This paper aims to empirically test the impact of entrepreneurial competencies on the performances of SMEs in Bangladesh. The data are obtained from 115 entrepreneurs by a structured questionnaire. The partial least square structural equation modeling (PLS-SEM) method is applied to find the causal relationship between exogenous and endogenous variables. The results reveal that the organizing and leading, learning, relationship, and commitment competencies of entrepreneurs have a meaningful impact on SME performance. On the contrary, strategic and opportunity competencies have no effect on the performance of SMEs. The contribution of this study is to find out the relevant entrepreneurial competencies and to empirically test their impacts on the performance of SMEs in a developing country setting. This study gives insights into the policymakers regarding the entrepreneurship training and development program. Finally, the competency measurement of this study provides a unique scope for designing such training and development programs for entrepreneurs.
