• Section 508 is the name of the amendment to the Rehabilitation act of 1973 that requires Federal agencies to make their electronic and information accessible to people with disabilities (U.S. Access Board, 2010).

• Section 508 requires that when Federal agencies develop, procure, maintain, or use Electronic and Information Technology (EIT), they shall ensure it is accessible to people with disabilities (U.S. Access Board, 2010).

• Hyperlinks (URL’s) and active links need to display a fully qualified URL - i.e. http://www.samhsa.gov and not www.samhsa.gov.

• Right click on link text and select “Edit Hyperlink”, then enter fully qualified URL.

6HHS PowerPoint Document 508 Checklist (1.3)


• It is important that the list of links makes sense to the user when it is read out of context.

• Each link should make sense in the list when it is read in isolation.

7


• Avoid using flickering/flashing text and/or animated text.

• Provide an alternate, non animated slide for the content.

12


Well-written alt text should convey the same “take home message” as the image.

13


Text equivalents are present, but they are insufficient. Consequently, users accessing the information via screen readers will not have the same level of access that sighted users do.



• The name of the Image (madura_c12eQ2b.jpg) should not be used as an Alternative Text.

• An option to remediate this image will be to have a link to an Accessible table.

15Required by Section 508 Standard 1194.22(K)



An option is to have the Organizational Chart linked to an HTML page.

Have all multi-layered objects been flattened into one image and has one Alternative Text (Alt Text) been provided for this image?


Does a contrast ratio of at least 4.5:1 exist between text, or images of text, and background behind the text?

Ensure sufficient color contrast in text, charts, and images.

21


• Identify the Correct Way of Using Tables• Identify Accessible Tables• Identify Table Headers and Rows• Ensure Your Presentation is Keyboard

Accessible

22


• When non-tabular text is rendered with tables, the reading controls are incorrect.

• This can make it confusing and difficult to read the document with a Screen Reader.

HHS PowerPoint Document 508 Checklist ID (3.4)23


To determine whether tables have been used for visual formatting

Right click on any text that you suspect is formatted as a table. If the Table Tools part of the Ribbon shows up, table formatting has been used.

24


Someone who can read a table or chart visually can refer back to the column and row headings or the X and Y coordinates to make sense of the data.

25


• The screen reading software by default will read the information in a table horizontally, cell by cell, row by row.

• Tables are read efficiently by screen readers when the column or row headers are clearly defined.

26


• Identify that table columns have been assigned a header row.

• This enables the Screen Reader software to be able to tell the user for each cell what the header for that column is.

Required by Section 508 Standard 1194.22(g)27


1. Double Click the Table.

2. The Table Tools Design will open.

3. Go to the Table Style Options group and ensure the Header Row and/or First Column are selected in the check box.

Though it can be a complex process to check a PowerPoint Presentation for accessibility, when you identify and remediate documents, you also make them more portable. This means that they work better across all web-browsers, computer systems, and types of devices.

To Identify accessibility errors remember to:– Review Layout and Formatting– Review Image Requirement– Review Table Requirements
