The Extremist Risk Intervention Scale

The Extremist Risk Intervention Scale (ERIS) is a practical scoring tool useful for those on Behavioral Intervention Teams, law enforcement, and counter-terrorism teams to assess and intervene with extremist and terrorist violence.

The Extremist Risk Intervention Scale (ERIS) is a researched-based expert system useful for assessing individuals during an in-person interview who have expressed a hardened perspective (typically on religious, political or social justice issues) who then feel justified acting violently to others. Those using the ERIS are recommended to have completed a NaBITA course on the instrument to better understand the creation, administration and interpretation of the measure. The tool should be used in conjunction with further training and study. A starting place for this would be reading this article, this scoring sheet or contacting the author Brian Van Brunt, at the bottom of the page.

Note: Dangerousness and violence, from a student , faculty, or staff member is difficult, if not impossible, to accurately predict. This training topic offers research-based techniques and theories to provide a foundational understanding and improved awareness of the potential risk. The training or tool should not be seen as a guarantee or offer any assurance that violence will be prevented.
