The main purpose of this research is investigating the relationship among customer satisfaction, customer value, and relationship quality and behavior intension from the service quality point of view by using quantitative analysis approach. We also discuss which factors recognized by students are critical. The samples are collected from College Extension Education Organization for those who had ever taken such courses. The results show that the students pay much attention on teachers' specialty, provided service quality, and the functional value of course content. Through well course design, hiring professional teachers, and providing well-equipped software/hardware, the students recognition on quality and value can be improved, and the satisfaction will be increased too. The students will be willing to return for another training opportunity or recommending others for studying in this education extension organization.
