That dominant concentration means Castlewood School District 28-1-wide averages can mask substantial variation outside the dominant entity. Grade band: combined. 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.

Castlewood School District 28-1 student-counselor ratio is 86:1 — well below typical (typically associated with unusually small scale or exceptionally high per-unit investment)

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 Values this far below typical often correlate with unusually small scale or population characteristics rather than higher resource budgets per se — worth checking whether the underlying denominator is itself an outlier.
