Best Practices – Digital Asset Guidelines – Rev 4 www.autocare.org | www.autocarevip.com | technology@autocare.org 44 Scoring outcomes The results from the atomic tests are aggregated across views and used along with the number of critical errors to assign an adjectival rating to the outcome. Testers will then use the guidance provided in the outcome, along with reasonable judgement of the context that the errors occur in to assign an accessibility score of the outcome. Potential thresholds for adjectival ratings of test results: Very Poor (0) - Any critical errors or less than 50% of related tests pass Poor (1) - No critical errors, approx. 50% to 79% of related tests pass Fair (2) - No critical errors, approx. 80% to 89% of related tests pass Good (3) - No critical errors, approx. 90% to 98% of related tests pass Excellent (4) - No critical errors, approx. 99% to 100% of related tests pass Overall scores After all outcomes have been scored, the ratings are averaged for a total score and a score by the functional category (ies) they support. Conformance at the Bronze level requires no critical errors and at least 3.5 total score and at least a 3.5 score within each functional category. Scoring holistic tests The points from holistic tests do not affect the scores of atomic tests. Rather a minimum number of holistic tests will need to be met in order to reach a Silver rating and additional holistic tests will be needed to reach a Gold rating. Getting a Silver or Gold rating requires a Bronze rating.
