Abstract

Assessment is the process of assessing the learning outcomes of students to assess which of the learningu goals haveu beenu accomplished. The focusu ofu thisu studyu is of assessing the test items' validityu, reliabilityu, andu theu levelu ofu difficulty. During the 2022–2023 academic year, the data collection strategy involved using an answer sheet for the class XI final exam held in the even semester at SMAS AlAmjad Medan. There were 151 respondents overall, and the question consisted of 40 multiple-choice questions (dichotomies) with five possible categories of answers. The fit items are obtained by using the Rasch model. Version 3.7.3 of the Winsteps software was used to conduct this investigation. The following conclusions can be made based on the outcomes of the item analysis performed using the Rasch model: The questions are 95% valid and 5% invalid in terms of validity; Because 1 item (3%) come in under the most difficult category, 2 things (7.5%) go into the tough category, 33 items (82%) fall into the moderate category, and 3 items (7,5%) fall into theu easyu categoryu, theu distributionu ofu theu difficultyu levelu ofu theu itemsu fits with the rules for developing questions.
