Some teachers in 46 Tennessee districts will see a pay boost next year after the State Board of Education voted Wednesday to raise the minimum salary for educators across the state.

The unanimous vote raises the minimum pay from $32,445 to $33,745, or an increase of 4 percent. The minimum salary is the lowest that a district can pay its teachers, and usually applies to new educators.

The boost under the new schedule won’t affect most Tennessee districts, including the largest ones in Memphis, Nashville, Knoxville and Chattanooga — where teacher salaries already exceed the state minimum. (You can see the list of districts impacted here.)

The state’s largest teachers union lauded the increase, which will be funded under the state’s 2017-18 budget under Gov. Bill Haslam.

“Teachers statewide are increasingly struggling to support their own families on the stagnant wages of a public school teacher,” said Barbara Gray, president of the Tennessee Education Association. “It is unacceptable for teachers to have to choose between the profession they love and their ability to keep the lights on at home or send their own children to college.”

Tennessee is one of 17 states that use salary schedules to dictate minimum teacher pay, according to a 2016 analysis by the Education Commission of the States. In that analysis, Tennessee ranked 10th out of 17 on starting pay.

The 4 percent raise is a step toward addressing a nationwide issue: the widening gap in teacher wages. On average, teachers earn just 77 percent of what other college graduates earn, according to a 2016 study from the Economic Policy Institute. Tennessee ranks 40th in that study, with its teachers earning 70 percent in comparison to other graduates.
