Evaluation Methodology

Please, read carefully the disclaimer before any use of this curriculum.

Overview

Introduction

In several European countries, organizations working with disability groups have developed labeling schemes. Each of the schemes is based on a methodology for testing the conformance to the criteria of the scheme. But in order to do Web Accessibility validation on a European level, one needs a common evaluation methodology, which has to deal with topics such as scoping, sampling, testing, reporting, etc.
This module concentrates on a possible approach for testing. It presents a set of harmonised tests that could build a basis for a common European evaluation methodology.

Objectives

The objective of this chapter is to provide the reader with a set of tests checking conformance to WCAG 1.0 priority 1 checkpoints. The approach follows a synthesis consolidated from the Unified Web Evaluation Methodology 0.5 ([UWEM]) and the tests used in three existing evaluation methodologies of schemes already used in praxis: AccessiWeb ([ACCESSIWEB]), Drempelvrij.nl ([DREMPELVRIJ]) and MEWA ([MEWA]).

Contents

How to use

Each of the tests listed below consists of:

Each of the tests has three possible outcomes:

In order to check conformance of a web page, one has to check all the tests. A web page is considered to have passed the evaluation as a whole if, and only if, the outcome of all tests is either "Pass" or "Not Applicable" - the total "Fail" count has to be equal to zero.

Evaluation Tests

WCAG 1.0 Checkpoint 1.2

No tests available.
Explanation

The only circumstance in which the current scheme may permit the use of a server-side image map is where the number of distinct active regions makes a client-side image map impractical; however, that is precisely the situation in which providing "redundant text links" for each active region would also be impractical. In such a case, the scheme requires instead that a full equivalent alternative be provided for any such server-side image map, in accordance with WCAG Checkpoint 11.4. Thus, there is no remaining situation under this scheme where WCAG 1.0 Checkpoint 1.2 could actually be applicable, so no explicit testing against it arises.

WCAG 1.0 Checkpoint 14.1

No tests available.
Explanation

According to the data provided, this checkpoint is only evaluated by one test in one of the three existing schemes. Accordingly, no test has been included for it. Indeed, it may be noted that this is quite a difficult checkpoint to evaluate in an objective manner. Nonetheless, it would be appropriate for testing against this checkpoint to be reviewed further in the context of the ongoing development of UWEM.
