Currently, there are various institutions performing fire investigation and identification, such as fire stations and police stations as well as institutes related to fire safety, etc. And the manpower working at the institutions reaches a large number of persons. But there is no objective index on the expertise of the persons. In this paper, we suggested the examination criteria through job analysis and the enforcement method of the exam system. And we developed suitable exam subjects and exam content specifications for qualification of fire identification and estimation that investigate a fire cause, combustion, escape circumstances and fire facilities at the scene of a fire, survey the fire damage and analysis fire cause, etc. It will increase the public trust to develop national technical qualification items of the fire identification and estimation engineer.
