The W3C WAI Research and Development Working Group (RDWG) invites you to share your experiences with metrics for measuring web accessibility beyond basic conformance to standards. In particular, RDWG is looking for valid, reliable, and practical metrics to measure the impact of accessibility issues on people with disabilities. These will be discussed in an online Symposium on 5 December 2011. More information will be available from: http://www.w3.org/WAI/RD/2011/metrics/

RDWG Symposia bring together researchers and practitioners interested in a particular aspect of web accessibility to advance research in that area. With this Symposium, we will collect current research, synthesize ideas in a teleconference, and provide a roadmap for future work on web accessibility metrics. The Symposium proceedings and report will be available publicly online afterward.

*If you are interested in contributing to this Symposium*, please see the *Call for Papers*.
