Big Ridge Elementary School opened in 1960-1961 as the consolidated school assigned to receive Pine Grove students. Central View, Hickory Valley, Arevalo, and part of Burkhart were also included in the consolidation.
Arevalo Elementary School opened to students in 1st through 8th grade circa1924. Bonnie Heiskell Peters relates the origins of the name of the Arevalo School in Union County Schoolday Memories.

In the fall of 1986, Wanda Woods Cox (later Byerley), a former teacher at Pine Grove Elementary, a school with grades first through eighth, organized a reunion of former students and teachers.
Since the school was located close to the county line, students attended from Anderson and Union County. Most walked to school. Many of the early students went home for lunch.
