A while ago I wrote an article encouraging anyone commissioning a website to get hold of a publication by the Disability Rights Commission. ‘PAS 78: A Guide To Good Practice In Commissioning Accessible Websites’ is a comprehensive guide for anyone commissioning a website on what to look for and how to achieve compliance with the necessary laws.The great news is that this document is now free.
