Fact Sheets & News

Fact Sheets

• Systematic Reviews of Terrorism Prevention Research Fact Sheet
  DHS S&T, in coordination with the Five Country Research and Development (5RD) Terrorism Prevention Network, identified a need to conduct systematic reviews of prior research and evaluations.
• Terrorism Prevention Grant Evaluation Fact Sheet
  Past local terrorism prevention programs did not undergo robust, independent evaluation. To redress this gap, at the request of the DHS Office of Terrorism Prevention Partnerships (OTPP), the Science and Technology Directorate (S&T) was looked upon to collaborate with subject matter experts in the field to study these programs’ effectiveness in delivering information about what does and does not work in the prevention space.
• Terrorism Prevention Research Fact Sheet
  Terrorism poses a great risk to societies worldwide, and challenges persist in our ability to prevent its threat. The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) directly supports DHS’ terrorism prevention mission, conducting applied research to deliver new capabilities and evaluating program and policy impacts to build the evidence base of what works.

News

• S&T Develops Terrorism Prevention Research Findings Dashboard
  Sept. 28, 2018 -- To counter the continually growing and changing threat of violent extremism, DHS S&T has developed a free and publicly accessible research findings dashboard that hosts more than 1,500 cataloged terrorism prevention and countering violent extremism research documents. This dashboard is an agile, multi‑disciplinary knowledge‑based capability that helps to systematically develop a landscape of the existing research in this topic area across multiple disciplines, including social and behavioral science.
• S&T Develops the First Line of Defense Against Acts of Targeted Violence
  Aug. 28, 2018 -- Since 2010, the U.S. government has invested more than $20 million into understanding all forms of radicalization to violence, as well as effective prevention and intervention measures. Federal agencies such as the DHS Science and Technology Directorate (S&T) and the National Institute of Justice (NIJ) are at the forefront of this work.
• Countering Violent Extremism Program Provides Opportunity for First Responders
