Section 508 Refresh
On January 18, 2017, the Access Board published a final rule that jointly updates the requirements for information and communication technology (ICT) covered by Section 508 of the Rehabilitation Act and Section 255 of the Communication Act. The refresh harmonizes these requirements with guidelines and standards in the U.S. and abroad, including standards issued by the European Commission and with the Web Content Accessibility Guidelines (WCAG), a globally recognized voluntary consensus standard for web content and ICT.
This final rule is effective March 20, 2017. [Note: The Board changed the effective date to March 21, 2017, as indicated in a notice published on March 2, 2017.] However, compliance with the new section 508-based standards is required beginning January 18, 2018.
Safe Harbor Provision
The final rule contains a Safe Harbor Provision that states "legacy ICT that complies with the existing 508 Standards and has not been altered after the compliance date (i.e., one year after publication of the final rule) need not be modified or upgraded to conform to the Revised 508 Standards. However, when existing ICT is altered after the compliance date, such alterations must comply with the Revised 508 Standards." The provision allows for micro-compliance; which is compliance limited only to the elements updated on a page.
Update to Section 255 of the Telecommunications Act
Section 255 is the FCC's set of accessibility regulations for telecommunication equipment manufacturers and service providers. The previous update to section 255 occurred in 2000. The goal of the 255 refresh was to align the regulations with the reality of 21st century telecommunications technology - the smartphone and mobile technology in particular. Not only is telecommunication hardware subject to 255 regulations, but software that is integral to the device - for example, the contacts and phone dialing apps that come pre-loaded on smartphones - must also be compliant with section 255.
Comparing WCAG 2.0 to Original Section 508
The Section 508 Refresh incorporates WCAG 2.0, Level AA standard by inclusion. Below is a table that indicates whether newly incorporated WCAG standards are substantially equivalent to prior Section 508 requirements, or if they are new criteria that now must be considered.

Did you know?
- In the United States, about 55 million people have a disability (src: 2010 U.S. Census).
- About 1 in 5 Americans have some kind of disability (src: 2010 U.S. Census).
- The percentage of people affected by disabilities is growing as our population ages.
- Two popular, free screen readers are VoiceOver (Mac OS and iOS) and NVDA (Win).
- Good accessibility practices can improve the search ranking of your website.
- Form fields without labels can cause problems for some assistive technology users.
- Low color contrast makes content difficult to see, especially for users with low vision.
- Documents linked on a website need to be accessible too (e.g., PDF and Word files).
- Audio content, like podcasts, need transcripts for deaf or hard of hearing users.
- Online videos should be captioned for deaf or hard of hearing users.
- Using HTML tags correctly is very important for accessibility.
- Descriptive link text helps make a website more accessible. Avoid using "Click here" or "Read more."
- A "screen reader" is an application that reads content aloud to a user.
- There is no "alt tag" in HTML. "Alt" is an attribute used with the img tag.
- HTML uses the alt attribute to provide a text description of an image.
- Alt text should describe an image, if the purpose of the image is to convey information.
- If an image is a link, the alt text for the image should explain where the link goes.
- If an image is only being used for decoration, the alt text should be null (i.e., alt="").
- If a table has headers, using header tags (<th>) will make the table more accessible.
- An accessible website is one that can be navigated and understood by everyone.
