This study aims to analyze an instrument that measures the creative thinking abilities of high school students regarding renewable energy. The research model used is the ADDIE model, which consists of analysis, design, development, implementation, and evaluation. CreaTSIT was tested on 27 high school students in Bandung using a targeted sampling technique. Analysis of the Rasch model shows that the overall component of creative thinking skill is reliable and valid in the "very good"category, with a Cronbach alpha score of 0.83. A personal credibility score of 0.82 is in the "good"category. An item reliability score of 0.81 is included in the "good"category. Students' creative thinking skills must be enhanced through models, methods, and media supporting them. CreaTSIT can be used to assess students' creative thinking skills. We hope this research can contribute to the Indonesian educational community, especially physics teachers and educational researchers.
