Assessment Tools for Sexual Recidivism Risk
A practical guide to four complementary toolsUnderstand what Static-99R, Static-2002R, STABLE-2007, and ACUTE-2007 contribute—and why structured risk assessment still requires trained, contextual professional judgement.
The series
Different information for different timeframes
These four tools organize different kinds of information about sexual recidivism risk. Static-99R and Static-2002R provide long-term baselines from historical factors. STABLE-2007 considers risk-relevant patterns that can change over months or years. ACUTE-2007 supports attention to rapidly changing circumstances during supervision.
No score tells the whole story. Each tool has a defined purpose, population, evidence base, and set of limits. Responsible use means applying current guidance, combining information appropriately, and communicating uncertainty clearly.

Four tools, one connected framework
Start with the tool that matches your question, then use the navigator on every page to move through the series.
Static-99R
A 10-item actuarial tool that provides a long-term baseline estimate for adult males with a charge, conviction, or equivalent for a sexually motivated offence.
Static-2002R
A static actuarial tool that organizes historical information into a long-term baseline for sexual recidivism. Its related BARR-2002R subset addresses violent and general recidivism without requiring additional information.
STABLE-2007
A structured measure of risk-relevant propensities that can change over time and can inform treatment and supervision needs.
ACUTE-2007
A short-term dynamic measure for rapidly changing situational factors considered during community supervision.
Plain-language guide
Baseline, stable, and acute are not interchangeable
Baseline: the long view
Static tools use defined historical information that does not change. They offer a long-term starting point, not a complete explanation of a person or future outcome.
Stable: patterns over time
Stable dynamic factors may shift over months or years. They help organize information relevant to intervention, progress, and ongoing management.
Acute: what can change quickly
Acute factors can shift over days or weeks. They support structured monitoring in the contexts for which the tool was developed.
