To make sure a website is accessible (1) have well-trained web developers create it, (2) evaluate it with software tools, and (3) have end users test it. Information about the importance of involving end users in site testing can be found at the World Wide Web Consortium's Web Accessibility Initiative site. UC developers should set evaluation tools to analyze sites for the WCAG 2.0 level AA standards. If they wish, they can also test for the section 508 standards.
