It took two days with a federal mediator, but Nampa administrators and union representatives have a tentative agreement on a 2016-17 contract.

On average, teacher pay would increase by nearly 5 percent — but the actual raises would vary widely. The proposed salary agreement funds a year of movement on the state’s salary schedule, and it changes pay based on postsecondary credits. As a result, teacher raises would vary from 2 percent to 14 percent.

The tentative settlement bridges a $1 million gap between Nampa School District and Nampa Education Association negotiators.

Now, the proposed agreement must be ratified. It will go to the union and the Nampa school board for a vote.

During the ongoing negotiations, district teachers have been working under terms of their 2015-16 contract — with most paid at their 2015-16 salary. If the contract is ratified, teachers would receive raises retroactive to July 1, the start of the new budget year.
