The average student-teacher ratio across the city is 13.9:1, Schools must report at least five campuses in a city to appear in this listing, which is why very small towns may redirect to the broader county or state view.

Families should treat any single ranking as a starting point rather than a verdict — a school serving fewer at-risk students or offering more AP classes will score higher on resource-based composites even if individual teachers or programs elsewhere are stronger.
