The Cohoes Board of Education and its teachers’ union have agreed to a new four-year contract that will lengthen the school day at all grade levels.

The board Wednesday unanimously approved the new deal, which will be in effect through the 2020-21 school year. The contract is retroactive to July 1, 2017 as teachers worked under an expired contract this year.

Under the agreement, the elementary school day will be lengthened by 35 minutes, with additional time devoted to daily lessons in science and social studies. The middle school day will increase by 22 minutes and the high school by 20 minutes.

"We believe the more time our students spend in the classroom, the more successful they will be," Cohoes Superintendent Jennifer Spring said in a prepared statement about the contract. "The length of our school day hasn’t changed in more than 50 years. With increased curricular requirements, teachers need additional time to effectively teach the standards and we want them to be properly compensated for this additional effort.”

The Cohoes Teachers Association has almost 300 members. Under the contract, they will receive a yearly salary increase of 2 percent.

“Our negotiations team worked collaboratively with the district on a contract that was fair and equitable for our members ​and​ also helped to provide more instructional time for the students of Cohoes,” said CTA President Scott Ciarlone. “As with most contract negotiations, there is always give and take, but I am confident that the agreement benefits both the district in their areas of focus and initiatives and the issues that matter most to the members of the CTA.”

The union approved the contract in a 175-23 vote.

The latest contract pay scale runs from $43,271 to $84,682 at the top of the longevity scale.
