CAST offers Bobby as a free public service in order to further its mission to expand opportunities for people with disabilities through the innovative uses of computer technology. Bobby is only one step in the process of making a site accessible to as many people as possible. Since there are some important aspects of accessible Web page design that can not yet be tested by Bobby, CAST recommends that Web developers use Bobby only as a first step to ensure accessible Web page design. Please review the How-to section and the Bobby Documentation for more information. Bobby also analyzes Web pages for compatibility with various browsers.
Analysis is based on documentation from browser vendors when available.
Bobby automatically checks sites for compatibility with HTML 4.0. For accessibility and tag compatibility with browser specifications other than HTML 4.0, use the Advanced Options . Once your Web site receives a Bobby Approved rating, you are entitled to use a Bobby Approved icon on your site.
