Arson Investigation Course: Which Ones Will Actually Admit You

An arson investigation course teaches you to determine a fire's origin and cause (where it started and what caused it) and to build evidence for a criminal case. A credential is a separate award, such as IAAI-FIT, IAAI-CFI or NAFI CFEI, that certifies you have done that work for a set period.

Three terms recur:

Very few. This page compares ten pathways: the state, federal and association options a civilian is most likely to find in October 2026. Three require a badge or fire-service certification, one is aimed at law enforcement investigators but lists no prerequisite, one is limited to members of public safety agencies, three are credentials that require documented experience, and two are open to anyone who registers or pays.

A peace officer, in the table below, is a sworn, licensed law enforcement officer.

Learningshopusa publishes this page. We do not sell an arson investigation course, so none of the courses above are ours.

Cost per hour (our arithmetic, using the prices above as of October 2026):

• Florida in-state: $75 ÷ 45 hours = $1.67 an hour.
• Florida out-of-state: $185 ÷ 45 hours = $4.11 an hour.
• LLRMI: $250 ÷ 20 hours = $12.50 an hour.
• National Fire Academy and CFITrainer.net: no tuition.

The cheapest classes are the ones reserved for people with an agency behind them. Anyone without a sponsor pays the highest hourly rate, or starts with the free option.

A class adds hours to your record, but the credentials employers recognize also require years of documented work. IAAI-FIT needs 54 tested hours and 18 months of experience. IAAI-CFI needs 400 hours and five years.

The CFI hours break down as 40 (IAAI Fundamentals of Fire Investigation) plus 28 (CFITrainer.net required courses) plus 332 (additional courses aligned to NFPA 1033), which totals 400. That is ten 40-hour weeks of training, about 7.4 times the FIT requirement of 54 hours. CFI applicants must also submit job performance requirement check sheets (the tasks NFPA 1033 expects an investigator to perform), signed by an IAAI-approved evaluator, and recertify every five years with 100 tested hours, an average of 20 a year (sources: IAAI-FIT, IAAI-CFI).

BLS says fire inspectors and investigators typically need a high school diploma and prior experience as a firefighter or in a related field, then receive on-the-job training. It projects 6% employment growth from 2025 to 2035, with about 1,900 openings a year, mostly to replace workers who change occupations or leave the labor force (BLS).

Our recommendation: if you aim at insurance or private origin-and-cause work, plan for the CFI or CFEI credential and several years of documented fire-scene work, not for a single course. The work record is the slow part. Start it first.

Run three tests, in order. Each has a clear pass and a clear fail, and together they show which courses are open to you.

Do you hold a peace officer license, or a firefighter or fire inspector certification?

Pass: you hold a current license or certification. The state courses and certificates in the table above are open to you. Fail: they are closed. Florida's BFST407 and Texas's arson certificate both state the requirement, so do not enroll expecting an exception.

Can you document 18 months of fire investigation work and 54 tested training hours?

Pass: you can document 18 months in a letter from an employer, and you have, or can complete, 54 tested training hours. Then apply through the IAAI certifications office (800-468-4224). Fail: you are not eligible yet. Spend the time on the free CFITrainer.net programs and on getting work that puts you at fire scenes.

Does the provider's page state in writing who may enroll?

Pass: the page names your situation. Fail: it does not, or it names only public agencies. Ask in writing before you pay. If you are not an active member of a public safety agency that conducts fire investigations, treat National Fire Academy R0772 as closed.

Build the work record and the knowledge together, starting with free training. Our recommended order:

1. Register at CFITrainer.net and complete the five required IAAI-FIT modules (14 hours). Then plan for the 40-hour IAAI Fundamentals of Fire Investigation course or an approved equivalent, which brings the total to 54 hours (IAAI-FIT).
2. Read NFPA 921 until you can explain how the scientific method applies to determining a fire's origin and cause.
3. Look for work that puts you at fire losses: insurance claims, a volunteer fire company, or an assistant role at an origin-and-cause firm.
4. Keep a dated log of every fire scene, your role and the supervisor who can confirm it. The IAAI-FIT application needs an employer letter and the CFI application needs signed check sheets, and records are easier to build as you go than to reconstruct. Our guide to writing investigation reports that hold up shows how to structure those notes.
5. Ask the IAAI certifications office which approved 40-hour Fundamentals course will accept you.

Three of our private investigator courses cover skills that every fire investigation ends up needing: handling evidence, writing the report and understanding court procedure. They do not count toward IAAI or NAFI credentials. Prices are as of October 2026.

• Legal Aspects of Private Investigation, $120. It covers criminal law fundamentals, categories of evidence, criminal defenses, and rules of evidence and court procedure.
• Report Writing, $80, a 4-hour course. It covers types and purposes of reports, using notes, the who, what, where, when, how and why elements, objectivity, and critiquing and revising.
• Scientific Analysis of Physical Evidence, $100, a 6-hour course. It covers forensic examination methods and includes a chain of custody lesson.

Two of our guides go deeper on points this page only touches. Interview techniques for investigators covers the witness and owner interviews that follow a fire loss, and physical or digital evidence training for private investigators helps you decide which kind of evidence training to take first.

Our courses are self-paced. Phone support runs Monday to Friday, 9:00 AM to 6:00 PM Eastern, at (832) 922-1215.
