The overall re-offense rate for registrants in California is 4.8 percent, according to a recent report issued by Dr. Karl Hanson and colleagues. Of that total, the highest re-offense rate is for transients who lack stable housing.
The report also compared re-offense rates for registrants on parole and probation. The report found that registrants on parole have a higher rate of re-offense (6.1 percent) as compared to those on probation (4.3 percent).
Additional findings in the report include: Hispanics have the lowest rate of re-offense (3.06 percent) as compared to Whites (5.8 percent) and Blacks (6.44 percent). Finally, the report stated that registrants with higher Static-99R scores have a lower rate of re-offense than registrants with lower Static-99 R scores.
The overall purpose of the study which resulted in this report was to “update the predictive validity of Static-99R in California.” According to the report, the Static-99R works well in discriminating between those who re-offend and those who do not and therefore the results “support the continued use of Static-99R in California”.
