Browse the Creating Accessible Teaching and Supports (CATS) website for downloadable information sheets about the effects of particular impairments, and teaching and assessment tips.
Keep in mind:
A student may have more than one area of disability, and the impacts on their study may be the result of a combination of impairments.
Students with the same impairment may experience different impacts and have quite different needs - this might depend on the extent of the impairment, the strategies the student has already developed, the student's educational experience and the nature and level of the course they are doing.
The best way to understand a particular student's needs is to talk with them.
Your focus is on the impact of the disability, not the diagnosis or the nature of the disability.
Students may experience long or short-term impairments, and their needs may vary over time.
