Access to information by all
constituents of the UW-La Crosse community is inherent in our mission as an
institution of higher education. The World Wide Web provides a unique way to
deliver many of the university’s information resources. However, it is
important to consider that the design of these resources be accessible to all
members of our community, including those persons with disabilities.
In December 2000, a memo was sent
to all UW-System Chief Information Officers from Ed Meachen, Associate Vice
President at UW-System for Information Technology. The memo requested, on
behalf of President Lyall of UW-System, that all universities adopt a minimum
set of web accessibility guidelines and incorporate into their IT plan an
explanation of how they intend to assure that their web materials are accessible
to all consumers. To this end, in October 2001, John Tillman, CIO at UW-La
Crosse, appointed the Universal Access to Information Technology Resources
working group, chaired by Janice Ward, Manager, ITS Support Services. The
working group includes the following members: Al Thompson, Gail Kettner, Mary
Christie, Larry Sleznikow, Dave Faulkner, Heath Ahnen, Karin Bast, Joan Temple, Jen
Holman and Gary Johansen. Based on President
Lyall’s charge, the working group wrote this Web Accessibility Policy for the
University of Wisconsin-La Crosse.
This policy outlines the web
accessibility guidelines of UW-La Crosse. They have been established to ensure
accessibility and meet the ethical and legal obligations under the Americans
with Disabilities Act, the Telecommunications Act of 1996, and the
Rehabilitation Act of 1973, Sections 504 and 508 as amended. This document
provides a set of guidelines for the development of web-based resources, which
represent the University of Wisconsin-La Crosse.
UW-La Crosse web sites must
comply with the relevant subsections of Section 508 of the Rehabilitation Act of
1973, as amended. Specifically, UW-La Crosse will maintain compliance with
subsections 1194.1 through 1194.22 of Section 508. Additionally, UW-La Crosse
embraces the World Wide Web Consortium (W3C) guidelines and makes several
additional recommendations based on these guidelines. Details of the required
and recommended guidelines are described in Appendix A of this policy.
In addition to the Section 508
requirements, each UW-La Crosse web page must contain contact information for
users having trouble accessing the content. See Appendix A, Item No. 17, for
guidelines regarding contact information.
All University of Wisconsin-La
Crosse web sites must comply with the required guidelines according to the
timetable defined within this policy. This includes pages representing any
UW-La Crosse program, unit, department, division, or organization (including
individual faculty members and student organizations) whether housed on the main
university web server or elsewhere.
Each division is responsible for
the implementation of this policy. To assist divisions with implementation,
Information Technology Services (ITS) will work with appointed division
representatives to develop an implementation process for existing website
materials, make web site/page monitoring tools available and provide appropriate
web accessibility training. It is expected that the university’s existing web
site/pages will be compliant by December 31, 2003.
n addition to the schedule for
revision of existing pages, all new and redesigned pages posted after the
effective date of this policy must also comply with required guidelines. Any
non-compliant page for which a request for access is made must be revised in a
timely manner in accordance with Section 508 guidelines or the content must be
made available in alternative format.
Each UW-L program, unit,
department, division, or organizations has the responsibility to monitor the
continued accessibility compliance of its web sites/pages. We strongly
recommend using the tools recommended and supported by UW-La Crosse Information
Technology Services to aid in meeting this requirement[1]
.
ITS will conduct periodic reviews
of web sites. Designated contacts of non-conforming pages will be notified of
the guidelines and the resources available to assist them with meeting these
guidelines.[2]
A timely response to correct identified problems will be expected in order to
maintain compliance with this policy. Formal complaints regarding web page
accessibility issues will be handled according to current University procedures,
including if necessary, the removal of offending pages from the University web.
A key component to the successful
implementation of the Web Accessibility Policy will be the training and support
for web developers across campus. To that end, the
ITS Support Center in
cooperation with other University departments will offer training classes,
support documentation and resources, and consultations to web developers of
University web sites.
As guidelines and technologies
related to web accessibility evolve, this policy will be revised accordingly.
As such, it will be the responsibility of the University’s Chief Information
Officer (CIO), to request that a committee revisit and revise this policy as
needed.
The following guidelines represent the required items as
specified by Section 508 of the Rehabilitation Act, as amended, along with
additional recommended guidelines based on the World Wide Web Consortium (W3C)
web accessibility guidelines.
