Short Investigation Report Template & Sample

Last updated 2026-07-30

Not every complaint needs a forty-page report. A single disputed incident with two witnesses and no policy ambiguity can be documented properly in three or four pages, and forcing it through a full-length format wastes time without adding defensibility.

What a short-form report must not do is drop the elements that make a finding reviewable. The scope, the standard of proof, the evidence considered and a finding on each allegation all survive the compression. What goes is the elaboration, not the structure.

Jurisdiction

Written primarily against US federal standards — EEOC guidance, NLRB decisions and Title VII case law — and against general investigative practice. State law, sector rules (public employers, education, regulated industries) and collective agreements impose additional requirements this page does not cover. Where a page borrows a concept from another jurisdiction it says so explicitly. Outside the US, treat the structure as transferable and the legal references as not.

When to use this document

  • A single allegation or a small number of closely related allegations.
  • The facts are largely undisputed, or the dispute turns on one narrow point.
  • The matter is unlikely to result in termination or external challenge.
  • An internal investigator is documenting a matter that was resolved quickly.

Worked example

Fictional scenario. A single-allegation matter in the same logistics company: a warehouse operative alleges a colleague swore at him during a shift handover. The colleague accepts raising his voice and denies the language alleged. Two people were within earshot. This is the whole report — the point is that four pages can be complete.

Matter details

Matter reference:
RW-2026-041
Complainant:
J. Adeyemi, Warehouse Operative
Respondent:
T. Novak, Warehouse Operative
Date received:
3 July 2026 | Commenced: 6 July 2026 | Reported: 14 July 2026
Investigator:
R. Hall, HR Business Partner

Allegation

1. That on 30 June 2026, during the 14:00 shift handover in Bay 3, the respondent shouted at the complainant and called him a 'useless waste of space'.

Scope and standard of proof

I was asked to determine whether the conduct alleged occurred and whether it breached section 4.1 of the Respectful Workplace Policy. I was not asked to recommend any disciplinary outcome. I have applied the preponderance of the evidence.

Evidence considered

Interviews:
Complainant (6 July); Witness C, Bay 3 loader (7 July); Witness D, shift supervisor (7 July); Respondent (9 July).
Documents:
shift rota for 30 June; Bay 3 handover log; Respectful Workplace Policy v3 (eff. 1 Jan 2025) and the respondent's signed acknowledgment of 14 Jan 2025.
Sought but not obtained:
Bay 3 has no audio recording and the camera does not cover the handover point. Confirmed with Facilities, 8 July.

Findings

Allegation 1: SUBSTANTIATED IN PART.

I find that the respondent shouted at the complainant during the handover on 30 June. That is not in dispute — the respondent accepts it and both witnesses describe it.

I do not find that the words 'useless waste of space' were used. The complainant is clear that they were. The respondent denies it and says he said 'this is useless' about a mis-stacked pallet. Witness C heard raised voices and the word 'useless' but cannot say what it was directed at. Witness D was ten metres away and heard shouting only. The evidence does not permit a determination on the precise words, and I have not made one.

What I do find is that the respondent shouted at a colleague across a working bay in front of at least two others, in a manner both witnesses independently described as aggressive.

Policy outcome

Section 4.1 requires colleagues to be addressed 'without hostility, ridicule or intimidation.' On the facts found — shouting at a colleague aggressively in front of others — I find section 4.1 was breached. The breach does not depend on which words were used, which is why the unresolved element does not prevent a finding.

Signature

This report reflects my own analysis. It makes no legal determination and no recommendation as to discipline.

Section-by-section guide

What each section is for, what a good one contains, and where they typically go wrong.

1.Matter details

Identifiers, parties and dates, compressed into a header block.

2.Allegation(s)

Numbered, even when there is only one — the numbering is what ties each allegation to its finding.

3.Scope and standard of proof

Two sentences. What you were asked to determine, and the standard applied. This is the section most often dropped in short-form reports and the one least safe to drop.

4.Evidence considered

A list, not a narrative. Who was interviewed and when, what was reviewed, and anything sought but not obtained.

5.Findings

A finding on each numbered allegation with a short statement of the evidence relied on. Where accounts conflicted, one or two sentences on why you preferred one.

6.Policy outcome

Which provision was engaged and whether, on the facts found, it was breached.

7.Signature

Investigator, credentials, date, and the limits of the report.

Common mistakes

The failure modes that show up most often when this document is reviewed later.

Dropping the standard of proof because the report is short

Brevity is a reason to compress the reasoning, not to remove the framework a reader needs to assess it.

Using the short form for a matter that could end in termination

If the outcome is severe, the report will be scrutinized in proportion. Match the format to the stakes, not to the number of allegations.

Writing 'no evidence of wrongdoing' instead of a finding

That phrase conflates 'we found nothing' with 'it did not happen'. State which allegation was not substantiated, and on what basis.

Questions

Can I use the short form when the respondent might be dismissed?
No. Match the format to the stakes, not to the number of allegations. If dismissal is a realistic outcome the report will be scrutinised in proportion, and a short-form report is the wrong instrument for that — use the full format from the start rather than converting later.
Our policy requires a 'full written investigation report'. Does a short form satisfy that?
Read the policy wording before deciding. 'Full' in most policies means complete as to scope, evidence, findings and reasoning — not long. A four-page report containing all four is a full report. If the policy specifies sections, follow them; a format argument is an avoidable line of attack.
I started with the short form and the matter escalated. Do I rewrite it?
Do not rewrite a report you have already issued. If it has not been issued, expand it into the full format and note in the methodology when and why the approach changed. If it has been issued, produce an addendum rather than a replacement, and preserve the original version — silently swapping a served report is far worse than the format being wrong.
When is a short-form investigation report appropriate?
When the allegations are few, the facts are largely undisputed, and the likely outcome is not termination or external challenge. If any of those change during the investigation, move to the full format.
