The Police Station Visitors Week (PSVW) is a unique global event organised by Altus to assess the quality of service delivered in the participating police departments, to identify some of the best practices in use by police, and to strengthen the accountability of police to the local citizens whom they serve. A system of annual visits by groups of citizens to local police stations, coordinated globally and designed to produce comparable annual scores on five dimensions of police service: Community Orientation, Physical condition, Equal Treatment of the Public, Transparency and Accountability, Detention conditions. The overarching goal of the program is to measurably improve the quality of local police service according to international standards as interpreted by local communities, especially those who are poor and marginalised. This, in turn, contributes to improving trust and cooperation between police and communities, leading to greater reliance on police by crime victims and improved access to justice.
