Sammanfattning	Risk-Need-Responsivity (RNR) assessment is the dominant framework for structured assessment of justice-involved people, scoring an offender's criminogenic risk and needs to decide who receives intervention, what should be targeted, and how it should be delivered. Formulated by Donald Andrews and James Bonta, it organizes the strongest predictors of reoffending into the 'Central Eight' and converts them into a total risk score that guides the intensity of correctional supervision and treatment.	Recidivism survival analysis models the time from a release or index event until an individual reoffends, treating reoffending as a time-to-event ('failure') outcome with censoring for those not observed to fail. It applies survival methods — Kaplan-Meier curves, Cox proportional-hazards regression, and split-population models — to answer not just whether someone recidivates but how quickly and what raises or lowers that risk over time.
