The IAAI-ECT is a national fire-scene evidence collection credential awarded by the International Association of Arson Investigators. The practicum is a 10-component, 4-hour practical exam; candidates must score at least 70% on each component and pass all critical elements. Prerequisites within the prior 5 years are 18 months of general fire-investigation experience, 29 hours of tested CFITrainer.Net training, and documented collection of 12 forensic items. The credential is valid for 5 years; renewal requires 40 hours of tested training and education. Renewal fees are $125 (IAAI members) and $295 (non-members). The exam is grounded in NFPA 921 and ASTM E1188, E1412, E1492, and E1618.
