The Mount Diablo Unified School District, the largest school system in Contra Costa County, has reached a new contract with teachers calling for a 2.3% salary increase retroactive to July 1.
Further pay increases were negotiated for 2026-27 and 2027-28, along with fully paid Kaiser Permanente health benefits as part of the CalPERS Health Program beginning Jan. 1, 2026, the school district said Friday night.
The three-year collective bargaining agreement covers teachers in the Mount Diablo Education Association who serve more than 29,000 students at 50 school sites in cities including Concord, Pleasant Hill and parts of Martinez, Pittsburg and Walnut Creek.
The tentative agreement updates class size guidelines, expands personal necessity leave options, and sets no cap on prior years of qualifying experience for initial placement on the salary schedule, the district said in a press release.
The tentative agreement goes before the education association’s members for ratification and then to the school district’s board for approval. Both sides have agreed to recommend ratification and adoption of the full agreement.
“This agreement continues our commitment to student learning and achievement, fiscal responsibility, positive labor relations, and long-term stability, while striving to offer competitive compensation and a positive working environment for all employees,” the district said in a press release.
