In late night negotiations, rushing to finish the legislative session, the New York Legislature reached a package deal to extend mayoral control by only one year. Part of the package creates a parallel system for charter schools, which can switch authorizers and choose one (either the State University of New York or the Board of Regents) that will give them freedom from any regulations and standards that apply to public schools. In other words, there will be one set of rules for public schools, and no rules for charter schools. This will be the first time in New York state’s history that the Legislature has officially established a publicly-funded dual school system: One sector is subject to democratic control, the other is not. One must accept (or take responsibility for) all students, the other is free to accept and reject whichever students it wants.

A one-year extension, with few or no caveats, had seemed all but cemented when lawmakers went to bed on Thursday evening. But the morning found Mr. Flanagan pushing for the funding transparency requirement, followed by the charter-school provision in the afternoon. It would effectively create a parallel system of charter schools within the city, allowing “high-performing charter schools in good standing” to switch to join the State University of New York umbrella or the Board of Regents of the State Educational Department.

Not since the era preceding the Brown decision of 1954 has a state legislature so brazenly established a two-tier system of K-12 schools.

The leader of the State Senate, John Flanagan, has made no secret of his contempt for Mayor Bill de Blasio. De Blasio helped to raise money for Democrats running for the State Senate; had they won, the State Senate would be controlled by Democrats, not Republicans. Governor Cuomo has stabbed the mayor in the back repeatedly, because he doesn’t like to share the stage with any other prominent Democrat in the state. So, the mayor had a losing hand when he asked for a three-year extension of mayoral control.

When Mike Bloomberg asked for a six-year extension in 2009, the Legislature granted it. The State Senate loved Mayor Bloomberg, because he often contributed to individual Republicans running for re-election (three years later, in 2012, the Mayor gave $1 million to the Republican campaign fund for the state senate). When Mayor Bloomberg asked for a renewal of his unlimited power over the schools in 2009, he boasted of the dramatic increase in test scores that were a direct result of his control. However, a year later, the New York Board of Regents commissioned an independent study, which concluded that the New York State Education Department had lowered the passing mark every year and test scores across the state were inflated. When they were adjusted after this revelation, the dramatic gains disappeared. NAEP scores never confirmed the boasts by Mayor Bloomberg and Chancellor Joel Klein about “historic gains.”

If anyone remembers what all these political maneuvers over control have to do with educating one million children, please remind me.
