The school's health and safety plan dictates that masks will return until the number of people infected with coronavirus drops below 3%.
Whitehead said the school is working to address cafeteria spacing and other upcoming changes that will take effect on Friday.
"We will continue to monitor our numbers daily and send an addition communication once we are able to return to a mask recommended environment," Whitehead wrote.
