Specifically, the research objectives are (1) Describe the steps for preparing a HOTSbased mathematics learning outcome test instrument using the Rasch Model, (2) Describe the results of the analysis of test items that meet the characteristics of the items that are feasible at the limited trial stage, (3) Describe the results of the analysis test items that meet the characteristics of the proper items based on the Rasch Model, (4) Describe the characteristics of a good test instrument according to the Rasch Model. This type of research is a 4-D model development research with the steps (1) Define, namely front end analysis, student analysis, concept analysis, task analysis and goal determination, (2) Design (design), namely compiling a grid, determine the form and number of items, formulate questions, determine the length of the test, (3) Develop (development), namely review tests, test trials, analyze test results, improve tests, assemble tests, (4) Disseminate (spread), namely carry out. The research sample was students of class VIII SMPN 3, SMPN 10, and SMPN 20 Pontianak, totaling 188 students. The conclusions are (1) The test development step consists of four stages, namely: the defining stage namely; front end analysis, learner analysis, concept analysis, learning objectives analysis (2) The HOTS-based junior high school mathematics learning outcomes test has the suitability validity of the panelists as many as 30 items and has a very high level of panelist reliability suitability. (3) A total of 25 items have met all the characteristics of the items. (4) Characteristics of the items on the test instrument are feasible according to the Rasch model in this study.
