The Consistency of Composite Ratings of Teacher Effectiveness: Evidence From New Mexico
We estimate the consistency of composite ratings of teacher quality from New Mexico's teacher evaluation system from 2015 to 2016.
Student performance reflects many factors beyond their teacher's effectiveness, yet teacher evaluations often reflect how well their students do on standardized tests. RAND researchers are nationally recognized for their work using value-added modeling to distinguish a teacher's impact from factors such as individual ability, family environment, past schooling, and peer influence.
