LECS data are primarily collected through BJS' core law enforcement data collection programs: the Law Enforcement Management and Administrative Statistics (LEMAS) core and supplement surveys and the Census of State and Local Law Enforcement Agencies (CSLLEA).

Through the Law Enforcement Core Statistics Program (LECS), BJS combines these collections into a cohesive law enforcement collection program and reshapes their content to focus on agency performance as well as contemporary topics related to agency staffing, regulations, and policies. By redesigning the component collections of LECS, BJS will be able to provide detailed information about LEA performance that aligns these collections with an ongoing national discussion about the need for new measures and metrics for law enforcement agencies.

BJS is administering the Law Enforcement Management and Administrative Statistics (LEMAS) Post-Academy Training and Officer Wellness (PATOW) survey. The LEMAS PATOW survey is an important part of BJS’s Law Enforcement Core Statistics (LECS) program, which includes law enforcement agency surveys conducted by BJS to understand personnel, policies, and procedures of state, local, and tribal law enforcement agencies in the United States. The LEMAS PATOW survey includes questions about resources provided to staff with a focus on post-academy training and wellness services. Together, the LECS surveys provide key nationally representative data on personnel, policies, and agency activities at local, county, state and national levels. Selected agencies will receive a notice this Fall or early next year when the survey is available.
