In 20 16, the state abolished the qualification examination for cost engineers and replaced it with the first-class and second-class cost engineer system. The first level is equivalent to the original registered cost engineer, and the second level is equivalent to the original cost engineer, but it is different from the cost engineer. The role, scope of use and qualification of the second-level cost engineer are far greater than those of the cost engineer. If you are engaged in cost work and need this certificate urgently, it is recommended to apply for the second-class cost engineer. As for the examination rules and requirements, they are all operated by the provincial cost associations. Please consult the cost associations for details.
