In response to the diverse requirements of 21st-century police work and the increasing emphasis on community-policing philosophy, the Los Angeles Police Department has implemented changes within its academy curricula and methods of instruction, including the use of adult-learning concepts, a community policing problem-solving model known as Clients, Analyzing and Acquiring Information, Partnerships, Response, Assessment (CAPRA), and the use of scenario-based learning and simulation activities. The present study examined the inter-rater reliability of the Recruit Problem Solving Measure (RPSM), a measure developed to assess recruits' use of the CAPRA problem-solving model when responding to a written domestic violence scenario. The current study also examined the degree to which recruits' RPSM scores were related to their final academy grades and the degree to which recruits' demographics (i.e., gender, marital status, ethnicity, education, prior law enforcement experience, and prior military experience) were related to their total RPSM scores. 1786 recruits from the LAPD training academy participated in the study, including recruits from both the traditional, lecture-based academy and a revised community-oriented and problem-based training model. Inter-rater reliability was measured via intraclass correlation (ICC) using a two-way, mixed models design with absolute agreement and a weighted mean to measure the variance between raters. Overall, results indicated that the RPSM possesses strong infra-rater reliability for four of the five domains, although one domain could not be assessed due to insufficient variability. Recruits' total RPSM scores were not significantly related to their final academy grades. A small positive relation existed between gender and RPSM total scores, with higher RPSM scores being associated with female recruits, and a small positive relation existed between education and RPSM total scores. Significant main effects were shown for education and ethnicity, although their effect sizes were small. Results suggest that the RPSM shows strong intra-rater variability overall and may be useful in providing a unique method of assessing police recruits' training, although further research may be beneficial to better understand the impact of several demographic variables on RPSM scores. This study also highlights the need for future comparisons between recruits' RPSM scores and other behaviorally based methods of evaluating preparedness and professional competency.
