North Fayette and Valley Community Schools combined services in 2013 with the high school in West Union and the middle school in Elgin. The new school's mascot is called the Tigerhawks, due to the merging of the schools mascots, the Valley Tigers and the North Fayette Hawks. This agreement came about as a result of low enrollment and less state aid. The agreement was intended to last until the end of the 2015–2016 school year, when the school boards could decide to either: continue the whole-grade sharing agreement, end the agreement and go back to the North Fayette and Valley school districts, or officially consolidate the two districts. In July, 2018, after overwhelming majorities from both districts agreed to the merger, the district officially became North Fayette Valley.
