The School Committee voted to go into nonpublic session Wednesday night to discuss a possible criminal matter.
The meeting was at the high school in the main office's conference room.
Those present included a few of the same people who met behind closed doors with selectmen recently — two representatives from the town's audit firm Sullivan, Rogers & Company.
Also present on Wednesday were the School District's lawyer, Selectman Jill Sullivan, School Committee members and the district business manager.
Selectmen met in closed session with the town auditors on Feb. 15.
That session was continued to March 14, said Acting Town Administrator Dave Castellarin.
Any public information that can be disclosed about the results will be disclosed after the session, he said.
Earlier, the superintendent released a prepared statement regarding the audit.
"Theand the School Department have requested the town’s auditing firm conduct a forensic audit,” Superintendent Lynne Celli said. The rest of the statement said the district would not comment on the audit while it was ongoing.
Superintendent Celli released no information on what, if anything prompted the review of books.
Forensic audits typically gather information that can be used in court.
Selectmen met in the Feb. 15, executive session “for the purposes of investigating charges of criminal misconduct and to consider the possible filing of criminal complaints,” according to a draft of the meeting agenda.