A web site will be in compliance with 508 standards if it meets
paragraphs (a) through (p) of Section 1194.22. Each required guideline appears
in bold type and compliance is required in order to meet accessibility
requirements. A brief description of each required guideline is also
provided. Descriptions have been adapted from the The Access Board, an
independent federal agency dealing with accessibility for people with
disabilities. Additional recommendations for optimal accessibility appear with
their related required guideline. This document is not intended to serve as
complete training on how to fulfill these guidelines. It is recommended that
all web developers receive training on the web accessibility guidelines in order
to fully understand each requirement.
Required – A text equivalent means adding words to
represent the purpose of a non-text element. This provision requires that when
an image indicates a navigational action such as "move to the next screen" or
"go back to the top of the page," the image must be accompanied by actual text
that states the purpose of the image. This provision also requires that when an
image is used to represent page content, the image must have a text description
accompanying it that explains the meaning of the image.
The number one issue with visually impaired persons accessing
web pages has to do with content conveyed by images that is not contained
elsewhere on the page. Use ALT attributes in the image reference anchors and
include descriptive text within the anchor. When creating alternative text, aim
for a functional label based on the context in which it is used rather than a
visual description. If alternate text is not necessary because descriptive text
is already provided above or below the image, use ALT=”” in the IMG tag. Many
web publishing tools such as Microsoft®
FrontPage® and
Macromedia® Dreamweaver®
have easy interfaces to add ALT tags to images. Learning to properly use these
tools when a graphic is inserted in the page will make it easy to add
alternative text.
Required – Captioning for the audio portion and audio
description of visual information of multimedia presentations are considered
equivalent alternatives. This provision requires that when an audio portion of a
multimedia production is captioned, as required in provision (a), the captioning
must be synchronized with the audio. Synchronized captioning is required so that
someone reading the captions can also watch the speaker and associate relevant
body language with the speech.
If information presented is audio-only, a transcript of the
audio must be available in order to satisfy item (a) for a text equivalent of a
non-text element.
Required - When colors are used as the sole method for
identifying screen elements or controls, persons who are color blind as well as
those people who are blind or have low vision may find the web page unusable.
For example, when a web page directs a person to push the green button to start,
the button should also be identified in some other fashion besides green.
Required – Style sheets can enable users to define
specific viewing preferences to accommodate their disability. It is critical
that designers ensure that their web pages do not interfere with user-defined
style sheets. When using Cascading Style Sheets (CSS), be sure that the
document is still readable when CSS is turned off or a personal CSS is used.
For example, if you color code certain words using CSS, the colors will be lost
in text-only browsers or screen readers.
Recommended –
-
Use headings (<H1>, <H2>, etc), lists, and consistent
structure to keep the document organized.
-
Minimize the time it takes the web page to load.
Required - When a web page uses a server-side image map
to present the user with a selection of options, browsers cannot indicate to the
user the URL that will be followed when a region of the map is activated.
Therefore, a redundant text link is necessary to provide access to the page for
anyone not able to see or accurately click on the map. It is preferable to
avoid server-side image maps in most cases.
Required - Unlike server-side image maps, the client-side
image map allows an author to assign text to each image map “hot spot.” This
feature means that someone using a screen reader can easily identify and
activate regions of the map.
Recommended –
Required – When a table is used in a web site to provide
data, appropriate markup for row and column headers is required. Large tables
of data can be difficult to interpret if a person is using a non-visual means of
accessing the web. Users of screen readers can easily get "lost" inside a table
because it may be impossible to associate a particular cell that a screen reader
is reading with the corresponding column headings and row names.
Required – When a table displaying data contains two or
more levels of headers (see example below), appropriate markup must also be used
to associate the data cells and headers cells correctly.

Recommended – Summarize tables for clarity. The
“Summary” attribute of the Table tag may be used although some assistive
technology devices do not support the “Summary” attribute. Consider placing
their descriptions either adjacent to their tables or in the body of the table,
using such tags as the CAPTION tag. In no event should web developers use
summarizing tables as an alternative to making the contents of their tables
compliant as described above.
