That concentration means Deerfield Sd 109-wide averages can mask substantial variation outside the dominant entity. Grade band: elementary. 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.
Deerfield Sd 109 student-counselor ratio is 425:1 — 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.
Deerfield Sd 109 chronic absenteeism rate is 6.7% — well below typical (typically associated with unusually small scale or exceptionally high per-unit investment)
chronic absenteeism rate is the simplest comparative metric but it does not capture the full picture: a student is chronically absent if they miss ≥10% of enrolled days for any reason, illness, family obligations, or disengagement 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.
