Oldham County schools welcomed students back to the classroom on Wednesday."My message to students is welcome back, we have missed you and we're glad you're here," said Beth Wallingford, the principal at Crestwood Elementary.On Wednesday morning, students were greeted with smiles and high fives as they trickled in from cars and buses into Crestwood. "This year, for elementary school, it's pretty much business as usual and getting back to basics and focusing on instruction and student learning and all of the great work that is happening in our classrooms every day," Wallingford said. In the classroom, teachers were busy making last-minute adjustments."I know that I'm nervous so seeing them really makes me not nervous anymore," said Kindergarten teacher Rachel Hirsch.Hirsch is in her fourth year teaching at Crestwood."The theme of our classroom is that this is a farmhouse and it's our home, so students know that this is where they feel welcome," Hirsch said.While elementary schools in Oldham County started on time, middle and high schools times were pushed back by 15 minutes due to a shortage of bus drivers. "We have approximately 75 bus routes and we are in need for about 22 drivers, so we're having to use officer staff and other staff to help cover those routes," said Oldham County Schools Superintendent Dr. Jason Radford.Radford says while it isn't ideal, it works for now as they work to hire more drivers. But like all schools, they're working with what they have currently and the teachers here are focused on making students transition back to school as smooth as possible."This is a lot of their first time in our building, so we always have a really big scavenger hunt to learn where all the different places are in our building and to meet our friend, Chester the raccoon," Hirsch said.Click this link for more information on how to become a bus driver for the district.
