In general, a test was developed based on classical test theory which had many weaknesses, therefore the test in this research was developed based on modern test theory (Item Response Theory). This study aimed to develop a Creative Thinking Skills test on physics lessons for Class X High School (PhysCreTHOTS) that eligible to be used based on modern test theory. This research was a development research using 4D model which involving 300 students of Class X High School in Gunung Kidul District of DIY. The scoring of test items using four categories of politomus scales and Partial Credit Model (PCM) techniques. The characteristics of the test consist of item match, reliability, difficulty level of item, information function and Standard Error of Measurement (SEM). The results showed that the instrument’s reliability was 0.72. The entire test instrument is considered fit with PCM, with an INFIT MNSQ range of 0.93 to 1.10. The difficulty index of 63 items ranges from-1.06 to 1.04. Based on the information function and SEM it is known that the test instrument corresponds to the learner with a score of-1.8 to 3.0. The entire test is considered feasible to be used to measure Creative Thinking Skills in Physics lessons for high school X grade students. © 2018, Universitas Negeri Yogyakarta (Yogyakarta State University).
