Commission on Accreditation for Law Enforcement Agencies, Inc

The Illinois State Police (ISP) is an internationally accredited law enforcement agency. Successful accreditation makes a statement to residents, law enforcement colleagues, and other professionals that ISP meets the very highest standards. The department was first accredited by the Commission on Accreditation for Law Enforcement Agencies, Inc. (CALEA) on June 15, 1986 and has maintained continuous accreditation

CALEA conducts regular, in-depth reviews of agencies in the accreditation process on a four-year cycle. The Commission conducts annual offsite reviews of the department’s files, including a policy and practices review, proofs of compliance, and an annual Agency Status Report. At the end of the four-year cycle, CALEA sends an assessment team to the department for a multi-day onsite inspection, in advance of a full Commission review and reaccreditation. ISP is scheduled for its next site-based assessment January 12-20, 2024.

If you would like to provide comments, commendations, or other information regarding ISP’s quality of service or other information relevant to the accreditation process, please visit the CALEA Accreditation Public Comment Portal (