Required – Use frames cautiously, always providing
NOFRAMES content and giving titles to each frame. (Remember to keep your
NOFRAMES content up-to date.) Each FRAME must reference an HTML file.
Recommended – Consider designing a page without frames.
Frames provide a means of visually dividing the computer screen into distinct
areas that can be separately rewritten. Unfortunately, frames can also present
difficulties for users with disabilities when those frames are not easily
identifiable to assistive technology. For instance, a popular use of frames is
to create "navigational bars" in a fixed position on the screen and have the
content of the web site retrievable by activating one of those navigational
buttons. The new content is displayed in another area of the screen. Because the
navigational bar doesn't change, it provides a stable "frame-of-reference" for
users and makes navigation much easier. However, users with disabilities may
become lost if the differences between the two frames are not clearly
established.
Required - Some individuals with photosensitive epilepsy
can have a seizure triggered by displays that flicker, flash, or blink,
particularly if the flash has a high intensity and is within certain frequency
ranges. Flashing or flickering elements are usually added through technologies
such as animated gif's, Java applets, or third-party plug-ins or applications.
Required – Creating a text-only page for your content is
considered a last resort in creating accessible web pages. When creating a
text-only page, it must be updated whenever the primary page changes and an
accessible link to the text-only page created from the primary page.
Required - Web page authors have a responsibility to
provide script information in a fashion that can be read by assistive
technology. When authors do not put functional text with a script, a screen
reader will often read the content of the script itself in a meaningless jumble
of numbers and letters. When using script (such as JavaScript), it is important
that web page developers learn how to write accessible code.
Required- This provision requires that web pages that
provide content such as Real Audio or PDF (Adobe Acrobat's Portable Document
Format) files also provide a link to a plug-in that will meet the Section 508
guidelines for accessible software. This provision places a responsibility on
the web page author to know that a compliant application exists, before
requiring a plug-in. Plug-ins or applets that require the use of non-accessible
software should not be used.
Required – When using online forms, the web developer
must use <LABEL> and <ID> tags to ensure that the label of a field is correctly
associated with its field element. For instance, if an input box is intended
for receiving a user's last name, the web developer must be careful that the
words "last name" (or some similar text) appear near that input box or are
somehow associated with it. However, the visual proximity of a form element and
its title offers no guarantee that a screen reader will associate the two or
that this association will be obvious to a user of assistive technology. Use of
the <LABEL> and <ID> tags will ensure the relationship between these elements.
Explicit labeling works extremely well with all popular assistive technology.
Required - This provision provides a method to facilitate
the easy tracking of page content that provides users of assistive technology
the option to skip repetitive navigation links. Web developers routinely place a
host of routine navigational links at a standard location – often across the
top, bottom, or side of a page. For those who use screen readers or other types
of assistive technologies, it can be a tedious and time-consuming chore to wait
for the assistive technology to work through and announce each of the standard
navigational links before getting to the intended location. In order to
alleviate this problem, the section 508 rule requires that when repetitive
navigational links are used, there must be a mechanism for users to skip
repetitive navigational links.
Recommended – Make text links descriptive but not overly
wordy. Your text descriptors need to convey information about the nature and
destination of the link. For example, authors should not use “click here” as a
link.
Required - Web pages can be designed with scripts so that
the web page disappears or "expires" if a response is not received within a
specified amount of time. Sometimes, this technique is used for security reasons
or to reduce the demands on the computer serving the web pages. Someone's
disability can have a direct impact on the speed with which he or she can read,
move around, or fill in a web form. For this reason, when a timed response is
required, the user shall be alerted via a prompt and given sufficient time to
indicate whether additional time is needed.
Required – Each UW-L web page shall have an email address
and phone number as a contact for assistance. This contact shall be a full-time
University staff person within the relevant program, unit, department, division,
or organization who is either the web page developer or who is able to work with
the developer to correct the problem and address the needs of the user. Contact
information shall be clearly identified as such on each web page.

The Universal Access to Information Technology Resources Committee is
currently evaluating such tools and will publish a list of recommended and
supported utilities through the
ITS Support Center.

The ability to conduct such reviews and monitor progress of the University
is dependent upon the University’s ability to acquire a product to assist in
web-wide review. Such products are currently under evaluation by the
Universal Access to Information Technology Resources Committee.
