About the programme
Course Overview
An interview that pressures someone into a false admission, or fails to draw a genuine one out of someone who is guilty, can undo months of otherwise sound investigation work, which is why structured interviewing is treated as a distinct skill rather than a natural extension of conversation. This course builds interviewing skill around a recognised investigative framework, moving from rapport-building and open questioning through to structured account-gathering and, where justified, an ethical admission-seeking approach that avoids coercion or contamination of evidence. Participants practise techniques for interviewing witnesses, including methods that improve the accuracy and completeness of recall, alongside methods suited to a subject who has a direct interest in the outcome. Sessions cover planning an interview, managing resistance and inconsistency without confrontation, recognising the legal and ethical limits on questioning, and documenting an interview so the record supports rather than undermines the investigation. Practice runs through recorded role-play interviews with feedback against a structured framework, not general conversational tips.

2 sessions · 8 points
Session 1Opening, Rapport and Free Recall
- Open an interview by explaining purpose, process and the interviewee's position clearly.
- Build rapport quickly without appearing to manipulate or unduly influence the interviewee.
- Use open-ended prompts to obtain an uninterrupted free account before detailed questioning.
- Avoid leading questions that could later be seen as shaping the interviewee's account.
Session 2Improving Recall and Clarifying the Account
- Apply techniques that help a witness reconstruct context to improve accurate recall.
- Probe gaps and inconsistencies in an account through neutral, non-suggestive questioning.
- Summarise an account back to the interviewee to confirm accuracy before closing.
- Record the interview in a form that preserves the interviewee's own words.
03Admission-Seeking Interviews Within Ethical Limits
2 sessions · 8 points
Session 1Structuring an Ethical Admission-Seeking Interview
- Establish the factual and evidential basis required before an admission-seeking interview.
- Present evidence to a subject in a manner that invites explanation rather than assumes guilt.
- Distinguish legitimate persuasion from pressure that risks an unreliable admission.
- Recognise the point at which a subject's right to representation or silence must be respected.
Session 2Managing Denial, Resistance and Inconsistency
- Respond to denial by testing an account against evidence rather than repeating an accusation.
- Identify verbal and behavioural inconsistency without over-interpreting normal nervousness.
- De-escalate a defensive or hostile interviewee to keep the interview productive.
- Know when to pause or end an interview that has become unproductive or improper.
04Documentation, Review and Cross-Cultural Practice
2 sessions · 8 points
Session 1Documenting the Interview for Evidential Use
- Produce a contemporaneous record that distinguishes direct quotes from paraphrase.
- Note non-verbal observations factually without presenting them as proof of deception.
- Have an interviewee review and confirm a written record where process requires it.
- File interview records so they integrate with the wider investigation case file.
Session 2Adapting Technique to Context and Culture
- Adjust interview style for cultural, language or power-dynamic differences with an interviewee.
- Work effectively with an interpreter without losing control of question sequencing.
- Recognise how trauma or distress can affect recall and adjust pacing accordingly.
