Over at Bluff City Ed, there’s an article analyzing the new pay scale for teachers in Shelby County Schools. The scale is weighted toward TVAAS data and the evaluation rubric, which rates teachers on a scale of 1-5, 1 being significantly below expectations and 5 being significantly above. A teacher earning a 3 “meets expectations.” That means they are doing their job and doing it well.

Jon does a nice job of breaking down what it means to “meet expectations.” But, here’s the problem he’s highlighting:  Teachers who meet expectations in the new system would see a reduction in their annual step raise. That’s right: They do their job and meet the district’s performance expectations and yet earn LESS than they would with the current pay system.

Jon puts it this way:

But what the district outlines as meeting expectations exemplifies a hardworking and effective educator who is making real progress with their community, school and students. If a teacher is doing all these things, I believe that they should be in line for a yearly raise, not a cut. At its core, this new merit pay system devalues our teachers who fulfill their professional duties in every conceivable way.

I would add to this argument that to the extent that the new pay scale is based on a flawed TVAAS system which provides minimal differentiation among teachers, it is also flawed. Value-added data does not reveal much about the differences in teacher performance. As such, this data shouldn’t weigh heavily (or at all) in performance pay schemes.

Systems like Shelby County may be better served by a pay scale that starts teachers at a high salary and rewards them well over time. Increasing pay overall creates the type of economic incentives that both attract strong teachers and encourage school systems to develop talent and counsel out low performers.

Shelby County can certainly do more to attract and retain strong teaching talent. But the new pay scale is the wrong way to achieve that goal.
