The United Nations Police Gender Toolkit: Standardised Best Practices on Gender Mainstreaming in Peacekeeping is a blueprint for the implementation of gender-related activities in policing mandates. Addressing gender-related concerns within conflict and post-conflict environments, it focuses on helping United Nations Police (UNPOL) officers to apply a standardised methodology and coherent approach across peace operations. In three modules, it covers lessons on how to apply gender concepts to policing; how to develop a police gender strategy and action plan; how to assist the host State police in developing and implementing a gender equality policy and recruiting female police officers; and how to establish special police units to address sexual and gender-based violence (SGBV). As a training package, it consists of materials for both a self-paced e-learning and in-person course with a training curriculum, a handbook and a compendium of project tools. It offers a range of standardised processes, model policies, procedures and strategies, templates, checklists and sample questionnaires to guide implementation in the field mission. The tools have been developed from proven good practice from police services worldwide.
