co-presented by: Shadi Abou-Zahra

Session Summary

Learn how ACT rules help you, and the tools you use, and how we can work together to answer the tough questions in WCAG.


WCAG 2.2 will introduce new test rules, written using the ACT Rules Format. In this class, taught by ACT co-facilitators Wilco Fiers and Mary Jo Mueller, and W3C staff contact Shadi Abou-zahra teach you what these ACT rules are, how they work, and how testing tools, and methodologies (like Trusted Tester) use them to provide more consistently in accessibility testing. We will do this by going through example ACT rules, and towards the end we will work with students to come up with a few rules of their own.
