Police reform, including transparency and officer and agency accountability, is a top priority. In response to patterns of excessive force and misconduct, reform agreements have been instituted, and consistently require early intervention (EI) systems, a supervision and accountability tool to address at-risk officers. Yet little is known about the likelihood and timing of recurring EI alerts. This study examines EI data from a large, metropolitan police agency in the southwestern USA. Results indicate officer race, division, time to initial alert, type of performance indicator, and year of the alert were significant for the likelihood and timing of subsequent EI alerts. Supervisor tenure was also significant for timing to a subsequent EI alert. For officers with a subsequent EI alert, half recurred within 6 months of their initial EI alert and intervention, and 90 per cent did so within 2 years. Implications for police reform include enhanced supervision and accountability with EI systems.
