The letter makes recommendations of universal masking for students and staff, minimize contacts for each student and encourage eligible students to get the COVID-19 vaccine.

“After reflecting on the data that was provided in that letter, data from Fort Worth, Texas, from Fort Worth ISD as well, and these data impact approximately 80,000 students and 10,000 employees, I have directed staff to implement a reopening of schools plan that is in accordance with CDC and American Academy of Pediatrics recommendations, which includes a mask mandate for all indoor school facilities and buses for students and employees,” Scribner said Tuesday.

“We will monitor our COVID data and revisit this protocol as appropriate,” he added.
