With the development of science and technology, a large number of advanced technologies are applied to medical equipment, which play an increasingly important role in clinical engineering. Therefore, new requirements are put forward for clinical engineering and clinical engineers in hospitals. This study comprehensively analyzed the training objectives and certification assessment of clinical engineering in many countries around the world. Combined with the current situation in China, it is of reference significance for the discipline construction and certification assessment of clinical engineering at the present stage in China, so as to promote the development of clinical engineering in China and speed up the development and certification of international clinical engineering.
