Accessibility is always a key concern for those offering online courses. This takes it head-on! All the resources used provide very clear guidelines. More than this the organization of the materials is quite user friendly. I completed a Master's degree several years ago in online course design and delivery. This would have been a very useful resource in that program---and this Web resource speaks to the areas of most concern, for instructors, and is current in its approach.
I found everything easy to navigate and accessible!
