The New Hampshire Board of Education has given the town of Rollinsford permission to move forward with a plan that could result in the town’s older students going to school in the state of Maine. The board’s unanimous vote last week approved Rollinsford’s request to opt out of an agreement that sends the town’s students in grades 7-12 to schools in Somersworth. If Rollinsford voters approve the change in March, the town would begin sending students to Marshwood High School in 2015. But it would be three years before students in grades 7-12 are attending the Maine school. Sarah Browning, of the Department of Education, tells Fosters Daily Democrat, Rollinsford voters want to make the change because they were unhappy that some of their proposals were overruled by Somersworth.
