Disability-specific information may be helpful when you have a student with a disability in your class. It is important to remember that not all disabilities are obvious. When the disability is obvious, the question becomes, "What degree of accommodation and assistance is necessary?" Students who have non-apparent or non-obvious disabilities may choose not to mention his or her condition to the professor. For example, a student with epilepsy who is on medication, may not expect to require any adaptations or accommodations, and may not disclose their condition to you.
Because each student with a disability will have a different ability (even within the same disability category), the information presented here should be seen as general guides, not as specific instructions.
