When an allegation of wrongdoing is made or a crime is committed, the quality of information gathered in the early stages of the investigation can make or break what follows. Poorly taken statements, leading questions, or poor technique, can produce an incomplete or contaminated account that undermines everything built on top of it. The PEACE model was developed to solve exactly that problem, and decades on, it remains one of the most effective interviewing frameworks in law enforcement.
What Is the PEACE Model?
PEACE is an acronym covering the five stages of an investigative interview: Planning and Preparation, Engage and Explain, Account, Closure, and Evaluation. Developed in the UK in the early 1990s, it was a direct response to concerns about false confessions and unreliable evidence obtained through more confrontational interview styles. Since then, it has been adopted by police forces and investigative agencies around the world.
At its core, the model is built around a straightforward principle: the objective of an interview is to obtain a person's full account of events, in their own words, as completely and accurately as possible. What investigators then do with that account is a separate matter entirely.
Breaking Down the Five Stages
Planning and Preparation comes before the interviewee even sits down. The interviewer reviews the available evidence, identifies what they need to establish, and decides on their approach. This shapes every area that is discussed, every question asked and every decision made in the room.
Engage and Explain sets the tone for what follows. The interviewer introduces themselves, explains the purpose of the interview, and outlines what the interviewee can expect. Where relevant, rights are clearly explained. An important but often underestimated part of this process is rapport building. A person who understands the process and feels respected is far more likely to give a full and detailed account.
Account is where the substantive work happens. The interviewee is invited to give a free narrative, their version of events, in their own words, without interruption. Questions are posed from open questions to more closed questions for clarification purposes. Rather than directing the interviewee toward particular answers, the interviewer creates the conditions for that person to say as much as possible. The account belongs to them and the interviewer's job is simply to draw it out as completely as possible. The account phase also includes clarification and challenge and certainly the challenge phase, if required, has to be planned carefully.
Closure brings the interview to a structured end. Key points are summarised, the interviewee has an opportunity to add anything they feel was missed, and the tone is kept professional throughout. A well-handled closure can leave the door open for further cooperation later in an investigation.
Evaluation happens after the interview has concluded. The interviewer assesses what was said, identifies gaps or areas requiring further exploration, and determines what the next steps should be.
Why the Model Works: More Account Means More to Work With
One of the less obvious but highly significant advantages of the PEACE approach is what a detailed, uninterrupted account produces in practice. The more a person says, whether they are a witness, victim, or suspect, the more material they generate that can subsequently be examined.
A free narrative is rich with specifics: times, locations, names, routes taken, phone calls made, conversations recalled. Where those details align with other evidence, that alignment is noted. Where they don't, investigators have a documented account containing specific, attributable statements that can be tested and, where appropriate, disproved. The person has generated that material themselves, without being led or pressured into it, which is precisely what gives it its investigative and evidential value.
This is fundamentally different from an interview approach that seeks only yes or no answers or is only interested in a suspect making a confession. The brevity of a closed-question interview limits what is captured. The PEACE model, by encouraging people to give extended accounts, produces a far richer record and gives investigators much more to work with at every subsequent stage.
Managing No Comment Interviews
A common misconception is that a no comment interview renders the PEACE model redundant. In practice, the opposite is true.
When a suspect exercises their right to silence, a PEACE-trained interviewer doesn't abandon the process. Questions are still put clearly on the record, regardless of whether they are answered. This creates a documented account of what the person was asked and chose not to respond to, which carries its own significance.
It also preserves the structure for what comes next. Suspects who initially refuse to engage sometimes reconsider, and when that happens, the groundwork laid in the original interview provides the framework for productive follow-up. The PEACE model gives interviewers the professional discipline to conduct a thorough interview even when cooperation is refused, and to document that process in a way that holds up to later scrutiny.
The Broader Value of Ethical Interviewing
There is sometimes a perception that ethical interviewing is a constraint, a set of rules that limits what investigators can do. The evidence points the other way. Coercive or poorly conducted interviews produce thin, unreliable accounts, generate legal challenges, and have historically contributed to wrongful outcomes. The PEACE model reduces those risks while producing better, more detailed accounts from the people being interviewed.
For any organisation involved in investigations, whether law enforcement, regulatory bodies, HR departments, or legal teams, understanding and applying these principles isn't just good practice. It's the most effective way to capture what a person says happened, in a form that actually stands up to scrutiny.
