Murray, KY – The Calloway County School District is undergoing its first district-wide accreditation evaluation. Public Relations Coordinator David Dowdy says in the past Calloway has done school by school evaluations, but these have not included the preschool. Officials hope district-wide accreditation will help them develop a better strategy for educating the county's children. Dowdy says an accreditation team began visiting the district Monday. They will present their report to the board tomorrow.
