This report estimates whether the Sex Offender Treatment Program (SOTP) reduces recidivism by comparing the recidivism rates of sex offenders who were willing but did not participate in SOTP with those who did participate in the program.
In 1990, Washington became the first state to authorize the release of information regarding sex offenders to the public. Since then, the law has been amended numerous times to expand its application, increase uniformity across counties, and increase citizen access.
This report first examines trends in granting special sex offender sentencing alternatives (SSOSAs). The report then compares recidivism rate trends for those granted a SSOSA to sex offenders not granted a SSOSA.
This report describes how well a “static” risk tool being developed by the Institute for the Department of Corrections predicts recidivism for Washington State sex offenders. This tool is considered static, since it is based solely on demographic and criminal history data that cannot be changed.

This report to the Washington State Legislature summarizes our latest review of evidence-based adult corrections programs. We previously published a review on this topic in 2001. In this study, we update and significantly extend our earlier effort.
We are publishing our current work in two installments. In this preliminary report, we provide a systematic review of the evidence on what works (and what does not) to reduce crime. In a subsequent final report, to be published in October 2006, this analysis will include a benefit-cost estimate for each option.
