The Manual on Police Monitoring, Mentoring and Advising in Peace Operations provides practical advice for United Nations police on what to monitor in the host-State police, what areas of police activity to pay special attention to and how to effectively turn monitoring results into programmatic activities/ targeted United Nations responses/interventions. The advising and mentoring parts of the manual describe how these activities can be performed on the basis of latest advances in peer-to-peer learning and adult education practices with a particular emphasis on the global knowledge transfer and on-the-job training ‘know-how’ in the police and other law enforcement agencies.
