WCAG 1.0 Checkpoints

Status at 21 october 2008 (OpenACS 5.4.3 and .LRN 2.4.1)

A summary for US Section 508 is available at LINK_TO_WIKIPAGE 

See Checklist of Checkpoints for Web Content Accessibility Guidelines 1.0 for details

How to read this document

Accessibility Compliance Level

  • Level A means that all the priority 1 checkpoints are in state "Y" or "n/a".
  • Level AA means that level A has been reached + all the priority 2 checkpoints are in state "Y" or "n/a"
  • Level AAA means that level AA has been reached + all the priority 3 checkpoints are in state "Y" or "n/a"

Checkpoint Status

  • Y: 100% of the pages comply with the checkpoint or the exceptions are clearly identified and listed in the accessibility statement.
  • N: NOT 100% of the pages comply with the checkpoint, exceptions are NOT identified.
  • n/a: the situation described in the checkpoint is not applicable in ANY of the pages

OpenACS-specific Techniques for Checkpoints

Each checkpoint is identified with a number which links to the OpenACS-specific techniques to apply it.

 

Note: the  links are dead right now, but will point to OpenACS-specific techniques to implement them.

Priority 1 checkpoints

In General (Priority 1) Yes No N/A
1.1 Provide a text equivalent for every non-text element (e.g., via "alt", "longdesc", or in element content). This includes: images, graphical representations of text (including symbols), image map regions, animations (e.g., animated GIFs), applets and programmatic objects, ascii art, frames, scripts, images used as list bullets, spacers, graphical buttons, sounds (played with or without user interaction), stand-alone audio files, audio tracks of video, and video.  Y    
2.1 Ensure that all information conveyed with color is also available without color, for example from context or markup.  Y    
4.1 Clearly identify changes in the natural language of a document's text and any text equivalents (e.g., captions).  Y    
6.1 Organize documents so they may be read without style sheets. For example, when an HTML document is rendered without associated style sheets, it must still be possible to read the document.  Y    
6.2 Ensure that equivalents for dynamic content are updated when the dynamic content changes.      n/a
7.1 Until user agents allow users to control flickering, avoid causing the screen to flicker.  Y    
14.1 Use the clearest and simplest language appropriate for a site's content.  

 N

e.g.: portlet

 
And if you use images and image maps (Priority 1) Yes No N/A
1.2 Provide redundant text links for each active region of a server-side image map.      n/a
9.1 Provide client-side image maps instead of server-side image maps except where the regions cannot be defined with an available geometric shape.      n/a
And if you use tables (Priority 1) Yes No N/A
5.1 For data tables, identify row and column headers. Y     
5.2 For data tables that have two or more logical levels of row or column headers, use markup to associate data cells and header cells.  Y    
And if you use frames (Priority 1) Yes No N/A
12.1 Title each frame to facilitate frame identification and navigation.  Y    
And if you use applets and scripts (Priority 1) Yes No N/A
6.3 Ensure that pages are usable when scripts, applets, or other programmatic objects are turned off or not supported. If this is not possible, provide equivalent information on an alternative accessible page.  

 N

And if you use multimedia (Priority 1) Yes No N/A
1.3 Until user agents can automatically read aloud the text equivalent of a visual track, provide an auditory description of the important information of the visual track of a multimedia presentation.      n/a
1.4 For any time-based multimedia presentation (e.g., a movie or animation), synchronize equivalent alternatives (e.g., captions or auditory descriptions of the visual track) with the presentation.      n/a
And if all else fails (Priority 1) Yes No N/A
11.4 If, after best efforts, you cannot create an accessible page, provide a link to an alternative page that uses W3C technologies, is accessible, has equivalent information (or functionality), and is updated as often as the inaccessible (original) page.

Priority 2 checkpoints

In General (Priority 2) Yes No N/A
2.2 Ensure that foreground and background color combinations provide sufficient contrast when viewed by someone having color deficits or when viewed on a black and white screen. [Priority 2 for images, Priority 3 for text].  Y    
3.1 When an appropriate markup language exists, use markup rather than images to convey information.  Y    
3.2 Create documents that validate to published formal grammars.  Y    
3.3 Use style sheets to control layout and presentation.  Y    
3.4 Use relative rather than absolute units in markup language attribute values and style sheet property values.  

  N

calendar

 
3.5 Use header elements to convey document structure and use them according to specification.  Y    
3.6 Mark up lists and list items properly.  Y    
3.7 Mark up quotations. Do not use quotation markup for formatting effects such as indentation.  Y    
6.5 Ensure that dynamic content is accessible or provide an alternative presentation or page.      n/a
7.2 Until user agents allow users to control blinking, avoid causing content to blink (i.e., change presentation at a regular rate, such as turning on and off).  Y    
7.4 Until user agents provide the ability to stop the refresh, do not create periodically auto-refreshing pages.  Y    
7.5 Until user agents provide the ability to stop auto-redirect, do not use markup to redirect pages automatically. Instead, configure the server to perform redirects.  Y    
10.1 Until user agents allow users to turn off spawned windows, do not cause pop-ups or other windows to appear and do not change the current window without informing the user.  Y    
11.1 Use W3C technologies when they are available and appropriate for a task and use the latest versions when supported.  Y    
11.2 Avoid deprecated features of W3C technologies.  Y    
12.3 Divide large blocks of information into more manageable groups where natural and appropriate.      n/a
13.1 Clearly identify the target of each link.  Y    
13.2 Provide metadata to add semantic information to pages and sites.  Y

And if you use applets and scripts (Priority 2) Yes No N/A
6.4 For scripts and applets, ensure that event handlers are input device-independent.   Y    
7.3 Until user agents allow users to freeze moving content, avoid movement in pages.      n/a
8.1 Make programmatic elements such as scripts and applets directly accessible or compatible with assistive technologies [Priority 1 if functionality is important and not presented elsewhere, otherwise Priority 2.]   Y
