A.4 WCAG 3.0 Scoring Each outcome has methods associated with different technologies. Each method contains tests and techniques for meeting that outcome. Testers can test the accessibility of new and emerging technologies that do not have related methods based on the outcome. Scoring atomic tests In most cases, testing individual objects will result in binary, pass / fail outcome for each element. This leads to either a pass / fail or a percentage rating depending on the test. A rating scale may be provided for some tests to allow the tester to assign a quality judgement of an element or block of content. Whether scoring is binary (pass/fail) or uses rating scales will depend on the method, outcome, and technology. Binary scoring works well when the unit being tested has clear boundaries and pass/fail conditions. Rating scales work better when the unit being tested does not have clear boundaries, when evaluating success requires a quality judgement, or when the test includes gradations of quality. Each of these results can then be assigned a percentage or averaged to inform the overall score of an outcome. Test results for views: • Tests that result in a pass or fail condition will be assigned a 100% or 0% • Tests at the element level that can be consistently counted will be assigned a percentage (number passed / total number of instances) • Tests that apply to content without clear boundaries will be scored using a rating scale. The rating scales may vary based on the test and may be presented as numeric scale, an adjectival rating or a rubric. Each of these can be converted into a percentage to make it easier to compare across tests. In addition, critical errors within selected processes will be identified and totaled. Any critical errors will result in score of very poor (0)
