About this report

The Bobby report presents an accessibility evaluation grouped by the three priority levels defined by the Web Access Initiative (WAI), as well as browser compatibility and download statistics. As an automated evaluation tool, Bobby is able to detect many accessibility problems and to highlight other possible problems that must be checked. A "Bobby" hat in the original page (if displayed) indicates that Bobby was able to detect a Priority 1 problem with accessibility. A question mark indicates a Priority 1 item that needs to be checked by the user. Follow the links provided in the report to get details about any problem reported, including how to repair it, if needed. For more information on the report, please access our online documentation.

To be Bobby Approved, a page must pass all of the Priority 1 accessibility checkpoints established by the WAI.

Download Time

The following three-column table gives download time statistics for the images, applets, and objects on this page. The first column contains the URL of each item, the second column the item size in kilobytes, and the third column the approximate download time for each item when using a 28,800 baud modem. At the end of the report, an arbitrary delay of 0.5 seconds is added for each file to account for slow-downs caused by HTTP connection times.
