That concentration — well above the 8.4% national median for largest-entity share — means Two Rock Union-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.
