MINNEAPOLIS — The Minneapolis school district says it has reached a tentative contract settlement with its teachers.

District officials say the announcement was made Monday.

Details of the settlement aren’t expected to be released before next Monday. That’s according to a message sent to district employees and signed by Superintendent Bernadeia Johnson and Minneapolis Federation of Teachers President Lynn Nordgren.

The Minneapolis Star Tribune says the tentative contract must still be approved by teachers and the school board.

The negotiations took 1½ years. They were often acrimonious, particularly over two sticking points.

The district wanted to freeze salaries and eliminate automatic pay increases. It also decided not to make payouts under a system that pays teachers extra for working outside the classroom to improve their skills.
