5 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

6 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 Double A is not a battery size. 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.

8 WCAG 2.0 structure 4 Principles 12 Guidelines 61 Success Criteria

9 Principles 1. Perceivable 2. Operable 3. Understandable 4. Robust

10 Guidelines Perceivable Operable Understandable Robust 1.1 Provide text alterna-ves for non- text content 1.2 Provide alterna-ves for -me- based media 2.1 Make all func-onality available from a keyboard 2.2 Provide users enough -me to read and use content 3.1 Make text content readable and understandable 3.2 Make Web pages appear and operate in predictable ways 4.1 Maximize compa-bility with current and future soyware and hardware 1.3 Create content that can be presented in different ways 2.3 Do not design content in a way that is known to cause seizures 3.3 Help users avoid and correct mistakes 1.4 Make it easier for users to see and hear content 2.4 Provide ways to help users navigate and find content

11 Success criteria Level of compliance Single A Double A Triple A Perceivable Operable Understandable Robust TOTAL 23 Single A + 13 Double A + 23 Principles of accessibility Number of Success Criteria Double A compliance has a total of 36 Success Criteria

12 3. WCAG 2.0 Level AA requirements This is where we Principle come in 1. Perceivable: Informa-on and user interface components must be presentable to users in ways they can perceive. Guideline 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. Success Criteria 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)

13 Perceivable The first principle.

14 Text Alternatives Perceivable 1.1 Text Alterna-ves Non-text content can be: charts diagrams pictures animations maps interactive design Text alternatives can be: text description data table text transcript This is related to 1.2 Time-based Media

15 Writing Text Alternatives Alternative text must be equivalent and meaningful. Further information: Understanding SC Image ALT Tag Tips Complex Images Yes Provide a text alterna-ve Is the content func-onal? No Hide the content in the background

16 Time-based Media Perceivable 1.2 Provide alterna-ves for -me- based media AA AA Time-based media can be: audio-only video-only live audio content synchronised media animations Alternatives can be: text transcript audio description captions text description This is related to 1.1 Text Alternatives

17 Writing Media Alternatives Media alternatives must be accurate and detailed. Further Information: Understanding SC Understanding SC Understanding SC Understanding SC Understanding SC Video Captions and Audio Transcripts Yes Provide a brief ALT descrip-on and refer back to the main text Is the content repe--ve? No Provide a media alterna-ve

18 Adaptable Perceivable 1.3 Create content that can be presented in different ways 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

20 Distinguishable Perceivable 1.4 Make it easier for users to see and hear content including separa-ng foreground from background AA AA AA 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.
