What's New with WCAG 2.0
- Applies to more advanced Web technologies
- current, future, and non-W3C
- More precisely testable
(still need human)
- Adaptable for situations
- Extensive supporting materials,
practical implementation guidance
WCAG 2.0 Differences from WCAG 1.0
- WCAG 1.0
- Guidelines
- Checkpoints
Priority 1, 2, 3
- WCAG 2.0
- Principles
- Guidelines
- Success Criteria
Level 1, 2, 3
Principles
- Perceivable
- Operable
- Understandable
- Robust
Testable Success Criteria Example
- WCAG 1.0 Checkpoint 2.2
Ensure that foreground and background color combinations provide sufficient contrast when viewed by someone having color deficits...
- WCAG 2.0 Success Criteria
1.4.1
Text or diagrams, and their background, have a luminosity contrast ratio of at least 5:1
Levels Example
- WCAG 2.0 Success Criteria
- 1.4.1 Text or diagrams, and their background, have a luminosity contrast ratio of at least 5:1 [Level 2]
- 1.4.3 Text or diagrams, and their background, have a luminosity contrast ratio of at least 10:1 [Level 3]

Baseline in WCAG 2.0
- Purpose
- Flexibility for different situations today
- Flexibility over time
- For example, SVG (Scalable Vector Graphics)
- WCAG Working Group is refining baseline (expect some changes)
List of Web Technologies
- Technologies
- For example: HTML, CSS, etc...
- That are accessible and that users have available
- An established list of Web technologies that an author can use to create accessible Web content
- Authors can use technologies outside of baseline, if content is usable without those technologies; that is, used for enhancement
Transitioning from 1.0 to 2.0
- Most sites that conform to WCAG 1.0 should not require significant changes
- Accessibility issues basically the same
- Different approach takes some time to learn
