PEACE Model
Ethical investigative interviewing for accurate and reliable information gathering. This interactive article explains how investigators can plan properly, build professional rapport, obtain a full account, close interviews clearly and evaluate the information gathered.
What the PEACE Model helps investigators do
The model shifts interviewing away from confession-driven pressure and toward professional information gathering, fairness, careful questioning and defensible decision-making.
A truth-seeking interview model
The PEACE Model is a five-stage framework for investigative interviews. It helps investigators prepare the interview, engage the interviewee, obtain a reliable account, close the session properly and evaluate both the information and the interviewer’s performance. It is useful because interviews can easily become weak when the interviewer rushes, assumes guilt, asks leading questions or fails to review the evidence.
In professional investigations, the aim is not to force agreement with a preferred theory. The aim is to gather accurate information that can be tested against evidence, timelines, documents, digital records and other accounts. This makes the model suitable for criminal investigations, workplace inquiries, fraud cases, compliance reviews, security incidents and victim or witness interviews.
Core learning message
PEACE protects the quality of the interview. It reminds investigators to plan before questioning, explain before exploring, listen before challenging, close before leaving and evaluate before relying on the account.
- It reduces coercion and unfair pressure.
- It supports accurate and reliable accounts.
- It improves professional interviewing discipline.
- It creates a structure that can be taught, practised and reviewed.
Why the model became important
Founder and origin of the PEACE Model
The PEACE Model is commonly associated with investigative interviewing reform in the United Kingdom and with the work of Eric Shepherd and the UK Investigative Interviewing Group. It was developed in the early 1990s as a structured response to concerns about coercive interviewing, confession-focused practices, unreliable admissions and wrongful convictions. Its foundation is ethical information gathering, not pressure-based interrogation.
From confession pressure to information gathering
The PEACE Model developed in the United Kingdom during the early 1990s as part of investigative interviewing reform. It emerged after concerns about coercive interviewing, unreliable admissions, false confessions and wrongful convictions. The model placed stronger emphasis on lawful treatment, professional communication, structured questioning and reliable evidence-based inquiry.
Why it still matters today
Modern investigations face high scrutiny. Interview records may be reviewed by courts, management, regulators, disciplinary panels, auditors, parents, unions or public authorities. A poor interview can damage a strong case. PEACE helps investigators show that the interview was prepared, fair, respectful, relevant and properly evaluated.
The PEACE stages

Planning and Preparation
Planning and Preparation gives the interview its professional direction. Before asking any question, the investigator reviews the allegation, available documents, statements, CCTV, digital records, timelines, policies, legal requirements and unresolved information gaps. The purpose is to know what has already been established, what still requires clarification and what the interview must achieve. A planned interview is not a scripted interrogation. It is a structured information-gathering exercise that protects fairness and improves accuracy. The investigator should prepare open questions, identify possible evidence to test later, consider the interviewee’s role, arrange a suitable room, check recording arrangements and consider language, vulnerability, support-person or legal requirements. Poor preparation often leads to repeated questions, missed leads, weak control and unreliable answers. Strong preparation allows the interviewer to listen better because the structure is already clear. This stage reminds investigators that the quality of an interview is often decided before the interview starts.
How PEACE works during an investigation
Prepare the interview direction
Review the case material, clarify the interview purpose, identify evidence gaps, prepare open questions and plan the setting.
Open with clarity and professionalism
Explain who you are, why the interview is being conducted, how the process will run and what rights or safeguards apply.
Obtain the account
Invite a free narrative first, listen actively, expand with open questions, clarify unclear points and avoid leading the interviewee.
Close properly
Summarise key points, invite corrections, ask if anything else should be added and explain the next steps.
Evaluate the value of the interview
Compare the account with evidence, identify new leads, assess gaps and reflect on the interviewer’s own performance.
Workplace fraud interview example
A suspected employee is linked to unusual transactions, missing approvals and irregular expense claims. Use PEACE to guide the interview.
