 The last decade of the 20th century was marked by substantial increases in enrollment in the elementary schools that necessitated the construction of additions to all but one of the district's six elementary school buildings.During the first year of the new millennium Westfield taxpayers approved a $22 million referendum bond to accommodate the arrival of these enrollment increases at Westfield High School.Construction at the high school began during the summer of 2001 with the replacement of all windows and the conversion of two former shop classrooms into four large classrooms for use during the 2001–02 school year.
