PurposeIncident commanders (ICs) are senior police officials tasked with being the key operational decision-makers and leading a command team during major, critical and public order incidents (e.g. bomb threats, hostage situations and protests). Such events are often characterized by heavy time pressures and little information, requiring a highly skilled, integrated emergency response across multiple agencies and significant police planning, organizing and management. ICs must possess the necessary skills, traits and behaviors to deal with such incidents and their challenges. Therefore, the purpose of this study is to identify the competencies of ICs.Design/methodology/approachWe conducted a thematic analysis of thirty-eight (n = 38) in-depth interviews with police personnel who have professional experience as ICs.FindingsResults provided information on the competencies important for effective incident command, including a range of skills, traits and behaviors these police personnel should exhibit, such as command presence, decision-making, confidence, risk assessment, teamwork, task management, stress management, humility and others.Originality/valueWe provide a novel literature contribution by proposing a framework of police IC competencies and their interrelatedness based on first-hand interviews with experts in the field. Practitioners and policymakers need to know actionable strategies for developing standardized training and assessment curricula for ICs. The next steps are to delineate what skills, traits and behaviors are trainable and need to be selected for at the time of recruitment (e.g. occupational aptitude, personality). We provide the foundation upon which researchers and practitioners can make actionable decisions on moving forward to attain these important goals.
