A "person with a disability" is "any person who (i) has a physical or mental impairment, which substantially limits one or more of such person's major life activities; (ii) has a record of such an impairment; or (iii) is regarded as having such an impairment."
A "qualified person with a disability" is one who meets the academic and technical standards required for admission to or participation in a postsecondary institution's programs and activities. Section 504 regulations and court cases interpreting Section 504 have identified the following physical and mental impairments:
A diagnosis of impairment alone, however, does not establish that an individual has a disability within the meaning of Section 504. Rather, to be protected by the law, the individual must, due to the impairment's current, past or perceived effect on a major life activity, meet the definition of person with a disability as described above.
