Many East Tennessee schools canceled or delayed classes on Friday because of the cold temperatures, but Knox County was not on the list.

We heard from a number of parents who were upset about that decision, and we asked Superintendent Dr. Jim McIntyre how he came to the decision to have classes as normal.

Statement from Dr. Jim McIntyre:

"The safety of our students and our staff is always the overriding factor in any decision we make about canceling or delaying school due to inclement weather. While it was very cold this morning, we made the careful determination that both our transportation systems and facilities would be prepared to serve our students on a regular schedule today.

This morning was clear and not as cold (especially considering wind chills) as it was two weeks ago when we closed school for inclement weather amid transportation and facilities issues caused by record low temperatures. Delaying school opening can sometimes cause disruption and confusion that might lead to the possibility of a student waiting longer for a bus in the cold. Again, these are decisions we take very seriously and make exclusively on the basis of safety considerations."

The school system also encouraged parents to "ensure their children are dressed appropriately for the weather."
