The Tennessee Department of Education will give teachers with the state’s highest evaluation scores signing bonuses to teach in the state’s lowest-performing schools. The Tennessee Department of Education is offering districts across the state enough money to give each new teacher at a priority school a $7,000 signing bonus. In Knox County, one school is a priority school: Sarah Moore Greene Elementary, whose principal recently announced he would overhaul school staffing this year. But the state says only teachers who scored a level 5 in evaluation - the highest number possible - will be eligible for the bonus application process.
