St. John and Endicott maintain two school districts while sharing most of the secondary years. Each town keeps an elementary school. Students in the middle grades attend Endicott–St. John Middle School in Endicott, and grades nine through twelve come together at St. John–Endicott High School in St. John. The direction of travel changes with age, so the cooperative is experienced through bus routes as well as school names.
The shared schools give two small Palouse communities larger peer groups for classes, athletics, music and student organizations. Staff assignments can cross age levels and towns, and public events draw families from both places. Elementary identity remains local while middle- and high-school life is built around the Eagles cooperative.
Community service also crosses the district line. The National Honor Society Giving Tree organizes requests and gift distribution through schools and businesses in both St. John and Endicott, placing students in a practical role within family support. Two boards continue to meet and govern their own districts, yet students experience a single secondary pathway. The cooperative works because local elementary roots and shared adolescent life are both allowed to remain visible.
