Despite some student resistance and new costs, the Martha’s Vineyard Regional High School is making progress with a new program to help lagging students show test improvements — which now is mandatory before they can get a diploma, guidance director Michael McCarthy told the high school committee Monday night.

Nearly $2 million in federal clean water funding awarded this week to Oak Bluffs and Edgartown is expected to bring several long-awaited wastewater projects to fruition, including a sewer tie-in for the Martha’s Vineyard Regional High School and for the YMCA now nearing completion.

For the second time in two months this week the Edgartown selectmen approved a liquor license swap between two downtown liquors stores, one seasonal, the other year-round.

The owners of Great Harbor Gourmet and Provisions on Main street and Town Provision Inc. on Mayhew Lane want to trade licenses. Still subject to approval by the Alcoholic Beverage Control Commission (ABCC), the trade is intended to allow Town Provision owner Brion McGroarty to stay open year-round, and Great Harbor owner Ben Hall Jr. to be open seasonally.

At a meeting early last week, the all-Island school committee agreed to move forward in pursuit of special legislation that would allow Island towns to form a trust agreement to cover post-retirement benefits for the school district.

“It makes more sense to do it together than to do it individually,” said Vineyard schools superintendent Dr. James H. Weiss this week. The money reserved for the benefits is generally set aside in an account by each town and invested.

Committee members had questions about the process.
