National city placement
One campus shapes the city average
According to NCES CCD 2024-25, Demarest has more public-school enrollment than 14% of the 4,487 US cities in this directory. Northern Valley Regional High School at Demarest enrolls 48.8% of Demarest'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.
Secondary campuses occupy an unusually large share
2 of the 5 listed Demarest schools are classified as high schools, a substantial share of the local portfolio. Advanced-course access, counseling, and graduation-stage staffing therefore have more weight in the city Resource Index average than they do in an elementary-heavy system.
The composite and staffing measures point in different directions
Demarest's average Resource Investment Index sits at the 97th percentile, while its teacher-staffing measure sits at the 1st percentile. The 96-point percentile gap is a reminder that the index is not a class-size score: counselors, gifted-program reporting, and attendance also affect it. Compare those components directly when two schools have similar index totals; the same headline score can arise from a different mix of reported resources.
