A second call for consultants drew twice as many responses for a committee studying the sustainability of public schools in northern Berkshire County, specifically grades 6 through 12.

Amid declining enrollment and rising costs, public school districts in northern Berkshire County are exploring ways to collaborate or regionalize. A consultant specializing in education would help guide and inform the process toward an outcome.

The Northern Berkshire Regionalization Study Steering Committee rejected all three proposals it received after its first request and issued a second request with a narrower scope.

Six consultant groups responded to the second request: Academic Discoveries of Boylston, Berkshire Educational Resources K12 of Pittsfield, District Management Group of Boston, Precision Consulting of Las Vegas, Public Consulting of Boston and Vaysen Studio of Syracuse, N.Y.

Academic Discoveries, Berkshire Educational Resources K12 and Vaysen Studio also submitted proposals during the first round.

All six consultant groups were interviewed online Tuesday and Wednesday.

The 16 voting committee members will review those interviews and score each consultant group by Monday.

The committee will meet at 5:30 p.m. June 3 at McCann Technical School, where price proposals will be unsealed and scores will be finalized. Price will account for 10 percent of the final score.

John Franzoni, superintendent of the North Berkshire School Union, is one of four ex officio superintendents on the committee.

“The Steering Committee will either name finalists or vote to offer the lead role to one of the six consultants, then agree to enter into a contract with them for the work required in phase 1 of the study,” Franzoni said in an email.

District Management Group emerged as the top choice among nine committee members who initially reviewed the proposals before the interviews.

But that could change after the interviews, once all voting committee members submit scores and price is factored in.
