While standardized test scores have improved on the margins, California public school students continue to underperform.
A judge has ruled that New York City's Department of Education can release performance ratings for 12,000 teachers.
Justice Cynthia Kern of Manhattan state Supreme Court issued the ruling Monday. It finds that a decision to release the ratings with the teachers' names attached was not arbitrary or capricious under the law.
The judge denied a petition by the United Federation of Teachers to keep the teachers' names private.
A lawyer for the union argued last month that releasing the data would unfairly subject teachers to public ridicule.
The teacher ratings are based on how well students performed on standardized tests. Five media organizations filed Freedom of Information Law requests for them.
The media groups' lawyer, David Schulz, praised the ruling. A union spokesman said the union's lawyers are reviewing the decision.
