Which principle ensures basic completeness of a report by including who, what, when, where, why, and how?

• A. Only the names.
• B. Only the date.
• C. 5W1H coverage.
• D. Only the conclusions.

Answer: (C)

The principle being tested is 5W1H coverage—the practice of including who, what, when, where, why, and how in a report to make it complete and self-contained. In law enforcement reporting, this six-element approach gives readers a clear, reconstructable picture of an incident. Knowing who was involved answers who the report is about; what describes the incident or action taken; when and where place the event in time and location; why explains the motive or cause when known; and how outlines the sequence of events and actions performed. Together, these elements let another officer, supervisor, or investigator understand exactly what happened, assess the results, and pursue follow-up if needed, without needing to hunt for missing details.

If you only include a subset, like just the names, the report lacks the event and context; with only the date, you don’t know what occurred or where and when exactly it happened; with only conclusions, you lose the factual basis and how those conclusions were reached. 5W1H coverage is the standard that ensures the report communicates a complete, accountable narrative.
