Governor Andrew Cuomo of New York put himself squarely in the camp of corporate reform with a proposal for merit pay based on value-added metrics.

He proposes to pay a bonus of $20,000 to teachers who are rated “highly effective” on the state’s controversial and unproven value-added evaluation program.

The fact that merit pay failed in New York City, where schools were offered a bonus for raising test scores, is of no consequence to Governor Cuomo. But, to be fair, maybe he doesn’t know that.

The fact that merit pay failed in Nashville, where teachers were offered individual bonuses of $15,000 to raise test scores is of no consequence to Governor Cuomo. But, to be fair, maybe he doesn’t know that.

The fact that merit pay has been tried for a century and has never worked anywhere is of no consequence to Governor Cuomo. But to be fair, maybe he doesn’t know that (I suggest that he read Reign of Error, chapter 12).

The good news is that Mayor Bill de Blasio disagreed with Governor Cuomo, even though he needs the Governor’s support to pass his millionaire’s tax to fund his pre-K program.

De Blasio said that he favored paying extra to teachers in work in struggling schools and to teachers in math and science, but that he doesn’t believe in merit pay.

The Murdoch-owned New York Post says that de Blasio is echoing the teachers’ union line, but in fact he is reflecting what research has proven again and again: Paying teachers to produce higher test scores does not work. And even if it did produce higher test scores, it would fail because it would mean that the scores were produced by test prep, rote learning, and incentives, while sacrificing the qualities that constitute a sound education.

Bottom line: Merit pay doesn’t work. If only there were some relationship between research and experience on one hand, and what policymakers believe on the other.
