In this study we aim to conduct a complete evaluation of the e-portfolio application in the distance teaching practice course that is part of the Distance English Language Teacher (DELT) program at Anadolu University from the perspective of three groups: university supervisors, preservice teachers, and cooperating teachers. Using a survey on the needs of preservice teachers and how well these were met according to the three groups' perspectives, we gathered qualitative and quantitative data on the feasibility of the e-portfolio application. Our analysis of the findings revealed that all three groups agreed about the needs of preservice teachers. And despite some minor variance in the perspectives of each group, we determined that e-portfolio applications can meet the majority of the planning, teaching, and reflection needs in the teaching process. We offer suggestions to improve e-portfolio applications so they will better meet preservice teachers' needs.
