A lawsuit over whether to release performance ratings for 12,000 New York City schoolteachers based on student test scores is headed to court this week.
The city Department of Education says the public has a right to know which teachers are making the grade. But the teachers union fears its members will be unfairly subjected to ridicule based on student test scores they cannot control.
A hearing is scheduled Wednesday in Manhattan state Supreme Court.
Outgoing schools chancellor Joel Klein says the so-called value-added scores prove that not all teachers are equally effective.
But the union argues that the value-added scores cannot account for all the factors that affect student performance on tests.
