This paper first describes the history of testing, especially that of language testing, in order to provide a background to Computer Based Testing and Computerized Adaptive Testing. Secondly, the paper introduces an implementation of CAT, whose content is English for general science and Technology,along with a description of its construction and results. The results indicate that the CAT is more efficient than TOEIC and final examinations at NIT in terms of time consumed and the number of items answered. The result has relatively high correlation coeffcients bothwith TOEIC and the final examination, which suggests that the CAT could be reliable and valid substitute for other tests. However, the termination condition and the difficulty level of items should be carefully considered in order to further increase to the validity and reliability of CAT. In addition, the quality and the quantity of the item-bank is crucial.