Planning and Preparation in the fraud case
The investigator reviews transaction records, approval workflows, expense forms, system access logs, emails and the employee’s job responsibilities. The purpose is not to assume guilt but to identify what must be clarified. The investigator prepares objectives such as confirming who created the claims, who approved them, whether supporting documents exist, whether the employee had authority and whether any instruction came from another person. The investigator also prepares open questions about routine processes before moving to specific transactions. This prevents the interview from becoming a direct accusation at the start.
Engage and Explain in the fraud case
The investigator opens calmly, explains the role of the interviewer, outlines the purpose of the meeting and describes how the interview will be conducted. The employee is told that they will have an opportunity to explain the transactions and provide any relevant context. The interviewer explains recording or note-taking arrangements and the need for accurate information. This stage helps reduce defensiveness and sets a professional tone. It also prevents the employee from later claiming that the purpose was unclear or that they were not given a fair opportunity to respond.
Account in the fraud case
The employee is invited to explain their normal claim process and then the specific transactions under review. The investigator allows a free account before asking follow-up questions about dates, documents, approvals, access, instructions, business reasons and any unusual circumstances. The interviewer avoids asking questions such as “You knew this claim was false, correct?” because that is leading and accusatory. Instead, the interviewer asks, “Can you explain how this claim was prepared?” and “What documents supported this entry?” The account can then be tested against financial records and system logs.
Closure in the fraud case
The investigator summarises the employee’s main explanations, including any claimed authorisation, missing documents, timing issues or alternative explanations. The employee is invited to correct the summary or add further information. The investigator may ask whether there are additional emails, messages, receipts, witnesses or instructions that should be reviewed. The next steps are explained, such as comparing the account with finance records and other witness interviews. The interview ends professionally, even if serious concerns remain. This protects fairness and preserves the integrity of the process.
Evaluation in the fraud case
After the interview, the investigator compares the account with expense records, approval logs, email trails, finance policies and witness statements. They identify which parts of the account are supported, contradicted or still unclear. If the employee says a manager approved the claim, the investigator checks whether the approval exists and whether the manager confirms it. The investigator also reviews their own interview performance: Were questions open? Was the employee allowed to speak? Were key issues missed? Evaluation determines the next investigative steps and improves the reliability of the final findings.
Where the PEACE Model can be applied
Filter the examples by investigation context.
Why PEACE strengthens interviews
The model reduces coercion, intimidation and unfair pressure. This makes the interview easier to defend when decisions are reviewed by managers, lawyers, regulators or courts.
Free narrative, open questions and careful clarification help the interviewee provide fuller and more reliable information.
Because PEACE is not confession-driven, it avoids many risks linked to aggressive or guilt-presumptive methods.
The five stages help investigators prepare, communicate, listen, close and evaluate in a disciplined way.
The model can support criminal, workplace, compliance, healthcare, school, public-sector and security investigations.
Evaluation encourages continuous improvement in questioning, listening, rapport-building and evidence awareness.
Limitations and cautions
Investigators need skill in questioning, active listening, rapport, evidence assessment and managing difficult behaviour.
Good preparation, open questioning and evaluation require discipline and time, especially in complex cases.
The model guides the interview but does not replace law, policy, procedural fairness or investigator competence.
Aggressive, evasive or manipulative interviewees require calm control, clear structure and evidence-focused follow-up.
Rights, caution, recording, confidentiality, interpreters and support requirements must be followed where applicable.
The interview account must still be tested against independent evidence and alternative explanations.
Common myths PEACE helps prevent
Myth: A good interview is one that gets a confession.
PEACE focuses on accurate and reliable information, not forced admissions.
Myth: Strong pressure produces truthful answers.
Pressure can increase confusion, resistance and false or unreliable information.
Myth: Rapport means being too friendly.
Rapport means professional trust, respectful communication and clear explanation.
Myth: Planning makes the interview rigid.
Planning gives direction while still allowing flexible follow-up questions.
Myth: Closed questions should dominate the interview.
Open questions support fuller accounts before clarification is used.
Myth: The interview ends when questioning ends.
Evaluation after the interview is a core part of the PEACE cycle.
Myth: Ethical interviewing is weak.
Ethical interviewing protects the investigation and improves defensibility.
Myth: The same style works for everyone.
Good interviewers adapt tone, pace and support to the person and case context.
