New York's largest teachers union is suing the state over changes to the teacher evaluation law.
The New York State United Teachers, along with a handful of teachers and local teachers' unions, filed suit in Albany Tuesday.
The union is challenging recent state measures that allow superintendents to impose improvement plans on teachers who receive poor evaluation scores. The suit also disputes the Education Department's ability to require changes to districts' collectively bargained evaluation plans.
NYSUT says the state's actions violate Taylor Law collective bargaining rights.
State education officials declined to respond, citing a policy against discussing pending litigation.
