Abstract

Web accessibility for people with disabilities is a highly visible area of work in the field of ICT accessibility, including many policy activities in several countries. The commonly accepted guidelines for web accessibility (WCAG 1.0) were published in 1999 and have been extensively used by designers, evaluators and legislators. A new version of these guidelines (WCAG 2.0) was published in 2008. In this paper we point out the main challenges that WCAG 2.0 raises for web accessibility evaluators: the concept of “accessibility supported technologies”; success criteria testability; technique and failure openness, and the aggregation of partial results. We conclude the paper with some recommendations for the future.
