We have developed some education support systems using Web，and made some trials of the systems in our college. This paper reports one of the above systems，the Web-based examination system. There are many advantages in learning and examination using PC，compared to the conventional methods via books and paper texts. However，some problems such as authoring load and diversification of the test form and test security were pointed out. Here，by solving these problems，we present Web-based examination system that has advantages for both teachers and students .I n this system，security environment of the client PC was drastically improved further than the Web browser by the adoption of the secure exclusive client operation screen.

In the recent developments of the high-speed network technology，it is expected that high-speed communication infrastructure will improve environments of research and education in university. We have tried to develop Web-based systems which support educations for these several years. These systems are classified into two categories: one is“the lecture supporting systems" and the other is“the learning and examination systems". In a series of papers，w e are going to report these systems. The present paper gives an outline of the former，which consists of three parts: ① VLSI design education system， ② the system of telemetering experiments，and ③ the system of virtual experiments in physics. Some of them have already used for some classes in Hiroshima Institute of Technology.
