The purpose of this study was to describe the process of developing a conceptual model in the development of models of E-portfolios for Professional Competency Certification in Indonesia. Stages in the development of conceptual model begin with a review of literature that aims to analyze and evaluate the facts of the previous studies. There are six concepts that will be discussed: (a) Certification of Competence Professional, (b) Factor E-portfolio, (c) the model ICCP E-portfolio, (d) Actor Network Theory, and (e) Recommender System. In the process of Professional Competence Certification in Indonesia, the portfolio is used as a document to evaluate the competence of the workforce, which still uses paper-based portfolios. The paper based portfolio is static and limited in sharing information with others in the management process, evaluation and updating the material is also difficult. It is expected that the conceptual model will contribute to the development of e-portfolio system to be applied in the Professional Competency Certification in Indonesia.
