Considering the vagueness of education objective in current civil engineering programs in China, the paper emphasizes the outcome-based engineering eductotion. The classification of engineering activities according to their complexity and corresponding education tracks defined by International Engineering Alliance are compared, and mutual relationship between graduation requirements in professional accreditation of undergraduate engineering education and engineer qualification abilities is discussed. It is suggested that the key issue of undergraduate engineering education must be the development of the ability to solve complex engineering problems, to achieve the substantial equivalence of international program accreditation. Education of the engineers' ability shall be developed step by step, thus the curriculum and course can be provided and developed rationally. It is suggested that measures should be taken to improve teachers' engineering practical ability and teaching ability according to the requirements of outcome orientation.
