What this grade can and can't tell you

  • The underlying data is self-reported by agencies, one yearly snapshot at a time.
  • Allegations are not findings; many complaints end unfounded, exonerated, or not sustained.
  • There is no arrest, population, or call-volume denominator in this data, so nothing here is a per-capita misconduct rate.
  • A higher internal affairs volume is ambiguous: it can indicate more misconduct, or a more robust oversight and reporting culture. The grade weighs it anyway, because volume is what the record offers; that choice is published, not hidden.
  • The grade is one lens. Weights are a transparent editorial choice on the methodology page, and the records are always one click away.

Questions and answers

What is Denville Police Department's police report card grade?
Denville Police Department receives a grade of C on this site, meaning its reported internal affairs volume and discipline severity place it in the 57th percentile of its peer group (municipal police agencies, 1-14 officers). The grade is analysis, not an official rating, and a higher volume can reflect more misconduct or a stronger reporting culture.
How is the report-card grade calculated?
The grade combines three components, each ranked within a peer group of the same agency type and size: internal affairs volume per officer (40%), sanction-weighted discipline severity (40%), and mean allegation severity (20%). The combined standing is re-ranked among peers, and the grade is the fifth of the peer group it falls in. Full method and weights are on the methodology page.
