An electronic portfolio is best constructed keeping in mind the concepts of "COLLECT, SELECT, REFLECT, and PROJECT" (Burke, Fogarty and Belgrade, 1994).
There are three main types of portfolios: showcase portfolios, process portfolios and accountability portfolios. An educator may construct an eportfolio for any one of those reasons, and in fact, it could be all three.
Showcase portfolios are created by a learner to showcase their best qualities to an audience, whether marketing services as a professional (such as an artist or web designer) or applying for a job.
Process portfolios are a purposeful collection of student work that documents student growth from novice to master.
Accountability portfolios are a group or collection of Accountability Items, including any related data and information artifacts, that all combine to form a specific context of relevance.
