With the increasing popularity of entrepreneurship education programs across the world, the impact assessment of such programs has gathered considerable interest of the researchers. Growing number of studies are including entrepreneurial self-efficacy (ESE) as a key predictor of future entrepreneurial behaviour and hence the scale for measuring ESE is central to majority of studies pertaining to entrepreneurship education and entrepreneurial behaviour. This study attempts to refine the existing instruments for measuring ESE by extensively reviewing the notable scales of ESE in literature and develops a comprehensive scale of ESE relevant in the Indian context. The additional components are added to the existing scales through expert discussions with the academicians as well as entrepreneurs. The scale is further verified for its reliability and validity by using appropriate statistical methods.
