General Resources

Web Accessibility in Mind (, or WebAIM, may be the best single introduction to online accessibility. It hosts an extensive collection of articles and how-tos on accessibility generally and on specific applications and file types. WebAIM also provides insight into how people with different kinds of disabilities access the web, including many simulations and videos.


If you like checklists, you might find these sites helpful:

  • This Quick Accessibility Checklist is meant to help faculty and staff who want to develop or modify Web-based course material, lectures, and assignments in an accessible way:
  • These Guidelines for Accessible Distance Education categorize strategies into musts, shoulds and mays for PDF, Excel, Flash, PowerPoint, Video and Word:

Online Courses and Tutorials

Online courses and tutorials covering web accessibility generally include:

  • A Section 508 Web Accessibility Tutorial includes sections on text alternatives, checking accessibility, navigation, image maps, audio and multimedia, color/flicker use, forms, tables, scripts and applets, style sheets, and 508 provisions:
  • The Access E-Learning tutorial, available via free registration, provides extensive information and practice labs on disabilities, creating an accessibility plan, PowerPoint, Video, Flash, Word, Excel, PDF, HTML and Scripts/Java:
  • “Web Accessibility 101” course is organized by 508 guidelines, and also includes information on evaluating for accessibility:
  • The New York State Forum's IT Accessibility Committee created an “Accessibility Curriculum” in 2005, also available online.
