Advancing Justice Through Science

Learn more about NIJ

NIJ is seeking input as we develop a Public Access Plan to increase access to publications and data resulting from NIJ-funded research. Ensuring broad access to the products of NIJ-sponsored research is critical to achieving our mission to provide evidence, data, and tools to inform criminal and juvenile justice communities, victims services providers, and the public. The goals of the plan are to expand timely access to the results of NIJ-funded research and the data underpinning it. Facilitating access to both publications and data without barriers increases transparency and reproducibility. This has the potential to accelerate new discoveries and practical applications and contribute to evidence-based changes in policy and practice, which is all in the public interest. 

See the Federal Register announcement for more details and how to provide comments, which are due by 5 pm ET on November 29, 2024. 

Webinar on Expanding Public Access to NIJ-Funded Research

NIJ is seeking input from grantees, criminal justice practitioners, academics, publishers, data repositories, nonprofits, and the public as we develop a plan to increase access to the publications and data resulting from NIJ-funded research. The goal of increased transparency has the potential to accelerate new discoveries and contribute to evidence-based changes in policy and practice. Comments are due November 29, 2024. 

New Projects to Advance Forensic Science

NIJ announced $13.6 million in new funding to support 24 projects under the “FY24 Research and Development in Forensic Science for Criminal Justice Purposes” solicitation. Through this program, NIJ continues to advance the speed, accuracy, and reliability of forensic analysis, which bolsters the administration of justice.

Screening for Fentanyl in Mandatory Testing

Given the soaring rates of opioid-related overdoses, fueled in large part by the introduction of highly potent fentanyl and related drugs, it’s crucial that public health and criminal justice officials have accurate drug prevalence data. A new article breaks down NIJ-funded research detecting fentanyl use among people under court-ordered mandatory drug testing.

Term of the Month — Ballistic Resistance

Last November, NIJ issued updates for testing ballistic resistant body armor and ballistic threat levels. These new specifications include improved testing methods for armor designed for women, additional requirements for hard and soft armor components, and ballistic threat standards for varying ammunition types. Learn about the science behind how NIJ’s Compliance Testing Program develops and tests body armor standards for ballistic resistance.

Criminal Justice Data Archives

The National Archive of Criminal Justice Data archives data on crime and justice and contains data from over 2,700 curated studies or statistical data series. The website is home to several large-scale datasets, including the National Crime Victimization Survey, FBI's Uniform Crime Reports and National Incident-Based Reporting System, and the Project on Human Development in Chicago Neighborhoods.
