Software Applications & Operating System Products
- Section 508 - Software Standards
- Accessibility Testing Techniques
- Vendor Specific Accessibility Sites
- Other Government Accessibility Web sites
This section contains resources for developers who are creating, maintaining or modifying software or operating systems products that must comply with the Section 508 Standards.
Section 508 Standards for Software vs. W3C Accessibility Standards
The World Wide Web Consortium (W3C) accessibility standards do not match the Section 508 Standards exactly. The Section 508 Standards are more narrowly defined than the W3C's. Many web development tools so be sure you are familiar with the Section 508 Standards for Software Products.
It is important to remember that good accessibility depends on good code. Clean, valid code is a basic assumption necessary for ensuring accessibility.

WebAIM has put together 4 simulations that allow you to see what users with various disabilities may experience when using assistive technology or simply interacting with a computer interface.
- WebAIM Screen Reader Simulation - This simulation provides a way to experience what it is like to use a screen reader. A Web site, the University of the Antarctic, is presented as a screen reader user would experience it. Keyboard shortcuts are provided to navigate within the site and find specific pieces of information.
- WebAIM Low Vision Simulation
- WebAIM Dyslexia Simulation - A sample of a timed reading exercise. It was designed to give users an idea of the frustrations a person with dyslexia could experience while using the web.
- WebAIM Distractibility Simulation - This simulation demonstrates how difficult it can be to navigate even a simple site when operating under an intense cognitive load as someone with a cognitive disability might experience.
