British Standards Institute's PAS 78

What is it?

PAS 78: Guide to good practice in commissioning accessible web sites, encompasses the information contained within the W3C Guidelines, the WAI Guidelines and the Disability Discrimination Act, and brings it together in a form that is easily understood.

It was produced by the BSI in conjuction with the Disability Rights Commission.

What does it mean for you?

It is aimed as much at the people responsible for the commissioning of a web site as those responsible for the design, development and testing.  All those involved have a duty and responsibility to make sure that a web site offers the maximum chance of accessibility for the majority of Internet users.

What does it cover?

The information covered can be grouped into six main areas:

  • The accessible web site process - guidance on building an accessible web site from commissioning and developing it, through to publishing and maintaining it. This also includes guidance on contracting web design and accessibility auditing services
  • Accessibility policy - its importance and how to define this for the web site
  • Web Accessibility Initiative (WAI) guidelines - their importance in the context of accessibility issues, what they mean and which ones to follow
  • Involvement of disabled people - in the requirements gathering, conceptual design and testing processes
  • Conformance checking - guidance on adhering to it
  • Additional accessibility provisions - elements additional to conformance to the WAI guidelines can be useful but should not be considered essential
