This stage requires the interviewer to examine whether they achieved what they wanted from the interview; to review the status of the investigation in the light of any new information that was received; and to reflect upon how well the interview went and what, if anything, could have been done differently.<ref name="ReferenceA"/>

How well the PEACE method works appears to depend primarily on how well trained the interviewers are. In a study published in the British Psychological Society related to benefit fraud, 63% of (non-police) interviewers who displayed an acceptable level of competence in their interviewing ability obtained comprehensive accounts or full confessions from subjects. Even when subjects denied any offending, these interviewers still obtained a comprehensive account of what happened. This reaffirmed the importance of eliciting and fully testing the suspects’ accounts of events. In the same study, 92% of interviewers who did not display competence in their interviewing technique failed to obtain a comprehensive account of events or a confession from their subjects.<ref> Dave Walsh & Ray Bull.

However, skill and training are not the only factors at play. Half the suspects in this study confessed even though the interviewers' skills were considered less than satisfactory. This suggests that "some suspects enter the interview room having decided to confess and will carry out this decision irrespective of the investigator’s performance".<ref> Dave Walsh & Ray Bull.

In addition to investigations into benefit fraud, several studies have noted that training the police in the PEACE model has also produced beneficial results.<ref> Dave Walsh & Ray Bull.
