The increased attention to computational thinking in education is directly proportional to the assessment needed to measure the ability of computational thinking itself. This study aims to determine the item fit of instrument Computational Thinking Scales (CTS) for students majoring in Physics Education in Indonesia. The subjects of this study were 63 physics education students at four universities in Indonesia. The Rasch model is used as an analysis model to determine the fit items of the instruments used. Based on the analysis, it is known that the Outfit Mean Square (MNSQ) value is at 1.01, and the Z-standard Outfit (ZSTD) for each item has a value of -1.9 to 1.9, which indicates that the CTS instrument item is following the model used. In addition, the fit of the item is also supported by the majority of CTS instrument items having a positive Point Measure Correlation (Pt Mean Corr) value. Therefore, it can be concluded that the items on the CTS Instrument fit the research subjects, and there were no misconceptions from the subjects on the CTS instrument. [ABSTRACT FROM AUTHOR]
