I cannot find any corroboration of that fact anywhere aside from that article. Evey other piece of information I have seen does not indicate that the unions are the ones sufficiently slowing the process. The one thing related document I found from the UFT states the following:
Assuming I understand this correctly, it seems the delay occurs because the administration is delaying the pre-hearing conference because they would have to fully adjudicate the issue within the subsequent 60 days. The union rules seems to require a speedy resolution once things begin. Feel free to correct me if I misunderstand things, but I don’t see how it could take years to fire a teacher due to union rules.
Ok, what are you basing that on? The administrators themselves deem a greater number of them satisfactory based on an in-person evaluation. What makes you think your analysis is more accurate?
This makes no sense. The bell curve has no basis here at all. First, there is no guarantee that teaching ability follows a normal distribution. Second, people choose to be teachers, presumably, based on their relative ability to do so. Even if teaching ability followed a bell curve, most of the small percentage of people who choose to do it as a living could very well occupy one side of the curve in the same way it happens in other professions (sculptors, NBA players, pilots, etc.). Everyone in the NBA is a satisfactory player relative to the general population (the group occupying the entire bell curve). They may be good or bad relative to one another, but they are all great relative to the average person. You act as if “satisfactory” is such a high bar that we can’t statistically have enough people meet that standard. This is just wrong.
Again, in Florida, where they have what would seem like your ideal system, they still don’t fire teachers more often. Either way you can’t just assume that since the evaluation process finds more competent teachers than you like to believe there are means the process is meaningless. It may be as you believe it is, but you should produce at least some evidence of that. While doing so, keep in mind that half of teacher voluntarily quit within 5 years, meaning that many incompetent teachers leave the profession. There is a natural attrition that may account for high satisfactory ratings too.
