Runco Ideational Behavior Scale (RIBS) is a key point in creativity research that focuses on assessing an individual's capacity for creative ideas. However, some literature shows that RIBS measurements in a gender context still do not show a clear picture. This research aims to understand how creativity based on students' gender influences counseling professionals in schools. The method utilizes the Rasch model across a sample of 627 students from various provinces in Indonesia, achieving a power measurement of 0.98. Data Collection used WhatsApp and Google Forms from May to June 2023. This study's findings revealed that (1) the inventory of students' creative ideation aligned well with the theoretical framework, and (2) there was a notable higher propensity for students' creative ideation among male students compared to female students. These results highlight the critical need to cultivate creative thought and innovation among students. Moreover, this study provides foundational data for the development of targeted interventions, such as counseling programs tailored to student needs, aimed at enhancing the creative thinking capabilities of students and guiding them toward positive outcomes.
