Mayor Bill de Blasio has announced that he has chosen Richard Carranza, currently superintendent of schools in Houston Independent School District to be the next chancellor of the New York City public schools.

Before starting work in  mid-2016 in Houston, Carranza was superintendent of schools in San Francisco for four years. He has also worked in Las Vegas and Tucson.

The good aspect of the choice: Carranza is not a hand-me-down from the Bloomberg-Klein regime.

The worrisome aspect of the choice: Carranza has no experience in the labyrinthine politics of New York City education or New York City politics, or Albany politics. He has a lot to learn.

Frankly, as I wrote again and again during the Bloomberg years, mayoral control is a failed concept. The mayor and his wife made the selection without a search committee. Bloomberg picked a new chancellor that he met at a cocktail party; she last three months.

It is time, past time, to restore an independent Board of Education to the City of New York, where members are not controlled solely by the Mayor and are part of any consequential decision making.
