HALLOWELL — State education officials are marking voter passage of a new school system merging under Maine’s 2007 school-district consolidation law with a celebration.

Voters in Dresden, Farmingdale, Hallowell, Monmouth and Richmond last week overwhelmingly approved a proposal to merge the four school systems to comply with a 2007 state law requiring Maine’s 290 school districts consolidate into approximately 80.

The Department of Education is holding a celebration Wednesday at 10 a.m. at Hall-Dale Elementary School.
