People with disabilities -- visible and invisible -- are often viewed as a homogeneous group with similar needs and limitations. But at St. Mary's University, we believe that students with disabilities are as diverse as any other university population. The disability may be noticeable or not, congenital or the result of disease or injury, all of which can create minor inconveniences or formidable challenges to the student. St. Mary's is committed to providing an education in an environment that is both accommodating and nondiscriminating to all students, regardless of a disability. Who is Disabled? or what criteria are used to decide... Section 504 of the Rehabilitation Act of 1973 defines a person with a disability as anyone who: Has a physical or mental impairment that substantially limits one or more major life activities, Has a record of such impairments, Is regarded as having an impairment.
