Accessibility Cheat Sheets & Checklists

When purchasing digital products and services, make sure to ask vendors to provide a Voluntary Product Accessibility Template (VPAT), which details how the product meets or does not meet the accessibility standards linked above.

For more information, see the Procurement policy regarding electronic and information technology.

Web Accessibility Checkers


The University has made this tool available for official university use by staff and faculty for public university websites (including sites in AEM, Wordpress, other content management platforms or hand-coded websites).



WAVE browser extension*

The WAVE Chrome and Firefox extensions allows you to evaluate web content for accessibility issues directly within Chrome and Firefox browsers.


Siteimprove browser extension for Chrome*

The Siteimprove Accessibility Checker is your tool to evaluate any web page for accessibility issues at any given time. It provides intuitive, visual feedback about your content by highlighting detected issues right on the page

* Note: automated accessibility checkers only catch approximately 30% of accessibility issues, and can sometimes give you false positives and false negatives, which is why it is important to also manually test your website.


Manual Accessibility Testing Issue Tracker, v1.0 tool

Use this tool to record, prioritize, and track progress on fixing web accessibility issues you encounter while manually testing your website(s).
