Static-99/Static-99R

Overview

Static-99 is a ten item actuarial assessment instrument created by R. Karl Hanson, Ph.D. and David Thornton, Ph.D. for use with adult male sexual offenders who are at least 18 year of age at time of release to the community. In 2012, the age item for the scale was updated, creating Static-99R. Static-99/R is the most widely used sex offender risk assessment instrument in the world, and is extensively used in the United States, Canada, the United Kingdom, Australia, and many European nations.

This site is dedicated to the community of Static-99R users, and governed by an Advisory Board whose members approve and submit content, and rotate responsibility for answering Static-99R coding questions. Our intent is to provide useful information in a timely manner, and to promote best practices in sexual offender assessment among professionals who routinely use the instrument.

Coding questions may be submitted to Dr. Yolanda Fernandez (staticquestions@gmail.com); please consult the coding manual and FAQs prior to submission. Routine questions will be answered by the Site Manager, who has the full confidence of the Static-99R developers.  Complex questions will be referred by the Site Manager to the Advisory Board for discussion and a response will be forwarded to the requestor as quickly as possible (in most cases within 5 business days).
Veuillez envoyer les questions en français à Dr. Claire Ducro (claire.ducro@crds.be).

Documents

Please note that there is a new 2016 version of the coding manual, which should replace previous versions of the manual. In assessment reports, we recommend evaluators report which version of the coding manual was used.

Translations of the coding manual follow the 2003 version (in the archived section below), and should eventually be replaced, following the new coding rules.

Current users of Static-99R should receive training on the manual updates before using it in practice. See "Training" tab of this website for more information.



We recommend that users obtain training from a certified trainer before scoring real cases on Static-99R or Static-2002R.

We also recommend that anyone trained on the 2003 Coding Manual (or earlier versions) obtain training on the new 2016 coding manual. See below ("Static-99R Training") for more information.


Static-2002R and BARR-2002R Training

BARR-2002R is a scale that includes 6 items from Static-2002R and can be used to comment on risk for violent recidivism. Static-2002R training automatically includes BARR-2002R trianing.

    Static-99R Training

    *IMPORTANT 2016 UPDATES*

    We recommend anyone using Static-99R obtain training from a certified trainer. Training is generally a full day, and can be online or in person, but should involve opportunities for interaction (i.e., Q&A) and supervised practice with example cases. With the new 2016 coding manual, we ask for your patience as we transition our training processes. The list of certified trainers (below) includes all those certified on the pre-2016 version of the coding manual. We are preparing a re-certification exam to ensure all our existing trainers are up-to-date on the new manual. If you are contacting a trainer or online course provider from the information below, please ask them if they are certified on the 2016 version of the coding manual. As of October 2016, trainers who are re-certified include Amy Phenix, Yolanda Fernandez, Andrew Harris, Maaike Helmus, Karl Hanson, and David Thornton. We expect many more names will follow in November/December 2016.

    If you have already been trained in Static-99 or Static-99R prior to the release of the 2016 version of the coding manual, we strongly recommend you obtain training on the updates to this coding manual, as there are many non-trivial changes (some of which may be missed if not pointed out by a trainer). This does not require a new full-day training on the scale (although in some cases a full training may be helpful as a refresher). Minimally, to be consistent with our recommendation, we suggest a half-day training specifically highlighting what is new in the coding manual (as well as reading the new manual in full, and referring to it often). Such a training (called a Booster training) is offered online on-demand by the Global Institute of Forensic Research for $65, with availability for some CE credits (see below). You can also obtain a similar training from a certified Static-99R trainer (see note above that this trainer should be re-certified on the new manual). Additional training opportunities ( e.g., with practice cases) may be helpful in consolidating and applying the new material, but should be considered optional.

    Static-2002/R

    We recommend evaluators use Static-2002R instead of Static-2002.


    Static-2002R

    Note that Static-99/R training is not sufficient to score Static-2002/R. We recommend that evaluators obtain Static-2002/R training before using the scale.

    • Data Collection/Coding Standards - coming soon

     

    Current Norms

    The developers of Static-99 recommend that evaluators use Static-99R instead of Static-99. Note that we no longer endorse reporting violent recidivism estimates for Static-99R. To comment on risk for violent or any recidivism among sex offenders, we recommend using BARR-2002R (training on BARR-2002R is incorporated in Static-2002R training).

    The Evaluator Workbook includes templates for reporting Static-99R and Static-2002R scores. These are only examples, and evaluators should use their professional judgement concerning the preferred wording, taking into consideration the purpose of the assessment and the expected readers of the report. Evaluators should feel free to download and edit the WORD document as they see fit

    Static-99 Norms

    Note that the revised Static-99 norms contain fewer samples than the Static-99R norms. We do not plan to continue research on the Static-99 norms given that we recommend evaluators use the Static-99R.

    Disclaimer: The content of the STATIC-99 website (including the scoring rules and responses to questions) is accurate according to the opinions of the authors of the coding rules. The information and directions may or may not apply to specific individuals considered for assessment using the STATIC-99. Determination of appropriate application and scoring of the STATIC-99 to specific cases and in specific jurisdictions requires the judgment of an evaluator trained in the applied use of the STATIC-99.
