Studies show that students with the best teachers learn three times as much as students with the worst teachers.

Teachers matter. A lot. Studies show that students with the best teachers learn three times as much as students with the worst teachers.

Politicians and education reformers are calling for big changes in how teachers are trained and evaluated – and in the way teachers are hired and fired too.
