National city placement
One campus shapes the city average
According to NCES CCD 2024-25, Andover has more public-school enrollment than 74% of the 4,487 US cities in this directory. Andover Ecademy enrolls 44.3% of Andover's public-school students. That is enough concentration for one institution to pull the citywide enrollment, staffing, and Resource Index averages toward its own profile. The smaller campuses below should therefore be compared directly rather than inferred from the headline mean; their grade configurations and program footprints can be materially different even inside the same district.
A full K–12 ladder sits inside the city boundary
Andover's list includes 1 elementary, 2 middle, and 2 high-school campuses, plus 3 combined-grade records. The city average spans every major grade stage, so the ranked table is more informative when read within level than as one interchangeable queue.
One district, but meaningful resource variation
Andover's schools share one district authority while their average Resource Investment Index ranks at the 78th 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 14-point gap between Andover Ecademy and Cottonwood 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.
