This Annual Report informs the President and Congress of National Institute of Justice (NIJ) activities as required by Title I of the Omnibus Crime Control and Safe Streets Act of 1968 and Title II of the Homeland Security Act of 2002. NIJ initiated two new areas of research in Fiscal Year 2017 to support law enforcement: (1) officer safety, health, and wellness and (2) officer decision-making. It also conducted a Real-Time Crime Forecasting Challenge to encourage data scientists across all scientific disciplines to foster innovation in forecasting methods. NIJ released many publications in FY 2017, including strategic research plans on policing and the Sentinel Events Initiative as well as National Best Practices for Sexual Assault Kits: A Multidisciplinary Approach. The latter was a result of recommendations by a multidisciplinary working group created to address the Sexual Assault Forensic Evidence Reporting Act of 2013. During FY 2017, NIJ continued to fund research projects relevant to the needs of the field.
