Success Criteria shall:
1. Address a situation where a user with a disability will be disproportionately disadvantaged (as compared to a user without a disability) if the criteria is not met.
2. Be testable through automated or manual processes.
[Jason] They should be as reliably testable as possible, while achieving their intended purpose and benefit.
3. Describe the specific condition required to meet the criteria, not the method to address the criteria.
4. Utilize the WCAG 2.0 A/AA/AAA level structure.
5. Ensure for revised Success Criteria that pages that meet the revised guidance continue to meet the corresponding WCAG 2.0 Success Criteria.
6. Apply to all content, unless specific exceptions are included in the success criteria (e.g. "except interruptions involving an emergency").
[Jason] Where a success criterion applies to only some types of content or only under specific conditions, such conditions should be stated explicitly (e.g., “If non-text content is time-based media”).
7. Apply across technologies to the extent possible. (Technology-specific issues should usually be addressed in Techniques.)
[Jason] Should read “to the greatest extent possible”.
8. Avoid creating a requirement for something that is already required by an existing Success Criteria.
[Jason] Should read “criterion” at the end of the sentence.
9. Have Success Techniques which demonstrate that the Success Criteria is reasonable and implementable, using common formats, user agents, and assistive technologies.
[Jason] Should read “the success criterion is”.

Success Criteria should:
1. Be as broad as possible, but specific enough not to become a 'catch-all' for any given requirement.
2. Use glossary definitions to simplify and shorten all Success Criteria for shared or ambiguous terms.
