Abstract
This study aims to design a scientific reasoning ability test on static fluid material for prospective physics teachers and test the reliability of the test with the analysis of the polytomous Rasch model. The method used is a descriptive explanation. The test is in the form of a description of five questions measuring proportional reasoning ability, probability, correlation, and deductive hypothesis. The test was given to 28 (M=3 dan F=25) prospective teachers in one of the state universities in Bandung. The results obtained are item reliability 0.93, person reliability 0.84, and Cronbach Alpha reliability 0.85 with excellent categories. The result of the raw variance validity test was able to test the diversity of students' scientific reasoning abilities. The difficulty of the questions in the medium category, the accuracy, and the distinguishing power is in the excellent category
