Colorado Actuarial Risk Assessment Scale (CARAS)
The Division of Criminal Justice is mandated by statute
to develop actuarial risk assessment instruments for use by the
state parole board when it considers inmates for release to parole
supervision. Over the years, the Colorado Actuarial Risk Assessment
Scale (CARAS) has been revised many times to accommodate changes
in the characteristics of prisoners. The CARAS applies to both men
and women.
Accompanying is a brief description of the current version (5) of the CARAS, external reviews by criminologists Christopher Baird and Gerald Gaes, an overview of the CARAS in PowerPoint presentation format, and the scale (with item weights and scoring categories).

Sex Offender Risk Assessments (SORS, SVP, and
the SOMB Checklist)
The General Assembly also mandated that DCJ develop
a risk assessment tool to assist in the determination of sexually
violent predators (SVPs). An offender's score on the Sex Offender
Risk Scale (SORS) is one of four criteria identified by the state
Sex Offender Management Board (SOMB) to be included in the recommendation
to the court regarding the SVP designation for offenders whose crime
qualifies for possible SVP status, per Colorado Revised Statute
18-3-414.5(1). The SORS, then, is incorporated into a larger decision-making
tool (the Colorado Sexually Violent Predator Assessment Screening
Instrument).
The SORS was developed using actuarial methods and
cannot be modified without additional empirical research. The non-SORS
SVP designation criteria were developed by an expanded membership
of the SOMB that convened for the purpose of explicitly defining
the statutory criteria. The non-SORS criteria may change over time
should policy makers decide to reconsider the current screening
process.
Each of the seven dynamic items in the SOMB Checklist
(three of which are included in the SORS) statistically correlated
with problems in treatment and supervision within the first 12 months
following sentencing. The instrument was developed and tested without
instructions, yet reliability rates for each item were very high.
It has the capacity to be used over time to document an offender's
changes in each of the domains.
Accompanying are the handbooks, instruments, and
additional resource material.
