National city placement
One campus shapes the city average
According to NCES CCD 2024-25, Denville has more public-school enrollment than 45% of the 4,487 US cities in this directory. Morris Knolls High School enrolls 35.6% of Denville'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 Denville 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.
Campus spread matters more than the city mean
The 17-point gap between Valleyview Middle School and Riverview Elementary School shows the range hidden by Denville'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.
