All schools remain closed in a Cumberland County district while work continues to clean mold from the buildings.
The school superintendent says East Pennsboro Area Middle School, East Pennsboro Elementary and West Creek Hills Elementary will be closed until Tuesday.
Air quality tests found elevated levels of spores in the Middle School and West Creek Hills school.
They'll be cleaned over the weekend.
The first week back to school was thwarted after mold was found on ceiling tiles at the high school.
