15 new teachers were introduced to the Knoxville School District in an orientation session in Knoxville yesterday. The large amount of new faces come after multiple teachers took early retirement incentives last spring. The school district used that retirement incentive program to save money. School begins today in the Twin Cedars school district. Knoxville, Melcher-Dallas, Pella, and Pella Christian begin school on Monday. Pleasantville and PCM start school next Wednesday.
