Accessibility Best Practices

 

What is Web Accessibility?

People all over the world use the web to find, utilize and share information. Web accessibility assures that the information and tools available on the web are accessible to and usable by everyone. When we make our websites accessible we ensure our content can be viewed by as wide an audience as possible. 

This audience is a diverse group with a vast range of skills, abilities, and technical equipment. Our website visitors use a variety of browsers, computers and devices, operating systems, and assistive devices. They come from a wide range of locations, educational backgrounds, web experiences, abilities, and skill levels.

According to the 2010 US Census1, 19% of the population has some type of disability. About 8.1 million people had difficulty seeing, and about 15.5 million adult had difficulties with one or more instrumental activities of daily living, including using a phone1.  Our users have the following characteristics:

  • Unable to see, have low vision, or are color blind. Users who are blind may depend on a keyboard to navigate a website, or may use a screen reader to convert text into speech. Users with low vision may not be able to see content that is small or has insufficient contrast. Colorblind users cannot perceive the difference between certain color combinations.
  • Unable to hear. Video and multimedia content is becoming more prevalent on the web. Those who cannot hear are at a disadvantage when captions and video transcripts are not provided. 
  • Have a motor or physical disability. Users with motor or physical disabilities often rely upon assistive technologies and devices to utilize computers and navigate the web. An accessible website works alongside technologies such screen readers, voice recognition software, and non-traditional mice to help users harness a computer’s functionality.
  • Have a cognitive impairment. Users with cognitive impairment may be challenged by visual and reading comprehension. By relying on predictable navigation patterns, uncomplicated layouts, and avoiding distracting design elements, we can help these users access our content with ease. 

By making our websites compliant we are providing equal access to information to all users, regardless of ability.

The University of Pennsylvania is committed to providing equal access to information, programs, and activities by making our web pages accessible to everyone, including people with disabilities2. We use the 1990 Americans with Disabilities Act, the 1973 Rehabilitation Act, and the W3C Web Content Accessibility Guidelines (WCAG 2.0) to determine compliance.

 

Web Accessibility Compliance

  • Section 504 of the 1973 Rehabilitation Act states that "no otherwise qualified individual with a disability in the United States shall be excluded from, denied the benefits of, or be subjected to discrimination under any program or activity that receives Federal financial assistance"3. This includes colleges and universities.
  • In 1998, Congress amended Section 508 of the 1973 Rehabilitation Act to "require Federal agencies to make their electronic and information technology (EIT) accessible to people with disabilities"4. While these standards apply to the federal government, they are the baseline to which many institutions comply.
  • Title III of the Americans with Disabilities Act covers privately-funded schools. All public or private schools that receive federal funding are required under Section 504 of the Rehabilitation Act to make their programs accessible to students with disabilities5.  
    • The Department of Justice is considering revising the regulations implementing Title III in order to establish requirements for making the goods, services, facilities, privileges, accommodations, or advantages offered by public accommodations via the internet accessible to individuals with disabilities.

  • In December 2008, the World Wide Web Consortium (W3C) developed the Web Content Accessibility Guidelines (WCAG) 2.0, which are "the basis of most web accessibility law in the world"6
