About NDI

The purpose of the National Decertification Index (NDI) is to serve as a national registry of certificate or license revocation actions relating to officer misconduct. The records contained in the NDI are provided by participating state government agencies and should be verified with the contributing authority. Inclusion in the database does not necessarily preclude any individual from appointment as an officer.

For additional information, contact Mike Becar, Project Director.

NDI Brochure

The NDI currently contains 30518 actions reported by 45 certifying agencies.

Integrity Bulletins


Several states make the outcomes of police officer investigations a matter of public record.  In some cases these reports may provide you with additional information about actions recorded in the NDI database.
