At least 10 New Jersey colleges have implemented campus mask mandates regardless of COVID-19 vaccination status.

Princeton, Rider, Stockton and the College of New Jersey are the most recent schools to  require masks to be worn in public areas as students and staff begin returning to campus.

Most New Jersey counties are at the substantial or high level of community transmission. Under CDC guidelines it is recommended everyone wear a mask indoors in public settings.

TCNJ president Kathryn A. Foster on Thursday noted the number of COVID-19 cases nationwide has doubled to over 118,000 a day with over 1,300 new cases in New Jersey as of Wednesday. Students who have been granted an exemption required to take a COVID-19 test twice a week.

"Let me emphasize that the enhanced masking requirement and other measures are temporary. We will continually monitor case metrics and will amend these new restrictions once case numbers and transmissibility fall to safer level," Foster said. "We are heartened by data from Europe and other U.S. states that show rapid declines in case rates after a spike."

No school has canceled their plans to reopen campus fully.

"This fight is not over. Better days are ahead. But they are not here yet. Please continue to do your part. Do not let your guard down. Do not fall victim to pandemic fatigue," Seton Hall says on its website.

"Kean University requires all unvaccinated people to wear masks indoors on campus and encourages those who are vaccinated to wear a mask indoors when they feel it is necessary to help protect their health and the health of the entire campus community," spokeswoman Margaret McCorry told New Jersey 101.5. "The university will continue to monitor guidance from state and federal health officials and will respond to any changing circumstances as needed."

The mandate that started August 4 is only temporary at Monmouth University and is scheduled to end on September 1 but could be extended.

Exceptions will be announced for all sports and performing arts students.

Rowan University

Students who have provided proof of vaccination are not required to mask up but noted the CDC's recommendation about indoor public places. Unvaccinated students and staff must wear a mask at all times and must be tested weekly starting September 1.

Stockton University

Beginning Monday everyone must wear a mask indoors in all areas of campus. Guidance on residence halls are coming. The mandate will include classrooms beginning September 7.
