Self-efficacy is described as an individual’s beliefs about their abilities to complete an action. It is a part of the social cognitive theory in the chemistry learning process. self-efficacy consists of six aspects, namely the choice of activities, effort, perseverance, learning, achievement and strategy orientation. The objective of this study was to develop an instrument of chemistry student virtual Laboratory self-efficacy (CSVL-SE) in a virtual laboratory within the chemical equilibrium topic. This research used research and development (R&D) method. The data was obtained through a self-efficacy questionnaire. The expert confirmed the content validity with 26 items that had been administered to 60 students in senior high school. Rasch Model used to analyse the data that met the unidimensionality, item fit, difficulty or ability estimation, reliability, and information function. The findings showed that 26 items match into the Rasch Model with reliability person and reliability item of 0.84 and 0.97. So that, this instrument is appropriate to collect the data.
