In an ideal world we would have teachers A, B, and C in that order of teaching skill. The A teacher has to turn students away and raises tuition, the B teacher makes a living, and the C teacher finds a different job because he gets no students.
In an ideal world, teacher pay would be high enough to be able to attract sufficient numbers of high quality teachers and allow us to raise the standards of training, so that a huge % of students are not forced to be taught by any person willing to stand in front of the classroom. Attracting "A" quality teachers would also be helped if their benefits and retirement pensions that they were promised in lieu of decent pay were not criminally taken away.
Once teachers are in the classroom and teaching, there is nothing close to a reliable empirical method of discerning teacher quality based upon real world performance of their students. The confounding variables that impact student outcome are too numerous and many impossible to measure in order to control for them.
The best hope are measures that increase the quality of the teachers getting trained and the quality of the training. Both of these require greater financial incentives to attract smarter and more ambitious people and get them to agree to higher training and evaluation standards. It would also help if conservative stopped dehumanizing teachers and creating a culture in which teaching is viewed with such disdain. IF we could raise the bar during the recruiting and training phases, before they ever get into the classrooms, then their would be less variability in teacher quality and most would be "A" quality.
