Project I-CLEAR Evaluation

 While advances in information technology (IT) have revolutionized how the world works and
communicates, IT is still in the take-off stage in the criminal justice world. Programs like the
highly publicized CompStat system in New York are starting to show law enforcement officials
the effectiveness of data-driven policing, but adoption of innovative technology in the criminal
justice arena continues to creep along. Under the direction of Jill Dubois, PR conducted an
evaluation of the Chicago Police Department’s ongoing IT developments, and of  I-CLEAR
(Illinois Citizen Law Enforcement Analysis and Reporting), an innovative state-wide criminal
justice data integration project. Launched jointly by the Illinois State Police and the Chicago
Police Department (CPD). I-CLEAR led to in the availability of a uniform incident-reporting
system and data sharing among all law enforcement agencies throughout Illinois. The I-
CLEAR evaluation was supported by a grant from the Illinois Criminal Justice Information

 I-CLEAR is the evolution of an ambitious data-sharing project begun by the CPD in
partnership with Oracle Corporation. More than five years ago, the CPD created its “data
warehouse,” a queriable repository of over five million arrest records drawing from multiple
data sources that is updated daily. The Chicago Police Department first offered data
warehouse access to jurisdictions in Chicago’s collar counties and eventually throughout the
state. A study of this regional effort was conducted by IPR researchers Susan Hartnett and
Wesley G. Skogan, and a reprint of an article reporting the findings can be found on this web

 The I-CLEAR evaluation had seven goals: to identify and monitor key policy, managerial,
technical, and funding issues; to monitor how effective the project’s many collaborators were
in working together; to pinpoint needs involving training, technical capacity, data collection
and security, and access; to track the levels of agency involvement in the participatory
program; to identify innovative uses of I-CLEAR; to describe its impact on the efficiency and
effectiveness of the state’s criminal justice process; and to describe the implementation
process and functioning of this cutting-edge project to the national criminal justice
community. The project started in May 2005, and included stakeholder and feedback
interviews, a statewide survey of more than 360 agencies, site observations, observations of
all major planning and coordinating meetings, and statistical modeling.
