Fire investigators must have experience as a firefighter, a position which requires a high school diploma. Many firefighters also complete a postsecondary program for EMTs. Your employer may prefer that their investigators have an associate's or bachelor's degree in fire science, engineering or chemistry.

State regulations typically require some combination of classroom and on-the-job training for fire investigators. Fire and police academies, the ATF, FBI, as well as organisations like National Fire Academy and International Association of Arson Investigators, offer training programmes in investigation. Completion of classroom coursework can take several months.

Fire investigators may also be required to achieve and maintain certification, typically according to standards set by the National Fire Protection Association (NFPA). Check with your local government to verify requirements. You may also acquire certification from national organisations like the National Association of Fire Investigators (NAFI).

Career progression

Your first job in fire investigation may have a probationary period. As you gain more knowledge, experience and certifications, you will be eligible for roles with more responsibility. Transitioning to investigator jobs in larger cities or with federal agencies can bring on bigger challenges.

Experience and additional education can lead to supervisory or instructor roles. You may also find success by specialising as a certified arson investigator, risk analyst for insurance companies, or a consultant on fire prevention and suppression in the building trades.
