Out of the wide proliferation of objective classification
systems has grown a body of literature that has helped
to shape and modify the first generation of prison
classification systems. Some of these classification
studies have been conducted by state prison systems
while others have been sponsored by federal agencies–
in particular the National Institute of Corrections and
the National Institute of Justice.
The purpose of this report is to summarize the new
information and knowledge learned. Based on these
“lessons learned,” suggestions are offered to show that
credible and valid classification and risk assessment
systems are needed now, more than ever, to improve
correctional operations and performance while
reducing costs and recidivism.
