National city placement
Middle-of-corpus city profile
According to NCES CCD 2024-25, Troy has more public-school enrollment than 43% of the 4,487 US cities in this directory. Troy sits in the broad middle of the national city distribution rather than at a single obvious extreme. Its scale, average Resource Investment Index, and staffing position need to be read together: a middle placement on one measure does not cancel a stronger or weaker result on another. The percentile panel makes those dimensions explicit, and the school table shows where the city aggregate breaks into materially different campus profiles.
The school portfolio is elementary-weighted
6 of Troy's 9 listed schools are elementary campuses. That composition means citywide enrollment and staffing averages are influenced more by early-grade operating patterns than by the city's 2 middle and 1 high-school records. Families comparing later grades should rely on those individual rows rather than the all-school mean.
Campus spread matters more than the city mean
The 29-point gap between Hook Elementary School and Troy Junior High School shows the range hidden by Troy's average Resource Investment Index. The city figure is useful for national placement, but families ultimately choose among campuses with different grade spans, enrollment, district affiliations, and reported support fields. Start with schools serving the relevant grade level, then compare the index components rather than assuming the city average describes any one classroom.
