Some <strong>web</strong>sites showed excellent progress towards <strong>accessibility</strong>, for example, a German<br />
government site (BMAS) which was certified by BIK BITV (See Figure 4). The site performed well in<br />
automatic testing with <strong>on</strong>ly <strong>on</strong>e failure point, and was in the top five following manual testing. As well<br />
as meeting most <strong>accessibility</strong> criteria successfully, it additi<strong>on</strong>ally provided some informati<strong>on</strong> in<br />
multimedia using nati<strong>on</strong>al sign language.<br />

The 23 manually tested <strong>web</strong>sites from government and public bodies and two commercial <strong>web</strong>sites<br />
all showed that some effort had been made to meet <strong>accessibility</strong> guidelines, however over half failed<br />
Criteria 1.1.1. Other studies have shown that failures of n<strong>on</strong>-text equivalence are very comm<strong>on</strong> at<br />
WCAG 1 and WCAG 2.0.<br />
An in-depth analysis of WCAG 2.0 criteria was c<strong>on</strong>ducted in order to better distinguish between<br />
those sites making significant effort towards <strong>accessibility</strong> but having failures at the most basic levels<br />
affecting percepti<strong>on</strong>, specifically text equivalence and operati<strong>on</strong>, specifically keyboard operati<strong>on</strong>.<br />
It is recommended practice that <strong>web</strong>sites should meet WCAG 2.0 level AA and WCAG<br />
C<strong>on</strong>formance guidance further demands that there should be no failed criteria <strong>on</strong> any page showing<br />
the <str<strong>on</strong>g>c<strong>on</strong>formance</str<strong>on</strong>g> logo. Very few of the manually inspected <strong>web</strong>sites managed to meet all success<br />
criteria for level A. For the purposes of this study and to support further comparis<strong>on</strong> of multiple<br />
certified and self declared <strong>web</strong>sites we have given special attenti<strong>on</strong> to four of the success criteria<br />
from level A and drawn from the 10 most comm<strong>on</strong>ly failed criteria in order to represent different<br />
activities and the types of barrier faced by users with a range of different impairments. These<br />
include the most comm<strong>on</strong> failed Criteria 1.1.1 and three others that are operati<strong>on</strong>ally important to<br />
accessing core tasks of navigati<strong>on</strong>, c<strong>on</strong>tent and form filling:<br />
