The UK pattern and the USA pattern have been acknowledged internationally as the typical certified engineer patterns.  A few developed countries have already established the mutual acceptance agreement on engineer qualification on the basis of the engineer system.  The consistency of engineers'educational background,  working experience,  qualification examination and further education are regarded as the basis of these international engineer agreements.  The Personnel Ministry of China has carried out various engineer management systems in different stages,  which are beneficial to the economic growth of the country, and the Personnel Ministry has also done years of fruitful explorations and obtained rich experience in the trial implementation of qualification logon system.  The authors think that the main principle of China's new engineer specialty classification is to accord with its national conditions and be in line with the international conventions.  China's engineer specialty classification should be fused with the international engineer specialty classification,  consistent with the basic principle of the international engineer mutual identification and its own present engineer specialty classification situation.  According to whether the specialty relates to the social and public benefit and the citizen security of life and property,  the new engineer specialty can be classified into two categories: registered engineers and non-registered engineers.  Drawing on the experience of UK and USA engineer specialty classifications, synthesizing China's present situation,  and summarizing a series of the current occupation classifications and the code table of discipline classification,  the Chinese engineers can be classified into thirty-five categories according to specialties. Certain categories can be further divided into several sub-categories. Suggestions about constructing EMC are provided
