The objective of this research is to design and develop the online physics test system which is conducted at SMA CT Foundation Medan. This research is a part of Research and Development (R&D) which accommodates Van de Akker method in the development stages. The subject of this research is class XII consisting of 48 students who interest in natural sciences majors. This research consists of four stages namely: preliminary research; prototyping; summative evaluation and reflection stages. This research instrument consists of validation instruments and tests. The results of this research are: i) the online test system product is feasible to use because it fills the standard of system eligibility indicators including content, interface, navigation, configuration, and security with the percentage of 86,60% which is in a decent category; ii) the product also satisfy the media feasibility standard including correctness, reliability, integrity, and usability with the percentage 81.30% which is in a good category; iii) the results of student response testing including indicators of correctness, reliability, integrity, usability, and usefulness give percentage 86,90% which is a very good category. Thus, this online test system can be used to as a medium to measure students' abilities in physics subjects. © Published under licence by IOP Publishing Ltd.
