This study aims to develop and to test the feasibility of Computer Based Testing (CBT) system for General Physics courses that can be used as a media to measure the ability of student. This research involves a part of Research and Development (R & D) for developing CBT product and also descriptive research for qualitative and quantitative data processing. The collected data as a result of assessment are validated by a team who are experts in analyzing qualitatively and quantitatively. The procedure of implementation consists of three stages, namely preparation, implementation and final stages. In the preparation stage, the CBT system is accommodated in preparing application and all items. In the implementation stage, the feasibility test is conducted through an assessment supported by IT Expert Team. In the final stage, the assessment results of the IT Expert Team are used as a basis for evaluating the CBT system. As result, the Computer Based Testing (CBT) system has fulfilled the criteria of question eligibility through content validity testing with aspects of matter, construction and language. The average value is 75.6 that satisfy valid criteria with minor revisions as well as satisfy eligibility system which includes Content, Interface, Navigation and Security indicators with the percentage is 86.6% involving the category of the level of eligibility which is in very good level. Thus, it can be used as a medium for student exams in the General Physics course. © Published under licence by IOP Publishing Ltd.
