The WCAG guidelines are divided into three levels: A, AA, and AAA. Each level has specific requirements to ensure the accessibility of digital services.
-
Level A: This level contains the basic requirements for accessibility. It addresses the most urgent issues that make websites and apps unusable for people with disabilities.
Example: A form without text explaining what to fill in the fields. This is problematic for people using screen readers because they cannot see what should be entered in each field.
-
Level AA: This level includes additional requirements that enhance the user experience for more people with disabilities. It ensures that a website is easier to use for most people, including those with visual, motor, or cognitive impairments.
Example: Adding text descriptions for images, so people with visual impairments know what is shown in the image. It is also important that a website works well with a keyboard so people without a mouse can use the site.
-
Level AAA: This level sets the strictest requirements and is considered a best practice for digital accessibility. It focuses on optimizing the user experience for people with various types of impairments. However, this level is not required under the EAA.
Example: Providing full audio descriptions for videos, so people with visual impairments can fully understand the content of the video.
Note: The EAA requires businesses to comply with at least level AA of the WCAG 2.1 guidelines. This ensures that your website or app is accessible to most users with disabilities.
