Residents of Lisbon and Durham will hear a presentation on a community school district at meetings in each town this week.

The proposal, which is a plan for a jointly owned high school, was formulated by a committee appointed by each town’s school committee and composed of residents from both towns.

Each town will hold a special town meeting in December to vote on the district, probably by referendum ballot. If approved by voters, a school committee consisting of five members from each town would be elected. In addition, a cost-sharing formula would be established as determined by state law, based on a combination of town valuations and student population. However, Durham students would not be “grandfathered” – that is, they would not be allowed to complete their educations in the high school they currently attend. Permitting grandfathering could cost more than $200,000 for each town, as estimated by Jim Rier, a state Department of Education finance specialist.

An informational forum will be held in Lisbon at 7 p.m tonight at the new Community School on Mill Street, and a meeting will be held in Durham at 7 p.m. Thursday at the elementary school gym.
