Masks are top of mind these days but some parents are starting to question other policies and procedures schools are using to keep students safe.
From Mansfield to McKinney, parents have butted heads over whether masks should be required for all students in school.
While it's become a national debate, mother Leslie Williams has had other worries in the classroom.
"The school district does need to sit down and look at the numbers and figure out why we had 20 positives in one day," she said.

Williams is a professional contact tracer, tracking cases daily for a medical company. Yes, she wants masks required in the classroom but says she's been more worried about contact tracing in school. She says it's a huge job that school nurses just aren't capable of doing.
"I had a case that had 450 contacts," said Williams. "They need to get with a third party company and do actual tracing or let the nurses tell the teachers."
Williams also raised questions about the cleanliness of schools and the amount of sanitizing being done on campus.
