“…Even though most of the evaluations are based on the Web Content Accessibility Guidelines (WCAG) (World Wide Web Consortium, 1999, they are mostly oneoff studies using specialized methodologies. To deal with this problem, the development of a Unified Web Evaluation Methodology (UWEM) (Velleman, Strobbe, Koch, Velasco, & Snaprud, 2007;Web Accessibility Benchmarking Cluster, 2007) was initiated by the European Commission.…”

“…One of the deliverables from the Web Accessibility Benchmarking Cluster (WAB) is the development of a standard Unified Web Evaluation Methodology (UWEM) [23] which can be adopted by organisations to assist interpretation of WCAG 1.0 and 2.0. The documentation contains a range of procedures to validate WCAG checkpoints with applicability criteria, expected results for pass or fail and information if the check is fully automatable.…”

This paper describes the design and development of a web accessibility knowledge management tool, known as the Accessibility Evaluation Assistant (AEA) designed to assist novice auditors in the process of an accessibility evaluation. The software incorporates a structured walkthrough approach to guide the auditor through a series of checks for established accessibility principles with the goal of conducting a comprehensive accessibility evaluation. The tool also offers the functionality to tailor the evaluation and prioritise checks based on the needs of two different user groups, or the specific content features of the website. The tool has recently been trialled with a group of 38 undergraduate computing students studying an Accessibility and Adaptive Technologies module with the aim of assessing its reliability and accuracy to validate the method. Some initial conclusions about the reliability and validity of the method and the pedagogical implications of the tool are presented. The results will help highlight the checks that can easily be verified by novices, and those that require a more detailed understanding of accessibility; require informed judgement; or are open to individual interpretation.

Effective evaluation of websites for accessibility remains problematic. Automated evaluation tools still require a significant manual element. There is also a significant expertise and evaluator effect. The Structured Walkthrough method is the translation of a manual, expert accessibility evaluation process adapted for use by novices. The method is embedded in the Accessibility Evaluation Assistant (AEA), a web accessibility knowledge management tool. Previous trials examined the pedagogical potential of the tool when incorporated into an undergraduate computing curriculum. The results of the evaluations carried out by novices yielded promising, consistent levels of validity and reliability. This paper presents the results of an empirical study that compares the reliability of accessibility evaluations produced by two groups (novices and experts). The main results of this study indicate that overall reliability of expert evaluations was 76% compared to 65% for evaluations produced by novices. The potential of the Structured Walkthrough method as a u seful and viable tool for expert evaluators is also examined.
