The STATIC-99 (Static 99) is a risk assessment tool designed to assist
in the prediction of sexual and violent recidivism among adult male sex
offenders. The STATIC-99 is used in most states and is the approved tool
in California and is specifically required for registerable sex offenses
pursuant to California Penal Code Section 290.03-08. In California, The
STATIC-99 is a two page report prepared by the Probation Department prior
to the sentencing of a defendant on a registerable sex crime. It is not
necessary to interview the offender to score the STATIC-99 report.
The STATIC-99 was created by R. Karl Hanson and David Thornton in 1999
and is based on follow-up studies from Canada and the United Kingdom with
a total sample size of 1,301 sexual offenders. The STATIC-99 contains
10 items and produces estimates of future risk based on the number of
risk factors present in any one individual. These risk factors are:
- Presence of prior sexual offenses
- Having committed a current non-sexual violent crime
- Having a history of non-contact sex offenses
- History of non-sexual violence
- The number of prior sentencing dates on the criminal record
- The age of the victim is less than 18 years old
- Having male victims
- Having unrelated victims
- Having victims who are strangers to the defendant
- Having never lived with a lover for two continuous years.
The STATIC-99 report will contain a score that can range from 0 to 12.
A score of 0 to 1 is considered Low Risk. A score of 2 and 3 is Moderate
to Low Risk. A score of 4 and 5 is a Moderate-High Risk. A score of 6
or higher is considered High Risk. The STATIC-99 report is used by the
