Fire investigators are routinely asked a simple but important question, whether by a supervisor, an insurance adjuster, a defense attorney or a judge: what qualifies you to reach this conclusion? A well-planned path of training, experience and professional certification is the best answer. This guide explains the main standards and credentials that fire investigators in Utah encounter, and how chapter training can help you build toward them. Requirements change periodically, so always confirm details with the credentialing body before you apply.
Start With the Standard: NFPA 1033
NFPA 1033, Standard for Professional Qualifications for Fire Investigator, identifies the minimum job performance requirements (JPRs) for people who serve as fire investigators in both the public and private sectors. It is the benchmark that most certification programs and many courts look to when evaluating an investigator's qualifications.
NFPA 1033 does more than list tasks. It requires investigators to maintain an up-to-date knowledge, beyond the high school level, of a list of technical topics that includes fire science, fire chemistry, thermodynamics, fire dynamics, explosion dynamics, fire investigation methodology, evidence documentation, collection and preservation, hazardous materials, fire protection systems, and electricity and electrical systems, among others. It also expects investigators to remain current through formal education courses, workshops, seminars and professional publications. That continuing education expectation is one of the reasons chapter conferences matter.
The job performance requirements themselves cover areas such as employing the scientific method, completing a site safety assessment, examining the scene, documenting it, collecting and preserving evidence, conducting interviews, analyzing the incident and presenting findings. The companion document, NFPA 921, Guide for Fire and Explosion Investigations, explains how to carry out that work; see our article on NFPA 921 and the scientific method.
IAAI Professional Credentials
The International Association of Arson Investigators offers a family of credentials designed for different roles. The IAAI announced updates to its certification program in 2025, so check the current requirements on the IAAI website (firearson.com) before planning your application.
IAAI-CFI (Certified Fire Investigator)
The IAAI-CFI is intended for experienced investigators. Certification is earned through application, evaluation and examination, and historically has required several years of fire investigation experience consistent with NFPA 1033 together with a substantial, documented training history. Because of those prerequisites, many investigators treat the CFI as a medium-term career goal and plan their training around it.
IAAI-FIT (Fire Investigation Technician)
The IAAI-FIT credential is designed for people who perform fire investigation functions but may not have the training and experience, or the need, to qualify for the CFI. It is a practical milestone for company officers, newer investigators and law enforcement officers who assist at fire scenes.
IAAI-ECT (Evidence Collection Technician)
The IAAI-ECT focuses on the documentation, collection and preservation of fire scene evidence, and includes a practical examination component. It pairs well with the skills described in our evidence collection guide.
Specialty credentials
The IAAI also lists an instructor credential (IAAI-CI) and specialty credentials for motor vehicle fires, IAAI-(V), and marine fires, IAAI-(M). Investigators who handle many vehicle cases may find the vehicle specialty useful; see vehicle fire investigation basics.
Utah Fire Service Certification
In Utah, the Utah Fire Service Certification System is administered by the Utah Fire and Rescue Academy (UFRA) at Utah Valley University. The system is based on professional job performance standards from NFPA and NWCG, and certification exams are administered by authorized testers after training. UFRA publishes a Fire Investigator certification standard, and its fire investigator coursework is described as meeting the requirements of NFPA 1033. For many public-sector investigators, state certification is a logical first credential, and the academy is listed on our Links page.
Wildland Fire Investigation Qualifications
Wildland fires are investigated under a different framework. The National Wildfire Coordinating Group (NWCG) publishes the Guide to Wildland Fire Origin and Cause Determination (PMS 412), and the NWCG course FI-210, Wildland Fire Origin and Cause Determination, is the primary way its principles are taught to wildland fire investigators. If your jurisdiction includes wildland-urban interface or rangeland, read our introduction to wildland fire investigation.
Other Professional Credentials
Some investigators, particularly in the private sector, also hold credentials from other organizations, such as the National Association of Fire Investigators (NAFI). Whichever credentials you pursue, make sure they are relevant to your role, recognized by the people who rely on your work and supported by training you can document.
Building Your Training Record
Most credentials require documented training. A few habits make that much easier:
- Keep a training log. Record the course title, provider, dates, hours, instructor and whether the course was tested. Save certificates in one place.
- Use online training strategically. CFITrainer.Net, the IAAI's online learning network, offers more than 90 modules on topics from fire dynamics and investigation fundamentals to electrical systems, vehicle fires and witness interviewing. According to the site, much of this training is supported by a FEMA Fire Prevention and Safety grant. It is also listed on our Links page.
- Attend conferences. Multi-day events such as the Utah IAAI annual conference combine classroom hours with practical exercises like burn cells and electrical demonstrations.
- Document your casework. Many credentials ask about the number and type of investigations you have conducted. Keep an accurate case list with dates, incident types and your role.
- Read the literature. NFPA 1033 expects investigators to stay current through professional publications and journals.
A Practical Five-Step Plan
- Read NFPA 1033 and identify the job performance requirements that apply to your current duties.
- Complete an entry-level investigator course and obtain the credential that fits your role, such as state certification or the IAAI-FIT.
- Add specialized training in evidence collection, electrical fires, fire dynamics and interviewing.
- Build your case experience under the guidance of experienced investigators, and ask for peer review of your reports.
- When you meet the prerequisites, apply for an advanced credential such as the IAAI-CFI, and keep renewing through continuing education.
Why Credentials Matter in Court
Certification does not by itself make an opinion admissible or correct, but it helps demonstrate that you have been trained to apply accepted methodology. Your credentials, training log and experience will usually be summarized in your curriculum vitae, which is often the first document an attorney examines. Our article on expert testimony and CVs explains how to present them accurately.
Train With the Utah Chapter
The Utah Chapter IAAI exists to provide quality training and networking for fire investigators and allied professionals. Check the Training page for the next conference, explore more investigator resources, and if you are not yet a member, read how to join the chapter.
