This paper suggests that the innovative synchronous and asynchronous evaluation system for the Web-Based English Instruction in terms of a set of two modes : On-line Performance- Based Testing mode and CAT(Computer-Adaptive Testing) mode. This system is suitable for the varied multimedia evaluation environment because it provides various media functions. It is estimated that this system has a high degree of efficiency, and low degree of periodical cost and time constraint. Applying the system's various functions and interfacing, we can design and implement interactive electronic authentication for language testing. On-line Performance-Based Testing mode is designed to explore the applicability of computer technology to developing more valid measurement tools for the performance testing in cyberspace. This mode can be designed to include audio/video/chatting control to conduct group oral testing. The primary aim of this mode is to provide students with interactive testing environments to supplement authentic language use. CAT mode is designed to include an adaptive tool to construct on-line adaptive testing. In this mode, a student is free to take the test at any time within a specified time frame.
