Diversity, equity, and inclusion (DEI) are three elements of workplace culture that help ensure all employees are treated equitably and are provided similar levels of respect, appreciation, and support for professional growth. To a large extent, the leadership, policies, and practices of an organization contribute to diversity and equity. In contrast, inclusion is a characteristic of organizational culture that results when diversity and equity are embraced and encouraged. The purpose of this paper is to provide police agencies with essential background material to provide greater understanding of the developmental philosophy and implementation requirements for fostering a more diverse, equitable, and inclusive policing workforce.
