Twenty-six years of award-winning teaching have led John Gatto to some troubling conclusions about the public schools.

A seventh-grade teacher, Gatto has been named New York City Teacher of the Year and New York State Teacher of the Year. Praised by leaders as diverse as Ronald Reagan and Mario Cuomo, he’s a political maverick whose views defy easy categorization.

Gatto is also a local legend on Manhattan’s Upper West Side, where he grows garlic, plays chess, writes songs — and once won a Citizen of the Week Award for coming to the aid of a woman who had been robbed. A collection of his essays — Dumbing Us Down: The Hidden Curriculum Of Compulsory Schooling — was published earlier this year by New Society Publishers.
