The Disability Office (DSO) is required to keep information regarding a student's disability confidential. Even when a student identifies him or herself to disabilities, that information cannot be shared without the student's permission. This means that if a student has not disclosed his or her disability, we can't discuss it with anyone either, or even verify that it exists.
The need to share information with faculty and staff will vary depending on what the student is seeking. It is only when the student is requesting something out of the ordinary -- testing accommodations, for example -- that others need to become aware that a disability exists. In all cases, the student must provide disabilities with documentation from a professional that verifies the need for the service being requested.
