Sex offender risk assessment is a critical aspect of the criminal justice system in the United States. It plays a pivotal role in determining the potential risk that a convicted sex offender poses to the community and helps guide decisions related to sentencing, treatment, and supervision. One of the most common risk assessment tools used in the United States is the Static-99R. In this blog post, we will delve into what the Static-99R is, why it is widely used, and its impact on the management of sex offenders.

What is the Static-99R?

The Static-99R is an actuarial risk assessment tool designed to evaluate the likelihood of sexual reoffending among male sex offenders. An actuarial risk assessment test means the test uses a set of static factors which are factors that cannot be changed, such as age at first offense and the number of prior sexual offenses. Developed by R. Karl Hanson and David Thornton, Static-99R is an updated version of the original Static-99, and has been widely adopted in the United States and other countries.

The R in Static-99R stands for revised, as this version incorporates several modifications and improvements over its predecessor, Static-99. The primary objective of the Static-99R is to provide a standardized and evidence-based approach to assess the risk of sexual recidivism, helping legal professionals make informed decisions regarding sentencing, parole, and post-release supervision.

How Does the Static-99R Work?

The Static-99R assesses the risk of sexual reoffending by considering a set of specific risk factors, each assigned a weighted score. These risk factors include:

1. Age at release: Younger offenders tend to be at a higher risk of reoffending.
2. Prior sexual offenses: Individuals with a history of previous sexual offenses are considered a greater risk.
3. Relationships: Offenders who are in stable relationships or living with a partner may have a reduced risk.
4. Victim characteristics: Offenders who have committed sexual offenses against strangers or unrelated victims may be at a higher risk.
5. Offense history: The type and severity of previous offenses are taken into account.
6. Non-contact sexual offenses: Offenders who have engaged in non-contact offenses, such as exhibitionism, may have a lower risk.

This categorization helps legal professionals and treatment providers make decisions about sentencing, supervision, and the need for sex offender treatment programs.

Why is the Static-99R Widely Used?

Several factors contribute to the widespread adoption of the Static-99R in the United States:

1. Empirical Validity: The Static-99R is grounded in research and has demonstrated good predictive accuracy in assessing the risk of sexual reoffending. Its reliability and validity have been extensively studied and validated through empirical research.
2. Standardization: The tool provides a standardized method for assessing risk, reducing subjectivity in decision-making processes. The consistency is essential for fairness and equity within the criminal justice system.
3. Ease of Use: The Static-99R is relatively easy to administer, making it accessible to professionals within the criminal justice system, including parole officers, psychologists, and judges. It is also available in many different languages, making it a practical tool for use in a variety of settings.
4. Legally Accepted: Courts in many states across the United States have recognized the validity and utility of the Static-99R in making decisions related to sentencing, parole, and post-release supervision.
5. Continual Updates: The revised nature of the Static-99R means that it evolves with ongoing research, incorporating the latest findings into its risk assessment process.
6. International Acceptance: Apart from the United States, the Static-99R is also used in numerous other countries, contributing to its international acceptance and recognition.

Courtroom Admissibility of Static-99R Results

Numerous state courts have held sex-offender risk assessment results based in part on actuarial testing, like the Static-99R, is generally accepted within the scientific community and sufficiently reliable to be admissible when considering the future risk of a sex offender to reoffend. Such states include: Arizona, California, Florida, Illinois, Iowa, Kansas, Massachusetts, Minnesota, Montana, Missouri, Nebraska, New Jersey, New York, North Dakota, Ohio, Oregon, South Carolina, Texas, Washington and Wisconsin.

Static-99R Impact on Sex Offender Management

The Static-99R has a profound impact on the management of sex offenders in the United States. Here are some key ways in which it influences the criminal justice system:

1. Sentencing: Judges often consider Static-99R scores when determining the length of sentences for sex offenders. Those assessed as higher risk may receive longer sentences to protect the community.
2. Parole Decisions: Parole boards use Static-99R scores to determine whether an offender is eligible for for parole and, if so, the level of supervision required upon release.
3. Treatment Planning: Sex offender treatment programs can be tailored to individual risk levels, ensuring that higher-risk offenders receive more intensive interventions.
4. Community Notification: In some cases, Static-99R scores may be used to inform the community about the presence of high-risk sex offenders, promoting public safety.
5. Research and Evaluation: The Static-99R contributes to ongoing research in the field of sex offender risk assessment and recidivism, allowing for data-driven improvements in the criminal justice system.

What is the Accuracy of Static-99R?

The Static-99R has been shown to be a reliable and accurate predictor of sexual recidivism. In a meta-analysis of 130 studies, the Static-99R was found to have an overall accuracy rate of 79%. That means that the Static-99R correctly predicted whether or not a sex offender would reoffend 79% of the time.

Criticisms and Controversies:

Despite its widespread use and acceptance, the Static-99R is not without its criticisms and controversies. Some of the key concerns include:

1. Exclusivity to Male Offenders: The Static-99R was primarily developed for adult male sex offenders, limiting its applicability to other populations.
2. Focus on Static Factors: Critics argue that the tool places too much emphasis on static factors (historical data) and does not adequately consider dynamic factors that may change over time.
3. Cultural Bias: Some researchers suggest that the Static-99R may have cultural biases, potentially leading to disparities in risk assessment for different racial or ethnic groups.
4. Overreliance on Scores: There is a risk of overreliance on Static-99R scores, with professionals making decisions solely based on the numerical result rather than considering other relevant factors.
5. Limited Predictive Power: While the Static-99R is a valuable tool, it is not infallible, and there are instances of individuals with low scores and vice versa.

My Final Thoughts

The Static-99R is undoubtedly the most common risk assessment tool for sex offenders in the United States. Its use is deeply ingrained in the criminal justice system, guiding decisions related to sentencing, parole, and post-release supervision. While it has its strengths and limitations, its empirical validity and standardization make it an essential tool for ensuring public safety and managing sex offenders effectively. However, its crucial to continue evaluating and refining such tools to address concerns and adapt to evolving research in the field of sex offender risk assessment.
