On July 27, 2009, Laura Wesley wrote a very good article on Why government websites (still) suck. In her article, Laura explains a number of the practical and systemic causes for the slow pace of improvements to government sites. Laura also provides a list of six federal government sites, expanded to seven in the comments to her article, whose developers and designers she commends for the work they have done.
Wondering how accessible the sites that Laura commends are, I performed a very preliminary accessibility audit, from the perspective of a blind screen-reader user on two of the sites, and included one site of my own. The three sites are Health Canada, Citizenship and Immigration Canada, and Copyright Consultations (the site I chose).
It is important to note that the following web-site evaluations are by no means exhaustive, and were not performed against any particular accessibility guideline. The following comments are reflective of my own user experience of the sites using the Firefox 3.5.2 web-browser and the JAWS 10.0.1154 screen-reader.
