Accessibility is "the usability of a product, service, environment or facility by people with the widest range of capabilities." -- ISO 9241-20 Ergonomics of human-system interaction.
This includes making products independently usable for people with disabilities, who might be using assistive technologies. It also benefits people, including yourself, who are using the products under less-than-optimal conditions.
If your site or service is used in programs and activities of the University, it has to be accessible. The Stanford University Online Accessibility Policy details the requirements and responsibilities of providing accessible Electronic and Information Technology (EIT).
Whether you are developing a custom Stanford application or purchasing a service from a vendor, you need to ensure that your site or service meets accessibility requirements.
Stanford has purchased accessibility services from Level Access (formerly SSB Bart Group) to help Stanford achieve its Accessibility goals. The suite of products available includes:
The Stanford Online Accessibility Program (SOAP) manages Stanford's AMP service, which is centrally funded by University IT and University Communications. The Stanford web development community also cost-shares a subscription to an alternative tool called SiteImprove, which provides better content-related features (such as Search Engine Optimization and spellchecking), but is less powerful in detecting Accessibility problems and providing guidance to address them. Contact SOAP if you are interested in cost-sharing/using SiteImprove.
