The Estimate of Risk of Adolescent Sexual Offense Recidivism (The ERASOR: Worling & Curwen, 2001) is an empirically-guided checklist to assist evaluators to estimate the short-term risk of a sexual reoffense for youth aged 12-18. The ERASOR was designed as a single-scale instrument, and the 25 risk factors that are evaluated fall under 5 headings: Sexual Interests, Attitudes, and Behaviors, Historical Sexual Assaults, Psychosocial Functioning, Family/Environmental Functioning, and Treatment. All risk factors are coded as either Present,Possibly/Present, Present, Not Present, or Unknown, and the coding manual outlines the specific coding criteria—in addition to the research/clinical support—for each factor.
The ERASOR is currently in widespread use throughout Canada and the U.S.A (McGrath, Cumming, Burchard, Zeoli, & Ellerby, 2010), and it is also being used in a number of other countries.
8-hour, web-based training by the author of the ERASOR will provide step-by-step coding suggestions and practice regarding the the use of the ERASOR--in addition to an overview of the research support.

Please also note the new DASH-13, under the Protective Factors tab. This is a checklist of possible protective factors intended to enhance comprehensive assessments by providing information regarding strengths.
