This paper describes the WebCAT* system. The WebCAT* is a Web-centric, multi-server system that combines the WWW, database, and Internet: all test items are stored in databases located at each CAT server; users can access these materials via the Internet through a Web browser. The testbases of these CAT servers can be shared among each other in a way unseen to end users. Each test item in the WebCAT* is associated with degree of difficulty, domain, and the testbase it belongs to. Upon test generation, a test specification with test domain and max/min degree of difficulty is given to generate the test. Each test consists of items taken automatically, at random, from all the available testbases according to the specifications. This system has three major characteristics: multi-testbase sharing, real-time test generation, and item cross-analysis. A case study of an English exam with text and audio test items is given at the end of this work as an example. The overall feasibility of network-based testing is discussed as well.
