A nearly 10-year effort to significantly overhaul the Island’s oldest town school is headed back to voters in Tisbury, where in June they will be asked to approve a $55 million bond measure.

The up-Island and Tisbury School committees voted this week to authorize their share of the funding for a school-wide testing program, just as the first Covid-19 cases have been identified in the school system.

The Tisbury School reported its second positive case on Monday and the Edgartown School reported its first. The cases come two days after a student who attends the Tisbury school tested positive on Friday.

A student at the Tisbury School has tested positive for Covid-19, Tisbury health agent Maura Valley confirmed Friday. School superintendent Matt D'Andrea wrote that an individual had tested positive in an earlier letter to parents.

Tisbury School students got a private performance Tuesday by an internationally acclaimed dance ensemble from Cuba.

On Friday, at their first assembly as a unified student body since the spring of 2019, nearly 300 Tisbury School students cheered and clapped when their school mascot took the floor.
