Selecetmen voted 3 to 2 against seeking state assistance for a new elementary school. The vote came at a joint meeting Tuesday evening of the selectmen, the Finance Committee, the School Committee, and members of the town’s building committee, at which officials were pressed by parents of school-aged children to take steps to replace the town’s deteriorating elementary school. While the Massachusetts School Building Authority has sought a show of support for a school construction project, town voters have more than once rejected school building projects. Tuesday’s vote opposed a plan to send the state a “statement of interest” in obtaining state funds. Selectmen also voted 3 to 2 not to put a referendum on the project on this year’s town election ballot. Officials, however, believe school supporters will petition to put the project on the ballot again this year.
