Self-efficacy has an important role in career decision making. To get an accurate student’s profile of career decision making self-efficacy, required a good instrument. Unfortunately, there was only one instument of career decision-making self-efficacy and there was no improvement or current development. That instrument developed using classical test theory, an approach that had been criticized, especially about raw score and data interval. This study focused on career decision making self-efficacy scale’s development using Rasch model, an approach that had more advantages compared with classical test theory. The subjects were 144 students of grade 11 in Yogyakarta. Based on the analysis results using Winsteps program, there were 20 fit items (from 36 items) with Alpha reliability coefficient was 0,91. Overall, it can be concluded that the career decision making self-efficacy scale had been proven as a good instrument because had good psychometric properties. So in future, this instrument can be used for assessment and research.
