Established in 2014 through a partnership between NIJ and the International Association of Chiefs of Police (IACP), the Law Enforcement Advancing Data and Science (LEADS) Program develops the research capacity of mid-career law enforcement personnel who are committed to advancing and integrating science into law enforcement policies and practice. To accomplish this, merit-based scholarships are competitively awarded to mid-rank officers from agencies of any size and executives from small agencies who have effectively infused research into policy development within their agencies.
Research is a valuable tool for law enforcement agencies. This program aims to identify and nurture the next generation of law enforcement leadership through encouraging the use of evidence-based research to advance criminal justice.
NIJ and IACP have built up a strong group of scholars who are committed to using evidence-based research to strengthen the adjudication of law enforcement within their jurisdictions. NIJ and IACP are currently working on techniques to encourage further collaboration between the scholars and to strengthen the program even further moving forward.
As part of the LEADS program, scholarship recipients participate in a number of activities, including:
- Attendance at the IACP Conference.
- Participation in private workshops with NIJ, OJP and IACP leadership.
- Numerous networking activities between the current and incoming classes of scholars.
- An opportunity to network with, and learn from, like-minded officers working towards the common goal of improving law enforcement throughout the nation.
