National Criminal History Improvement Program (NCHIP)

The extent to which criminal history records are complete, accurate, and timely. In addition, accessibility sometimes is considered a data quality factor. The key concern in data quality is the completeness of records and the extent to which records include dispositions as well as arrest and charge information. Other concerns include the timeliness of data reporting to state and federal repositories, the timeliness of data entry by the repositories, the readability of criminal history records, and the ability to have access to the records when necessary.

A record (or the system maintaining such records) that includes individual identifiers and describes an individual's arrests and subsequent dispositions. Criminal history records do not include intelligence or investigative data or sociological data, such as drug use history. CHRI systems usually include information on juveniles if they are tried as adults in criminal courts. Most, however, do not include data describing involvement of an individual in the juvenile justice system. All data in CHRI systems are usually backed by fingerprints of the record subjects to provide positive identification. State legislation varies concerning disclosure of criminal history records for noncriminal justice purposes.

Successor to the National Crime Information Center (NCIC) APB, the CJIS APB is comprised of 30 criminal justice officials who provide policy input to guide the Federal Bureau of Investigation (FBI) in the administration of its CJIS Division. The CJIS Division administers the NCIC, the Uniform Crime Reporting (UCR) Program, the Integrated Automated Fingerprint Identification System (IAFIS), and other information system programs determined by the FBI director to have some relationship with these programs.

The database (or the agency housing the database) that maintains criminal history records on all state offenders. Records include fingerprint files and files containing identification segments and notations of arrests and dispositions. The central repository is generally responsible for state-level identification of arrestees, and commonly serves as the central control terminal for contact with FBI record systems. Inquiries from local agencies for a national record check (for criminal justice or firearm check purposes) are routed to the FBI via the central repository. Although usually housed in the Department of Public Safety, the central repository may be maintained in some states by the state police or some other state agency.
