This paper proposes a design of Web based Computerized Testing System(WCTS) for distance education. The system is consistently designed to unify the functions of CATC(Computer Assisted Test Construction), CBT(Computer Based Testing) and CADA(Computer Assisted Data Analysis). The unique features of this system are addressed in the CATC and the CADA as follows : 1. The CATC assists teachers' shared use of item database, a cooperative construction of a distance test by teachers of different schools, and an interactive construction of a test. 2. The CATC has a test score distribution prediction function using past item statistics data in Item Data-Base. These functions show to the teachers the predicted score distribution during they are constructing a test. These functions are expected to assist the teachers' collaborative test construction. 3. The CADA assists an automated process of data input through test execution, marking, analysis and immediate feed-backs to the teachers, students, and the system. Especially, it is an unique feature to analyze the newly gathered data like the number of times which an student changed his/her answer to an item. Furthermore, this paper demonstrates some performances of this system for evaluating distance education between Japan and Thailand.
