The University of Wyoming has changed its plans and will begin the fall semester on August 24 and will only have limited in-person classes beginning September 7.
All students will return for face-to-face instruction beginning towards the end of September.
University spokesman Chad Baldwin said rigorous testing is the best way to make sure students, faculty and staff are safe and officials wanted a little more time to make sure they were ready to go.
"We are not going to be fully operational with that rigorous testing until later in September."
Baldwin said the goal is to avoid any outbreaks that could cause a bigger disruption during the semester.
"But I can tell you that President (Ed) Seidel, the administration, and the board by virtue of their action feels very strongly that this revision now puts us in the very best place to be able to finish a successful semester," said Baldwin. "What we didn't want to have happen is get everybody here, then have an outbreak and have to send everyone home."
UW will return to online classes on November 23 after Thanksgiving break.
