National city placement
Compact, single-district system
According to NCES CCD 2024-25, Arnold has more public-school enrollment than 34% of the 4,487 US cities in this directory. Arnold's 6 listed schools all sit inside one district, creating a compact governance structure with one budget, board, and reporting chain. That makes citywide comparisons cleaner than in places split across several districts, but it does not make the campuses interchangeable: elementary, middle, and high-school staffing needs differ. The ranked list is best read as variation inside one system rather than competition among separate local authorities.
The listed grade span is structurally narrow
Arnold's 6 listed schools do not form a conventional mix of elementary, middle, and high-school campuses. The missing or thin grade bands make all-school city averages less representative of a typical K–12 pathway; district boundaries and nearby-city options may matter more for the grades not well represented here.
One district, but meaningful resource variation
Arnold's schools share one district authority while their average Resource Investment Index ranks at the 93rd percentile among listed cities. Shared governance removes one source of policy variation, but it does not erase campus differences by grade span or enrollment. The 20-point gap between Aacps Virtual Academy and Belvedere Elementary measures the remaining local spread. Use the district-level picture for common budget context, then compare the school components to see whether staffing, counseling, gifted-program reporting, or attendance accounts for each campus's position.
