Abstract: E-portfolios have been shown to be particularly effective in providing opportunities for students to tell their learning journey of their learning from beginning to end. In contrast to paper-and-pencil-based assessments, e-portfolios allow students to demonstrate the more actual knowledge, attitudes, and skills that they acquired in their learning process. This article describes the development of an e-portfolio-for value-added assessment model for pre-service teacher education.

Data were collected through questioners and checklists and were analysed both qualitatively and quantitatively. The result of this study showed that e-portfolios model was effective in asses students' learning achievement, tracking, and measuring students’ progress as well as diagnosing deficiencies that require improvement. This study offer recommendation regarding the application of the developed model of assessment in these institutions.Abstrak: E-portofolio telah terbukti sangat efektif dalam memberikan kesempatan kepada siswa untuk menceritakan perjalanan belajar mereka dari awal sampai akhir.
