Research Summary The prevalence of serious, violent, and chronic offenders is assessed across 5 years of delinquency referrals to a centralized juvenile justice agency. Differences in prevalence by gender and race/ethnicity and by age at first referral are compared for these youth with the other juveniles referred. Analyses examine whether subsequent official reoffending of these juveniles is predicted by similar risk and protective factors as with other youth. Stability in the proportion of youth meeting the serious, violent, and chronic classification was found. Males were more than twice as likely to be serious, violent, and chronic offenders. Serious, violent, and chronic offenders were almost three times more likely to have been first referred when 12 years old or younger. Predictive risk and protective factors are substantively different for these serious, violent, and chronic youth. Policy implications regarding appropriate delinquency interventions to address significant risk and protective factors for different subgroups of youth are discussed. Policy Implications Our study examines the prevalence rates of juvenile offenders classified as serious, violent, and chronic, thereby necessitating an analysis of resource allocation strategies for a juvenile justice agency. In light of this and other empirical findings, agency policies have been adjusted and new policies implemented, including a reduction in the number of residential beds by more than 50% in the last 3 years and reallocation of “deep‐end” resources to prevention and community‐based programming.
