Websites and web applications have the opportunity to provide additional information to persons with disabilities to help them understand and navigate more easily. Some of this information is visible to all users and can enhance their experience. Some of it is transparent to sighted users, but provides context for persons with visual, auditory or motor limitations.

In an accessibility markup (code) review, the focus of the inspection is not the interface as the user sees it, but an under-the-covers examination of the code used to implement it – often HTML.

The person conducting the review must be familiar with the implementation language and know what standards of quality and correctness apply. Code reviews are an important part of an accessibility assessment since there are a number of established conventions that must be followed.

Accessibility Review Protocols

The Fluid UX Accessibility Working Group has created a set of protocols for assessing accessibility. Code review is one aspect of an accessibility review.  If you'd like to do a deeper, more thorough evaluation, check out these additional resources.  These include inspecting markup as well as inspecting the behaviour of interfaces.

Another useful guide for determining whether a site addresses accessibility through properly crafted HTML is the IBM Human Ability and Accessibility Center: Web Accessibility Checklist.
