Some parents have removed their kids from Sunnydale Elementary School in Lancaster over possible mold contamination.
The Los Angeles County Department of Public Health sent a team of four people to the school on Monday. The group did a walkthrough of four classes with the school's principal, Brent Simpson.
Simpson says inspectors will return to campus for a more extensive review.
PTA President Karaleigh Roe sent photos of classes in disrepair and the alleged contamination to administrators and county health officials in February.
Simpson did acknowledge the pictures were of the campus.
The health department has admitted it dropped the ball on Roe's original inspection request, but moved quickly once officials realized the mistake.
Lancaster School District has run independent mold tests on about three-fourths of the classes on campus, all of which have come back clean.
Roe had her own test done. That one resulted in multiple levels of mold.
School officials say county inspectors will be able to decide if any work needs to be done at the school.
