Which principle in evidence-based practice involves matching the level of service to the risk level of the offender?

The principle that involves matching the level of service to the risk level of the offender is known as the risk principle. This principle is fundamental in evidence-based practices as it emphasizes the necessity of accurately assessing an offender's risk of reoffending and tailoring interventions accordingly. By doing this, resources are allocated efficiently to those individuals who require more intensive supervision or treatment due to their higher risk levels, which can lead to better outcomes in reducing recidivism.

This approach ensures that lower-risk individuals are not subjected to unnecessarily intensive interventions, which could be counterproductive and may even lead to negative outcomes. By focusing on higher-risk offenders with appropriate levels of service, corrections systems aim to effectively manage public safety while utilizing resources wisely.
