This paper proposed an extended information system continuance model (ISCM) in the context of e- Portfolio utilization among students, Based on self-determination theory (SDT). The purpose was to investigate the factors influencing students’ continuance intention towards using e-Portfolio. The 370 usable data were collected and analysed further using partial least squares. In the proposed model, satisfaction, perceived usefulness, confirmation, perceived autonomy and perceived competence were found to be significant in explaining the students’ continuance intention to use e-Portfolio. The results of this study show that applying SDT to e-Portfolio in higher education institution can be useful to predict the students’ continuance intention.
