International Association of Chiefs of Police
The International Association of Chiefs of Police (IACP) was founded in Chicago in 1893 as the National Chiefs of Police Union. The primary goal of this organization was to apprehend and return criminals who had fled the agency jurisdictions in which they were wanted. The organization has expanded over the years with the goals of advancing the science and art of police work, promoting improved practices throughout the law enforcement community and foster cooperation and information exchange among police administrators.
IACP's stated mission includes to:
- Advance the science and art of police services;
- Develop and disseminate improved administrative, technical and operational practices and promote their use in police work;
- Foster police cooperation and the exchange of information and experience among police administrators throughout the world;
- Bring about recruitment and training in the police profession of qualified persons
- Encourage adherence of all police officers to high professional standards of performance and conduct.
The IACP helped to develop and/or promote many tools currently used by law enforcement agencies. These tools include the use of fingerprints, Uniform Crime Reports and the Federal Bureau of Investigation's National Academy for state and local police.
The United Nations granted a Consultative Status to the IACP in the 1970s due to the IACPs work in several UN member nations. Also in the 1970s, the IACP developed a national bomb data center and turned this over to the FBI. See also U.S. Bomb Data Center.
Along with other activities, the IACP publishes Police Chief Magazine.
Psychological Services Section 
There is a special section of the International Association of Chiefs of Police called the Psychological Services Section. The Psychological Services Section is composed of recognized specialists in this field, both those employed by larger department and independent consultants. The section has been in operation since 1986 and now consists of over one hundred members, primarily from the United States. The section publishes guidelines for various types of police psychological services.

Its first president, Richard Sylvester, chief of the Washington D.C. P.D., was widely regarded as the father of police professionalism.
