NGC Accessibility Statement
(Americans with Disabilities Act Section 508)
The National Guideline Clearinghouse™ (NGC™), sponsored by the
Agency for Healthcare Research and Quality (AHRQ), U.S. Department of Health and
Human Services, has been designed specifically with accessibility in mind.
All pages are checked with
Bobby,
the Web page analysis tool, to ensure compliance with both the
W3C accessibility guidelines and the
Americans with Disabilities Act (ADA) Section 508 requirements.
Access keys
Most browsers support jumping to specific links by typing keys defined
on the web site. On Windows, you can press ALT + an
access key (Internet Explorer only brings focus to the link. You must hit Enter to activate the link);
on Macintosh, you can press Control + an access key.
The access keys for the NGC site are defined to follow the
recommended access keys standard as implemented by UK Government Websites.

Navigation Aids
- All pages have additional links to aid navigation in text-only browsers and
screen readers. Netscape 6 and Mozilla users can also take
advantage of this feature by selecting the View menu, Show/Hide,
Site Navigation Bar, Show Only As Needed (or Show Always).
- Tables are coded to meet all Priority 1 WAI checkpoints. These tables
properly associate the data with its header and provide additional accessibility
features, such as summary attributes.
- The NGC website includes a search box (access key 4).
Links
- Many links have title attributes which describe the link in greater
detail, unless the text of the link already fully describes the target.
- Whever possible, links are written to make sense out of context.
Many browsers (such as JAWS, Home Page Reader, Lynx, and Opera) can
extract the list of links on a page and allow the user to browse
the list, separately from the page.
- Link text is never duplicated; two links with the same link text
always point to the same address.
- There are no "
javascript:" pseudo-links.
All links can be followed in any browser, even if scripting is
turned off.
- There are no links that open pop-up windows without warning.
Images
- All content images used in the home page and all archives include
descriptive ALT attributes.
Purely decorative graphics include null ALT attributes.
- Complex images include LONGDESC attributes
and links to text-only descriptions to explain each image to non-visual readers.
Visual design
This site and all its archives use cascading style sheets for visual layout.
- The default stylesheet uses only relative font sizes, compatible
with the user-specified "text size" option in visual
browsers. For example, if you're using Internet Explorer, you
can make your default text size larger under the "View"
menu, "Text Size", "Larger" (or "Largest").
- A print stylesheet is used to eliminate the need for an additional
print page, or a "text-only" version.
- If your browser or browsing device does not support stylesheets at
all, the content of each page is still readable.
