How do I know if a member of the Mason community has an accommodation to not wear a face mask/covering?

If a student has been approved not to wear a face mask (i.e., face shield, another alternative, or nothing) Disability Services will communicate this with faculty and staff members that directly work with the student (i.e., professor/instructor or any office or department they visit frequently), and the accommodation will be listed on the faculty contact sheet (accommodation letter). No one should make the determination that a student is not allowed in a class or space without consulting with Disability Services. See GMU university policy for more details: GMU Face Mask Policy.
