No schools in New York City or the rest of the state classify as “persistently dangerous,” the State Education Department announced yesterday.

That means no student here will be able to take advantage of the provision of the No Child Left Behind law that allows children trapped in dangerous schools to transfer into safer ones.

Although the picture of school violence the list paints looks better than last year – when two New York City schools were classified as dangerous – educators and politicians from around New York said the list was no cause for merriment.

“The announcement by Commissioner [Richard] Mills that there are no dangerous or persistently violent schools in the state would be greeted with great celebration if it were true,” said the chairman of the State Assembly’s education committee, Steven Sanders. “Sadly, it is not true.”

Mr. Sanders said the list speaks not to the level of violence in schools but to the failure of the state to “develop a reliable database methodology to identify such schools.”

Under the state formula, schools classify as persistently dangerous if the number of weapons incidents in the school year divided by the number of students at the school is 3% or greater for two consecutive years. Incidents that involve assault or sexual assault do not count.

The president of the United Federation of Teachers, Randi Weingarten, chuckled about the state’s findings.

“When you put out a list like that, it bespeaks questioning the credibility of the list,” she said.

A spokesman for the city’s Department of Education, Keith Kalb, said the department is “pleased” that the two schools that were dangerous last year “dramatically improved their environments” and came off the list.

A city lawyer who represents victims of school violence, David Lesch, said the state’s findings seem “skewed.”

He said in the last year, he has represented students who have been seriously hurt at school but whose schools don’t show up on the list.

At Adlai Stevenson High School, a girl stabbed a boy with a box cutter that she snuck past the metal detector. At Washington Irving, five students jumped and badly hurt two sisters.

“Obviously this report is skewed,” he said. “A fist can be as bad as a weapon, as a knife. Nails can be a weapon when scratched across the face or into the eye.”
