Principle 4. Client Risk/Need Practices

Offender risk is assessed by psychometric instruments of proven predictive validity. The risk instrument includes a wide range of dynamic risk factors, or criminogenic needs (e.g., antisocial attitudes and values). The assessment also takes into account the responsivity of offenders to various styles and modes of service. Changes in risk level over time (e.g., three to six months) are routinely assessed in order to measure intermediate changes in risk/need levels that may occur as a result of planned interventions.
