THE BRONX - A new evaluation system will change the way teachers in the city are determined eligible for tenure or termination.

The New York State Education Department is implementing the changes since the NYC Department of Education and the United Federation of Teachers could not come to an agreement after two years of negotiations.

The new policy judges 40 percent of a teacher's grade based on student performance, including standardized test scores. The remaining 60 percent is calculated based on in-class observations by a school's principal.

The new policy will take effect for the 2013-14 school year.
