This study was developmental research. The study was development of CBT based IRT to assess students'problem-solving(PhysTePSoS-CBT). PhysTePSoS-CBT was developed based on 4D model. The PhysTePSoS-CBT was assessed by three experts to know the feasibility of PhysTePSoS-CBT. The feasibility of PhysTePSoS-CBT was assessed in the aspectsof correctness, reliability, integrity, usability, interface, and navigation. Based on the assessment from the experts, all aspects of feasibility were in excellent category with an average percentage of 98%. So, it can be concluded that PhysTePSoS-CBT was valid and has good quality. © 2020 Published under licence by IOP Publishing Ltd.
