- NC State has a site license for LIFT for Dreamweaver (Windows and
Macintosh) and LIFT for Frontpage from UsableNet.
LIFT assists web developers in automating website accessibility and
usability testing, repair and delivery. Please contact ITD to
obtain a copy of LIFT.
- Evaluating the accessibility of a web page with a validator can be
analogous to using spell check in a word processor. The author may
still have to determine if the web page is functional and has good
usability. One way to check for this is by using a screenreader. Demonstration
versions of screenreaders can be downloaded from GW
Micro or Freedom Scientific.
Alternately, you can install the JAWS
Network Client from the NCSU JAWS Server to use on a limited basis
to test webpages.
- The first web accessibility assessment tool, named Bobby,
was developed by the Center for Applied Special Technology (CAST),
and is available through a web interface or as downloadable software.
Bobby will check your web page(s) for accessibility, and provide a
detailed report showing specific areas needing improvement, including
HTML code. The current version, Bobby WorldWide, can assess pages based
on either the Web Content Accessibility Guidelines (WCAG) 1.0 or the
U.S. Section 508 Guidelines. Bobby is now owned by the Watchfire Corporation.
It is still available as a free online tool.
While Bobby is an assessment tool, it is an excellent resource
to help learn about accessibility issues. Bobby will not tell you
entirely whether your page is accessible, but will instead point
out the areas that may need attention. Bobby also provides examples
and help solving the problems it identifies.

WAVE (Web Accessibility Versatile Evaluator), is a web-based application
developed at The Institute on Disabilities at Temple University.
It's similar to Bobby, but its output focuses on a graphical report,
rather than on the HTML code, so it may be easier for some content
developers to use. It also identifies the reading order of all the
elements on the page, which Bobby does not. One drawback is that
it only works with single pages.

A-Prompt was collaboratively developed by the Adaptive Technology
Resource Centre (ATRC) at the University of Toronto and the TRACE
Center at the University of Wisconsin. It is available for download
for Windows-based computers and can evaluate and fix pages using
either the WCAG 1.0 Guidelines or the U.S. Section 508 Standards
(in English or French). Its distinguishing feature is its accessibility
wizard, which prompts developers with specific recommended fixes
and actually implements the fixes.
