The training program template
Seven modules following a case from intake to outcome. Run the full set to certify an investigator, then use the refresher and calibration modules to keep them current.
| Module | Audience | Duration | What it must cover |
|---|---|---|---|
| 1. Intake, scope and conflicts | All investigators | 25 min | Taking a complaint, defining the allegations and scope, and checking for conflicts of interest before starting. |
| 2. Planning and confidentiality | All investigators | 20 min | The investigation plan, who needs to know, confidentiality limits, and managing the parties during the process. |
| 3. Evidence handling | All investigators | 30 min | Securing documents, messages and logs early, chain of custody, and what is and is not admissible or relevant. |
| 4. Interviewing technique | All investigators | 35 min | Open non-leading questions, separate interviews, contemporaneous notes, and supporting a distressed party. |
| 5. Natural justice and fair process | All investigators | 25 min | Putting the allegations to the respondent, the right to respond, the right to be accompanied, and avoiding bias. |
| 6. Findings and documentation | All investigators | 30 min | The balance of probabilities, reasoning findings against the evidence, and writing a defensible report. |
| 7. Outcomes and refresher | Investigators, HR | 20 min | Recommendations versus decisions, communicating outcomes, closing the case, and a knowledge check for evidence. |
Delivering the modules and knowledge check through an LMS gives you dated certification per investigator, the evidence you need to show a case was assigned to someone trained and current if the outcome is ever challenged.

The most common gap is the last one. When readiness is not tracked, a serious case lands on the first available manager, and their lack of training only shows up when the outcome is challenged.
Investigator readiness at a glance
The checklist tells you what is missing overall. This matrix tells you who is ready to run a case. Score each investigator on the five capabilities a case actually needs. In Excel the readiness and gaps calculate as you type.
| Investigator | Cases | Intake / scope | Evidence | Interviewing | Natural justice | Report | Ready |
|---|---|---|---|---|---|---|---|
| ER specialist (lead) | 40+ | 2 | 2 | 2 | 2 | 2 | 100% |
| Senior HR business partner | 15 | 2 | 1 | 2 | 2 | 1 | 80% |
| HR business partner | 6 | 1 | 1 | 1 | 1 | 1 | 50% |
| Line manager pool | 2 | 1 | 0 | 1 | 0 | 0 | 20% |
| New investigator | 0 | 1 | 0 | 0 | 0 | 0 | 10% |
| Coverage at required | 40% | 20% | 40% | 40% | 20% | 52% |
The line manager pool is the exposure here: no evidence handling and no grasp of natural justice, yet they are the ones a complaint reaches first when HR is stretched. Assign their cases to a trained lead until they are certified.
The annual investigation calendar
| Timing | Action | Owner |
|---|---|---|
| Before assignment | Confirm the investigator is certified and free of conflicts. | HR / ER |
| Per case | Run the process against the checklist from intake to outcome. | Assigned investigator |
| Quarterly | Calibration session: review anonymised cases and align on standards. | ER lead |
| For new investigators | Full certification program before any solo case. | L&D and ER |
| Annual, all investigators | Refresher and knowledge check, tracked per person. | L&D |
| After any challenged outcome | Review what failed and targeted micro-training, fast. | ER and legal |
How to run it
- Get intake and scope right
Train people to take a complaint, define the allegations and scope, and check for conflicts before anything else happens.
- Preserve evidence early
Documents, messages and access logs need to be secured at the start, with a clear chain of custody, not gathered after memories fade.
- Teach interviewing that stands up
Open questions, no leading, contemporaneous notes, and separate interviews for the complainant, respondent and witnesses.
- Build in natural justice
The respondent must know the allegations and have a fair chance to respond before any finding is made.
- Document to the standard of proof
Findings on the balance of probabilities, reasoned against the evidence, in a report that a third party could follow.
- Certify before assigning cases
Only assign a case to an investigator who is trained and current, and track that readiness centrally.
Frontline teams reach 45 percent-plus completion on Disprz when training is delivered in short, mobile modules in the local language, the format this program is built for.
Common mistakes this pack prevents
- Handing a serious complaint to the first available manager with no training and no readiness check.
- Gathering evidence late, after messages are deleted and memories have faded.
- Leading interviews and reconstructed notes that fall apart under scrutiny.
- Reaching a finding without putting the allegations to the respondent, breaching natural justice.
- No dated certification records, so there is nothing to show a case went to a trained investigator.

An investigation is only defensible if the person running it was trained and you can prove it. That is the part we run.
Bring your HR, ER and manager pool to a 30-minute working session. We will show how Disprz delivers investigation training in short mobile modules and tracks who is certified and current, so you can assign a case to a ready investigator and evidence it in a two-minute export.
