That concentration — well above the 8.4% national median for largest-entity share — means Cass SD 63-wide averages can mask substantial variation outside the dominant entity. Grade band: other. A single dominant campus often anchors a district's program offerings and staffing patterns; the share helps explain why district-wide averages may not reflect the typical neighbourhood-school experience. When one entity dominates a region's footprint, its programmatic and budget decisions effectively set policy for a majority of the affected population.

Cass SD 63 student-counselor ratio is 617:1 — high (typically associated with staffing constraints that limit per-student counselor time; CRDC data shows higher ratios cluster in larger urban systems)

student-counselor ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE counselors against total enrollment — districts that contract intervention or social-emotional staff outside the counselor classification may be under-counted Higher values may reflect larger urban scale or recent resource constraints that have widened the gap.

Cass SD 63 chronic absenteeism rate is 24.8% — near the typical range (US average ~28) — aligned with the national post-pandemic baseline of roughly 28% chronic absenteeism
