Accessibility for Knowledge Management: Section 508 and WCAGEstimated Reading Time: 3 Minutes
One of the goals of knowledge management (KM) is to increase collaboration and to facilitate knowledge creation and sharing. Section 508 and WCAG plays an important role in making technology accessible to people with disabilities like deaf or hearing impaired, vision impaired, etc. To cater to the needs of people with disabilities, Section 508 and the Web Content Accessibility Guidelines (WCAG) will lend a helping hand in accessing the web-based knowledge content.
WCAG, ADA, and Section 508
WCAG (Web Content Accessibility Guidelines) are the guidelines with technical standards, to make web content handy in reaching out to disabled people. It has been conceptualized by W3C (World Wide Web Consortium) which is an international group supported by its own members and public, in developing and altering web standards.
The WCAG is categorized into three levels that resemble one another based on accessibility standards. The levels being A, AA, and AAA. Level A denotes the lowest accessible standards pertaining to web content similar to the rules in Section 508. In AA and AAA, the guidelines are more scrupulous which pave the way for further accessibility. While referring to level AA guidelines, it includes A and AA standards. Similarly, AAA includes guidelines of all the levels – A, AA, and AAA.
- WCAG A criteria which must be fulfilled, it’s the basic, standards are very similar to Section 508 rules
- WCAG AA criteria that should be compiled, comes with more rigorous guidelines that much improve the website’s accessibility
- WCAG AAA criteria that can be met, very high requirements, getting this compliance across the whole website is a complicated task
ADA and Section 508 cover WCAG guidelines that apply to the USA only.
ADA standards must be followed by all commercial and public entities that have "places of public accommodation” which includes the internet. ADA compliance is starting a huge issue in the USA. It is recommended to use the WCAG 2.0 level AA guidelines as a guide on how to become accessible.
Section 508 is an amendment to the Rehabilitation Act of 1973, which provides accessibility to disabled people in the electronic and information technology field through the U.S. Federal system. U.S. government websites and applications and those developed using US Federal funds must comply with Section 508.
Difference between WCAG, ADA, and Section 508
As Section 508 comes under U.S law, this law (the Rehabilitation Act of 1973) is applicable in the United States and it’s federal agency system. WCAG differs from Section 508 as it is not a law but guidelines that standardized internationally in making the web-based content reachable to people afflicted with disabilities. In a nutshell, WCAG is acceptable internationally pertaining to web-based content and its practices. In contrast, Section 508 adheres mainly to the U.S based entities relating to electronic and information technology.
The fine points that include in Section 508 and WCAG are listed below.
- WCAG 2.0 developed by W3C, a set of guidelines accepted internationally for web accessibility
- Different compliance levels – A, AA and AAA
- Applicable to the USA Only
- Applicable to United States electronic and information technology procured through the federal government
- It is a law which is applicable to all federal agencies and departments
- A set of standards applicable to various electronic communications

In conclusion, any organization, whether directly or indirectly funded by the government, should be compliant with Section 508 for creating their knowledge base content. Other countries follow WCAG norms for e-learning courses.
Due to some limitations like extra cost and effort, the non-government organizations are prevented from making accessibility a priority. Instead, they opt for having one-to-one sessions with the concerned individual.
