The Commission on Accreditation for Law Enforcement Agencies was formed in 1979. CALEA established a body of standards designed to increase a law enforcement agency's capabilities to prevent and control crime, increase effectiveness and efficiency in its services, enhance cooperation and coordination with other law enforcement and criminal justice agencies, and increase citizen and employee confidence in the goals, objectives, policies, and practices of the agency. CALEA has developed an accreditation process that provides law enforcement agencies an opportunity to voluntarily demonstrate that they meet a set of professional standards and best police practices.
The District is proud to be the first park district or forest preserve agency in Illinois to meet law enforcement accreditation standards set by CALEA. The District’s Police Department first met this standard in 2001 and achieved four consecutive re-accreditation approvals, with the most recent in 2013. CALEA’s international standards guide the department in delivering quality service while challenging it to continue its commitment to excellence.
