This study aims to analyze the quality of the scientific literacy test of the impulse and linear momentum material using the Rasch model. The research method used is a quantitative approach with a sample of 30 students of class XI in one high school in Banjarmasin. The instrument used is ten scientific literacy essay questions on impulse and momentum material. The data were analyzed using the Rasch model with the Winstep program. The analysis results obtained the validity of five fits and five unfit questions. Person reliability was obtained at 0.47, which means weak, while for item reliability, 0.73 means sufficient, and the reliability between students and items is 0.51. The difficulty level of items is generally in the medium category, meaning the item is relatively easy. So the test needs to be fixed before being used for a broad trial. © 2024 Author(s).
