Comparison of web accessibility within japanese educational institution websites

The authors investigate how well current Japanese educational institution Web sites conform to Japanese Industrial Standard (JIS) X 8341-3 in which design guidelines for Web accessibility are described. Conformance checking results by an automated tool are compared among 4 educational institution categories: universities, high schools, junior high schools and elementary schools. It is found that i) university site top pages include problems the most but are relatively the best in the conformance to JIS 5.4ab guidelines in terms of #problems/#<img>s ratio, and ii) site designers should pay more attention to some specific guidelines because those guidelines are less conformed to in their top pages of each school category.
