Twenty Tennessee educators have earned a national certification that’s considered the profession’s highest mark of achievement, although the state continues to lag in the South in growing that community.

The state Department of Education on Tuesday released the list of new educators designated as National Board Certified Teachers.

Their addition brings Tennessee’s number of NBCT educators to more than 700, with another 63 pursuing certification. By comparison, Kentucky has 3,600, Virginia 3,400, and Georgia 2,600.

“We know that teachers are the biggest factor in the success of our students, and it is an honor to celebrate educators who are helping their students grow, while serving as an example of what it means to be a lifelong learner,” Commissioner Candice McQueen said in a statement.

Nationally, 5,470 teachers earned the designation in 2016-17, raising the total to more than 118,000 through the National Board for Professional Teaching Standards. The certification takes from one to three years to complete and includes a performance-based peer-review process. Successful candidates must demonstrate a proven impact on student learning and achievement.

In Tennessee, at least 36 school districts offer at least one type of incentive for achieving the certification. The most common is a salary bonus.

North Carolina continues to lead the nation in certification, with 616 more teachers gaining the endorsement last month from the Arlington, Va.-based organization.
