium (W3C), the guidelines are based on four main principles: perceivable, operable, understandable, and robust. These principles are incorporated into 78 testable statements called success criteria. Websites are generally evaluated against these criteria, with different levels of compliance reflected in how many success criteria are met. WCAG guidelines are divided into three levels of conformance: A, AA, and AAA. Achieving level A is often considered the minimum requirement.

WCAG 2.0 was released in 2008. It was the first version of the guidelines to be adopted by governments, and is often used as a basis for non-discrimination regulations. It was replaced by a new version, WCAG 2.1, in 2018. This new version incorporates feedback from the accessibility community and is designed to be forward-looking.

Level A

As the name suggests, WCAG 2.0 Level A is the minimum standard for web accessibility. This level includes basic guidelines for making websites accessible to the majority of people with disabilities, including those using assistive technology. It includes basic requirements such as ensuring that the content can be read with text-to-speech software, that images have alternative descriptions, and that forms contain descriptive labels. This is the most common level of WCAG compliance, and the level at which most websites strive to achieve.

AA

WCAG 2.1 Level AA is the mid-range of compliance levels, and it provides additional guidelines that help websites be more accessible for a wider range of disabled people. It includes all of the guidelines from level A, plus requirements such as captions for video and audio content, device orientation independence, and color contrast of 7:1. This is the level at which most ADA websites comply.

AAA

Currently, there are no regulations in Canada that require businesses to adhere to WCAG 2.1 Level AA. However, the Canadian Human Rights Commission enforces a number of provisions that prohibit discrimination based on disability. It is important to understand the importance of web accessibility standards aa and how they relate to ADA compliance to avoid any penalties or fines that may be imposed under the law.

Making your website accessible to people with disabilities can increase your traffic, improve customer satisfaction, and boost brand credibility. It is also the right thing to do, as people with disabilities represent a market worth over $1.9 trillion in disposable income every year. In addition, the ADA requires that public sector bodies make their websites and mobile applications WCAG 2.0 AA compliant. This is especially true for organizations that receive federal funding or grants. The government published Understanding WCAG 2.1 to guide compliance, and third-party assessment tools like WebAIM can evaluate a website against the AA level of WCAG. Achieving this level of WCAG compliance is not easy, but it is possible with the right knowledge and the assistance of a professional. Taking the time to address WCAG compliance is well worth it.
