An appraisal of the risk-need-responsivity (RNR)
model of offender rehabilitation and its
application in correctional treatment

The science of effective offender rehabilitation remains a very young field: dominated
theoretically and empirically by the work of a small group of Canadian psychologists.
Their achievements include the 'what works' research literature, and the RNR model
of offender rehabilitation. First disseminated in 1990, over the following 20 years, the
Risk, Need and Responsivity Principles became the core of the theoretical framework
used in those correctional systems around the world that use science as a basis for
offender rehabilitation. This paper evaluates the strengths and weaknesses of the RNR
model as a Level I rehabilitation framework. It proposes that unrealistic expectations
and mistranslations of the model into practice are contributing to concerns about its
validity and utility, and stifling needed innovation in the development both of mid-level
treatment resources, and of RNR-adherent interventions. It concludes that although
the RNR model's empirical validity and practical utility justify its place as the dominant
model, it is not the 'last word' on offender rehabilitation; there is much work still to be
done.
The scientific study of criminal justice interventions has a short history, from which the
first publications on 'the RNR model of offender rehabilitation' emerged little more than
20 years ago. Founded on three core principles of offender classification-risk, need,
and responsivity-today the RNR model remains the only empirically validated guide for
criminal justice interventions that aim to help offenders to depart from that system.
Despite the progress made, the RNR model and its growing knowledge base have had
limited impact internationally on correctional responses to offenders. The highly emotive
and politicized nature of law-and-order issues in our communities can leave little room
for the influence of science. Instead, 'truthiness'-judging the validity of ideas by their
subjective appeal, without reference to facts, logic, or data (Colbert, 2005) -may prevail.
Even in nations that both commit criminal justice resources to rehabilitation and that have
adopted the model as a matter of policy, the scope and impact of potentially effective
interventions is small compared to the systemic resources dedicated to ineffective but
'true' approaches, such as increasingly severe and diverse forms of punishment and
