All students HAVE to complete the Daily Symptom Screener and be cleared with a green badge to access UC Berkeley campus. If an exam is scheduled in person in a campus building, the students are required to have a green badge valid for the day of the exam.
While it certainly may be good practice to remind students of that requirement, faculty are not authorized to verify compliance with that mandate. Currently, no one is authorized to ask to see someone else’s badge status except in health care settings and during Golden Bear Orientation check in. (https://coronavirus.berkeley.edu/campus-access/)
