Paying more goes hand and hand with testing teacher (or holding them responsible for students grades), and generally that's not very well received by teacher unions.
The example I always drop is my ap calculus teacher whose students had an average test score of a 4.7, but the ap physics teacher didn't have a single student get a 5. They never shared their average for obvious reasons, but I'd assume it was closer to the national average of 2.3 based on what I heard.
Clearly the school had students capable of putting in the effort, if the teacher was capable of teaching the material.
