Wednesday was the first day that mask-wearing was required again for all Passaic School District employees, students and visitors.

"Please be advised that as per our Board Policy No. 5141.10, during periods of a High Activity Level as published in the NJDOH COVID-19 Activity Level Report, mask wearing is required," Superintendent Sandra Diodonet wrote in a letter to parents.

A seven-day average for confirmed positive tests shows that current case numbers are up 43% from one month ago.

Masks must now be worn in all district facilities, school grounds and buses. The mandate impacts every level of education, including Pre-K through grade 12 students.

Diodonet says the district will monitor COVID-19 activity in the city and lift the mandate when Passaic County is at a moderate or below range.
