MALDEN, Mass. (AP) — The state education board has placed two schools, including the first virtual school in Massachusetts, on probation for low achievement and other problems.

The Board of Elementary and Secondary Education said Tuesday that Boston Green Academy and Greenfield Commonwealth Virtual School have at least a year to show academic improvement. Failure to do so could lead to closure.

The headmaster at Boston Green Academy in Brighton said during public testimony before the vote that the problems at his school "will not and cannot happen again."

Officials at the virtual school said they were disappointed but have already addressed many of the problems, which were originally identified during a visit by state officials in June.

The online school teaches about 700 students from across the state.
