Unit 1 Slide Deck: Police-Led Field Experiments: Lessons from the NIJ’s LEADS Scholars Program
Unit 2 Recording: Police-Led Field Experiments

A police sergeant on the east coast and a police lieutenant on the west coast describe studies they have recently completed in their mid-sized departments to test the effectiveness of patrol techniques. Their studies, which were field experiments in the vein of rapid research, including random assignment, not only produced information of practical value but also demonstrated an important element of evidence-based policing — systematically testing what you do to determine how well it works — not because you got a grant that required an evaluation, but because it is the logical and rational thing to do. They have even taken the next step of replication, to see whether the results from a study in one department are reproducible in a different jurisdiction.

Attendees will:

  • Gain an appreciation for innovation in policing, as well as the need to test current practices.
  • Learn about field experiments and different methodological approaches to study design.
  • Learn how to gain buy-in from stakeholders at various levels of the organization including collective bargaining units – lessons learned will also be discussed.
  • Learn about different avenues to find free partnerships that will assist agencies with research design and statistical analysis


Other Webinars in this Series are:

March 28: Implementing Evidence-Based Policing

April 24: Contemporary Police Responses to Addiction

August 1: Reducing Traffic Fatalities in Urban & Rural Areas


As a program supported by the National Institute of Justice, The LEADS Scholars program grew out of a desire to support and develop the next generation of law enforcement leadership in America. The LEADS Scholars program offers immeasurable benefit both to both scholars and their agencies. With NIJ advisory and research support, LEADS scholars have designed and conducted studies to help their agencies identify and solve major challenges through research. The program provides officers with professional development, mentorship, and networking opportunities, and NIJ provides editorial support in publishing and promoting research.




This webinar has been presented in partnership with the International Association of Law Enforcement Planners. IALEP is a member-governed organization for people working in, or interested in, planning, policy, budget, performance measurement, analysis, research, and other related functions for criminal justice agencies.




Audience Comments:

  • “Excellent review of studies in a relatively short amount of time. Bravo!” — Adam
  • “Practitioners are in the field, conducting the research and gathering the data while employed as active law enforcement brings credibility and buy-in academically.” — Brian
  • “Great information about the LEADS program. I want to learn more and work towards implementing some research projects at my agency.” — Bill
  • “The insight offered by the two law enforcement officers as researchers on determining the effects of a specific action aimed at crime deterrence. We try varying strategies regularly in policing communities, but we don’t stop to ensure they are controlled experiments as we strive to determine if the strategy was, or was not, effective or successful. This presentation planted the seed for more experimentation and research in our policing efforts.” — Silver
  • “The webinar was excellent. This is a wonderful thing you are doing with the webinar series. I appreciate opportunities like this as I continue to grow and improve how we serve our community. I valued everything that you’re researched provided and I looked forward to being part of the next one. Thank you!” — Theresa
