Fire Investigator Certification

Whether you hope to solve arson cases or aspire for a satisfying career in public safety, earning a Fire Investigator certificate can advance your skills and keep you up to date on the latest fire investigation techniques.

Do I need Fire Investigator certification?

Becoming a Fire Investigator requires experience, dedication, and education. Certification may be a requirement for some positions. Beyond that, this credential will serve you well when it’s time for promotions, raises, and other opportunities in the workplace.


There are three levels of certification offered through the National Association of Fire Investigators. The most basic Fire Investigator certificate requires you to complete a 100-question, multiple-choice exam. You have two hours to complete the test, and must earn a passing grade of 75 percent or higher.

If you fail to achieve this score, you must wait six months before retesting. Once you pass, you’ll hold the title of Certified Fire and Explosion Investigator (CFEI).

If you wish to continue your fire investigation training, you can enroll in an advanced course. You have a couple of choices.

The first is a one-day course that teaches you how to convey your knowledge to others. You must hold the CFEI as a prerequisite. Following the course, you can apply for and complete your Certified Fire Investigator Instructor (CFII) exam.

The second is a four-day, 36-hour class that enhances your fire investigation skills. Upon completion, you’ll test to earn your accreditation as a Certified Vehicle Fire Investigator (CVFI).
