1. Web Accessibility National Transition Strategy
§ Agencies must update all government websites (as specified within scope under the NTS) to WCAG 2.0 conformance • Level A (Single A) by 31 December 2012 • Level AA (Double A) by 31 December 2014 • To claim conformance websites must meet all five WCAG 2.0
conformance requirements.
§ Agencies are encouraged to seek WCAG 2.0 Level AA conformance from the outset, but must still meet the minimum requirements of the NTS (including Level A conformance by December 2012).
Australian Government Web Guide - Accessibility
Relax and let me explain…
Some very clever people wrote guidelines for
improving access to digital informa-on.
The Federal Government decided it is
mandatory for all departments to implement these
guidelines.
All government departments –
Federal, State and Territory – must implement these guidelines by 31 December 2014.
The guidelines allow for three levels of conformity: 1. Single A 2. Double A 3. Triple A “Single A” is the minimum standard. “Triple A” is the gold standard. “Double A” is the happy-medium.
“Double A” is not a battery size.

Number of Success Criteria
Level of compliance
Double A compliance has a total of 36 Success Criteria
• 1. Perceivable: Informa-on and user interface components must be presentable to users in ways they can perceive. Principle
• 1.1 Text Alterna>ves: Provide text alterna-ves for any non-‐text content so that it can be changed into other forms people need, such as large print, braille, speech, symbols or simpler language.
Guideline
• 1.1.1 Non-‐text Content: All non-‐text content that is presented to the user has a text alterna-ve that serves the equivalent purpose, except for the situa-ons listed below. (Level A)

✪ Some of these criteria can only be met through design. We can tell the graphic designer/web developer about them, but we can’t do it ourselves.
Adaptable content can be: • forms • tables • schedules • text reading order
Alternatives can be: • text directions • text description • captions Ø programmatic cues
