Do faculty have access to my records and know about my personal situation?

No.  Faculty do not have access to personal records and only know that you are registered with the DSS office when you provide them with an Accommodation Letter from DSS. The student, if registered with DSS and after providing documentation that DSS determines supports the accommodation, is provided with a letter that details the required accommodations to which they are entitled so long as they do not fundamentally alter an essential component of the course. For every student registered with DSS, the office has a file with documentation of the disability. For reasons of confidentiality, the nature and specifics of the disability are not disclosed to faculty.
