The first step in evaluating a web application for accessibility is to perform a visual review of the application. During the review, look for the following items: page structure, page title, skip nav link, color and position, and page readability.

An application that is keyboard-only accessible can be used with alternate input devices for people with limited mobility or an inability to manipulate a mouse. When people can use a keyboard, the internet is at their fingertips.

When using a screen reader with a web application, we use the term validation instead of the word test. There is a definitive answer with a test; validation imputes more than one right answer. The outcome of the validation changes slightly as the browser and screen-reader versions change.
