How Arbon Elementary School compares with Idaho and U.S. medians
What stands out at Arbon Elementary School
Scale and staffing sit near the state mainstream
Arbon Elementary School is neither an extreme outlier in enrollment nor in student-teacher ratio among Idaho schools. Its profile therefore turns on the other dimensions rather than on scale alone: economic need, counselor coverage, program access, attendance, and district finance. This middle placement is useful because it prevents the campus from being mislabeled as unusually large, small, crowded, or teacher-dense when the federal comparison does not support that claim.
A combined-grade campus has a different support burden
Arbon Elementary School serves a combined grade span rather than a conventional elementary, middle, or high-school band. That structure can require the same campus to cover transitions, counseling needs, and programs for students at substantially different developmental stages, so a single staffing ratio deserves more caution than it would at a narrower-grade school. Federal totals show the available people and programs, but not how those resources are divided among grade levels.
Arbon Elementary School is a small combined-grade school in Arbon, Idaho, enrolling 18 students.
Class loads run somewhat heavier than typical: 18:1 puts it in the larger third of Idaho schools by student-teacher ratio.
