The Section 508 criteria for Web-based technology and information systems are based on access guidelines developed by the Web Accessibility Initiative of the World Wide Web Consortium (W3C).
Accessibility Checkpoints are designed to help you easily locate the areas of your Web site that require special attention according to the W3C (World Wide Web Consortium ) Web Content Accessibility Guidelines. They do not necessarily indicate whether or not your Web site conforms to the guidelines.
You can add accessibility checkpoints to help you quickly identify areas of your Web site that may not conform to the W3C Web Content Accessibility Guidelines. You can add automatic accessibility checkpoints to each page in your test, or you can add individual accessibility checkpoints to individual pages or frames.
