Surely there is some kind of compromise between paying teachers based solely on seniority and level of training, and a pay scale predicated purely on the achievement of their students.
The first position (which is consistent with union philosophy) completely leaves out the possibility that there may be better teachers and worse teachers, regardless of how much time they have put in.
The second, which is to tie raises and job security to how students score on the FCAT, rewards or penalizes teachers based on what is in effect a lottery. If a teacher is fortunate enough to be given a class drawn from a relatively well-off population, where families are involved in their children's learning and have the time to encourage them with their studies and other intellectual pursuits, then it follows that these kids will be better test-takers.
Unfortunately, both positions are politically charged, and neither is completely fair, either to the students or the professionals who instruct them.
And then there's the whole matter of whether teaching to a test makes any sense in the first place.
