Hi Jim,
While it is a good idea to run through some pages using a matrix of screen
access tools, OS, browser and, perhaps, some plug-ins, this process is slow and
depending upon the person judging what is and is not accessible, can provide
ambiguous results.
The best thing to do is to become somewhat familiar with the Section 508
standards and the guidelines published by the Web Accessibility Initiative at
W3C (http://www.w3c.org/wai). With a general understanding of the standards and
guidelines, you should then use a web validation tool (there are a number of
free ones which I am told are very good) and let the software find your access
problems. You can then either send a report to your web developers with a list
of requisite changes or, using a remediation tool, fix the problems as you find
them.
If you can demonstrate that the testing tools find no accessibility problems
but some screen readers and other access technologies perform badly on the same
pages, it is incumbent upon the authors of the AT to fix the bugs in their
software to bring themselves into compliance with the standards and guidelines.
If you ensure that JAWS together with IE performs up to the standards, it may
not be the case for a different Windows screen reader, a Macintosh or the orca
screen reader with Firefox on GNU/Linux distros. Fixing a page to work with one
AT will likely break another and you can spend an eternity chasing a solution
for all possibilities but, sticking to the standards and guidelines puts the
onus onto the browser and AT publishers to comply with an accepted set of rules.
