A recent exchange on Twitter has motivated me to write about the contribution published surveys on web site accessibility make towards understanding and addressing the problems that hold back web accessibility. I’ve read, and continue to read, many, many papers presenting the results of surveys of web sites, and I think we need surveys to look beyond just the data and instead delve more deeply into why the results are as they are. We’ve gone way beyond the point where a paper simply reporting that a study of x web sites from y sector revealed ‘disappointing’ levels of accessibility provides anything more than a minor contribution. Surveys need to look at process not product.
Recently, I’ve been doing work looking at accessibility implications of electronic assessment (e-assessment for short). E-assessment covers any use of electronic means, often a web interface, to ask questions of and gather information or evidence from a user in order to provide some form of assessment of their levels of knowledge, skills or competencies in a particular subject or activity.
From a technical perspective, this is related to electronic survey accessibility, which in turn could easily be seen as a real world instance of accessible web form design plus accessible navigation; and therefore covered by a subset of WCAG 2.0. However, it’s not as straightforward as that.
