Certified Fire Investigation Instructor Get Your CFII Certification


The CFII designation recognizes instructors qualified to teach fire and explosion investigation. It provides the dual benefit of establishing a standard for evaluating the qualifications of those teaching fire, arson and explosion investigation, as well as creating a benchmark for instructors who wish to establish their professional credentials.

The CFII program is governed by the official guidelines published in the application packet. This webpage is designed to be a digest of those policies and procedures.
