The National Learning Infrastructure Initiative defines an electronic portfolio as
“A collection of authentic and diverse evidence, drawn from a larger archive representing what a person or organization has learned over time on which the person or organization has reflected, and designed for presentation to one or more audiences for a particular rhetorical purpose."
A good e-portfolio tells the candidates' story of growth and development over time.
Candidate e-portfolios may include MS-Word, Excel, or PowerPoint documents, images, multimedia, blog entries, hyperlinks to web pages, databases, applications, certificates, etc. It serves as a record of accomplishments, similar to a candidate’s portfolio in the real world. More and more candidates now leverage the power of computing and the Internet to develop e-portfolios. Candidates can update or tweak such portfolios to suit particular requirements with ease, and send to employers with ease.
Employers also find e-portfolios convenient, but evaluating e-portfolios is different from evaluating ordinary physical portfolios, and requires some special considerations.
