IAAI-CFI study plan

Map the full NFPA 1033 scope against the IAAI-CFI task domains and list every job performance requirement you must be able to demonstrate

Define the CFI role boundaries, the origin-and-cause investigator's ethical duties, and the difference between the public and private investigator's authority

Assemble the core reference set (NFPA 921 current edition, NFPA 1033, applicable codes) and note which chapters feed each job performance requirement

Build a personal glossary of at least 40 fire-investigation terms with definitions you can state from memory

Explain the scientific method as applied to fire investigation and identify where each step appears in a report

Distinguish hypothesis formation from hypothesis testing and describe how to falsify a fire-cause hypothesis

Identify the systematic approach stages: data collection, analysis, hypothesis development, testing, and conclusion

Compare the burden of proof and evidentiary standards that apply to fire-cause determinations

Describe the fire dynamics fundamentals needed to interpret burn patterns: ignition, flame spread, heat release, ventilation, and compartment fire stages

Explain how ventilation, fuel load, and compartment geometry alter burn patterns and confuse origin interpretation

Differentiate char patterns, heat lines, and smoke deposition from indicators of ignitable liquid involvement

Identify the limits of pattern interpretation and when physical evidence testing is required

Execute the origin-determination workflow: exterior survey, interior survey, and systematic elimination of all possible origins

Apply the concept of the area of origin versus the point of origin and document how each is narrowed

Identify the role of fire patterns, witness data, and fire modeling in validating an origin hypothesis

Recognize when an origin cannot be determined and how to document that conclusion defensibly

Explain cause classification categories and the criteria separating accidental, natural, incendiary, and undetermined causes

Describe how each cause classification must be supported by evidence rather than by absence of an accidental explanation

Identify the elements investigators must evaluate for incendiary cause, including the presence of an ignition source and a competent ignition sequence

List the documentation required when a cause is classified as undetermined

Describe scene safety responsibilities, including structural, electrical, chemical, and environmental hazards, and the authority to stop work

Explain evidence identification, documentation, packaging, chain of custody, and spoliation-avoidance practices

Identify the legal considerations for scene entry, consent, warrants, and the private investigator's limits

Outline the components of a complete fire investigation report and the criteria for a defensible conclusion

Explain the role of laboratory analysis, fire testing, and expert consultation in supporting or refuting a cause hypothesis

Describe how to evaluate and rely on fire modeling, reconstruction, and simulation outputs without overstating certainty

Identify common cognitive biases and how to counter them during cause determination

Prepare to defend a cause conclusion under cross-examination, distinguishing fact, inference, and opinion

Integrate all job performance requirements into a single end-to-end case file from scene to conclusion

Identify and close remaining weak areas from the week 1 competency map

Rehearse explaining the scientific method, origin determination, and cause classification aloud within time limits

Verify currency of referenced standards and codes used in your notes
