Portfolio is a document describing skills, experience, interest or knowledge of a person. Currently, the conventional portfolio paper-based is no longer able to keep pace with times. Therefore, some researchers suggest e-portfolios overcome this weakness. Previous studies have attempted to create a model of ideal e-portfolios. This includes Shopping Trolley Model, Toast Rack Model, Spinal Column Model, Mixed Cake Model. However, most of the previous studies on e-portfolio are in the education domain. It is rare to find research on e-portfolio for managing certification of professional competence. This study focuses on literature review and previous works on definitions, model, type, and system of e-portfolios. The results of this research are expected to give a contribution on scientific, conceptual, as well as theoretical development in Information Systems. The results on cab are used in further research to define suitable e-portfolio in Indonesia, model, critical success factors and e-portfolio system for ICT professional certification in this country.
