Not by test outcomes, that's for sure. There's only so much a teacher can do when handed a classroom full of yard apes. My old man was high school biology teacher for over 30 years and his on the ground experience was that merit based pay didn't really work, so take that for what it's worth.

A lot of the hurdles classroom teachers have come from higher up the bureaucracy fucking with them. Stuff like adding more students into a class than is allowed or fucking with schedules and lesson prep materials without notice. It's not just the teachers that need to get sorted, it's the whole bloody system from top to bottom that is dysfunctional.
