Accessibility Insights

    Creator: Microsoft

    Date Updated: January 6, 2022


    Accessibility Insights provides an open-source tool that uncovers accessibility issues in websites and apps. This resource is particularly useful for web developers and those in charge of your library website. Accessibility Insights is available for Android devices, as a browser extension, and for Windows.

    The information is summarized from Microsoft’s Accessibility Insights.

    Testing Options

    Accessibility Insights offers several features web developers can use to check their websites for accessibility issues or barriers. The options differ depending on the version used (for Android, a browser extension, or Windows).

    FastPass (available in all versions) checks for common accessibility issues by running two steps – automated checks and manual tests for tab stops. It automatically checks if the website complies with Web Content Accessibility Guidelines (WCAG). Manual test for tab stops reviews and provides instructions to fix items like tab stops, incorrect tab order, etc.

    Assessment (available in the browser extension option) tests if your website is compliant with the Web Content Accessibility Guidelines (WCAG). The review helps you check your website for keyboard accessibility, headings, links, language, multimedia, etc.

    Automated Checks (available in the Windows version) test if apps are accessible according to several accessibility rules. This can be used together with FastPass.

    The Color Contrast Analyzer (available in the Windows version) assesses if there are any low colour contrast ratio errors on your website. As determined by WCAG, the contrast ratios should be at least 4.5:1.
