Introduction
We have discussed how well we feel we are
doing in terms of Web site accessibility
Let us look at the accessibility for a number of
sectors of our community:
• UK University entry points
• JISC 5/99 project entry points
We will then mention possible approaches to
checking accessibility

Accessibility Testing Tools
How can we test accessibility of Web pages:
Automated Approaches
• Use of tools such as Bobby, WAVE, LIFT, etc.
• Often used for testing individual pages, but bulk
testing tools also available
• Won’t spot all possible errors (e.g. can spot
missing ALT tags, but not meaningless ones)
Manual Approaches
• Testing with users
• Can spot problems which tools won’t find
• Can be expensive

Example 1
UKOLN have added a simple interface to various Web-based
tools – simply append ,tools to a URL such as ,bobby or
,validate This is implemented using a Web server redirect

Example 2
The Bobby downloadable
application:
• Can analyse an entire
Web site
• Allows rules to be
switched off
• Is now a licensed
product
Question
If you have a large Web site is it
feasibleA centre
to test
accessible by checking individual pages?
