As a math teacher, I was well aware that my students had a yearly state-mandated standardized test, while most other teachers had no such tests. As discussion of using test scores for teacher evaluations increased, I assumed policymakers would realize that not everybody had scores and that would lead to problems. Enter the current craziness in Tennessee, where scores will be used to measure every teacher -- even if the students producing those scores aren't yours.
