Karns Elementary School had a special addition in its morning drop-off line on Thursday.
Superintendent Dr. Jim McIntyre surprised teacher Beth Caballero by taking over for her on morning bus duty.
This 4th grade teacher says she appreciates the relief!
"It shows how much he really does realize all the things that we're doing from bus duty to teaching, this is a great surprise. It's a great help for me. I can go and enjoy my morning," said Caballero with a laugh.
The surprise bus duty relief was part of "Thank a Teacher" week in Knox County Schools.
