The method used in this research is R & D which is conducted for 1 year. The research design that was designed as a 4D development model without Dissemination stages, namely Define, Design and Develop. Data were analyzed through testing validity, reliability, and confirmatory factor analysis. The results of the confirmatory factor analysis show that students' mathematical anxiety instruments need to make some changes/improvements in accordance with the suggestions and various considerations before the students' mathematical anxiety instruments are used. Therefore, it is necessary to conduct further research to obtain the desired student's mathematical anxiety instrument.
