Students, faculty and staff will be required to wear masks in campus buildings this fall, head of academic planning Art Markman said in an interview with The Daily Texan on Friday.

Masks will be encouraged in outdoor spaces on campus, but not required, said Markman, a psychology professor.

Exceptions to the mask policy include staff members alone in an office and taking a break while maintaining social distancing, Markman said. Professors will be able to end class if a student is not wearing a mask, and any student, faculty or staff member who does not obey the mask policy will be subject to disciplinary procedures, he said.

Markman said wearing a mask is “probably the single most important thing” people can do to help keep others safe on campus.

On Wednesday, Interim UT President Jay Hartzell announced up to 2,100 of the 11,000 classes offered this fall will be held online. Last month, Outgoing President Gregory Fenves announced fall classes will be held on-campus beginning August 26 as planned but will end at the start of Thanksgiving break.
