What does AVT stand for in the context of accessibility?

In the context of accessibility, AVT stands for Automated Verification Testing. This practice involves using tools and software to automatically check web content against established accessibility standards and guidelines. The goal of AVT is to identify accessibility issues more efficiently than manual testing alone, helping organizations to ensure that their websites or applications are compliant with accessibility regulations, such as the Web Content Accessibility Guidelines (WCAG).

Automated Verification Testing is particularly valuable because it can quickly cover a wide range of issues, such as contrasting colors, missing alt text for images, and semantic structure of HTML elements. However, while AVT is an essential part of accessibility assessment, it should ideally be supplemented with manual testing to catch more nuanced issues that automated tools might miss, such as usability aspects for real users with disabilities.

The other choices describe concepts that are not widely recognized as standard terms within the accessibility community, making Automated Verification Testing the most accurate and relevant answer here.
