Under Governor Susana Martinez and Education Secretary Hanna Skandera, New Mexico overhauled its teacher evaluation system. The state’s new NMTEACH system has been especially effective at differentiating teachers by the skillfulness of their work, with only 71 percent of teachers rated effective or better. In a study of 24 states, researchers Matthew Kraft and Allison Gilmour demonstrated that NMTEACH rated 28.7 percent of teachers ineffective—more than twice as many as the next closest state in the nation, Oregon.
