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.

Priority 1 Accessibility

This web page does not contain any Priority 1 accessibility errors that Bobby can detect. However, certain items require human judgment; these are listed below. Please review these items; if none of these apply to your page, it qualifies for Bobby Approved status.

User Checks

User checks are triggered by something specific on the page; however, you need to determine whether they apply. Bobby Approval requires that none of them apply to your page. Please review these 4 item(s):

  1. If you use color to convey information, make sure the information is also represented another way.

  2. For tables not used for layout (for example, a spreadsheet), identify headers for the table rows and columns. (15 instances)
    Line 456, Line 1017, Line 1108, Line 1363, Line 1632, Line 1785, Line 1858, Line 2106, Line 2323, Line 2535, Line 2697, Line 2765, Line 2998, Line 3121, Line 3292
  3. If a table has two or more rows or columns that serve as headers, use structural markup to identify their hierarchy and relationship. (15 instances)
    Line 456, Line 1017, Line 1108, Line 1363, Line 1632, Line 1785, Line 1858, Line 2106, Line 2323, Line 2535, Line 2697, Line 2765, Line 2998, Line 3121, Line 3292
  4. If an image conveys important information beyond what is its alternative text, provide an extended description. (14 instances)
    Line 989, Line 2808, Line 2815, Line 2822, Line 2863, Line 2882, Line 2907, Line 2945, Line 2976, Line 3610, Line 3618, Line 3654, Line 3695, Line 3729

The following 4 item(s) are not triggered by any specific feature on your page, but are still important for accessibility and are required for Bobby Approved status.

  1. Ensure that descriptions of dynamic content are updated with changes in content.

  2. Use the simplest and most straightforward language that is possible.

  3. Avoid ASCII art.

  4. If you can't make a page accessible, construct an alternate accessible version.

If the Priority 1 issues listed do not apply to your page, then it qualifies as Bobby Approved and you are entitled to use the Bobby Approved icon. To obtain the icon and learn how to place it in your page, visit the Icon Guidelines page on the CAST web site.

Bobby Approved status is assigned on the basis of Priority 1 items in the Web Content Guidelines. For a higher level of accessibility you may also want to examine Priority 2 and Priority 3 items. 2 Priority 2 issue(s) that Bobby has identified are presented below.

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.
