The present research investigated the effectiveness of a program based on self and peer assessment on enhancing EFL learners' conversation skills. The research adopted the quasi-experimental one group pre-posttest design. Participants compromised a Conversation intermediate class (N=7) at E-planet company, Al Mokattam branch, Cairo, Egypt.  The instruments of the study were: a diagnostic test, a list of conversation skills which constitutes an analytic speaking scoring rubric, pre-posttest, and post program reflective videos. A training program based on self and peer assessment using Padlet and Google classroom applications was developed. The program lasted for 15 weeks (60 hours). Nonparametric statistics were used to measure the effectiveness of the program on EFL learners' conversation skills. Results revealed that the program was effective on enhancing the learners' conversation skills as there were statistically significant differences between the pre and post administrations of the test in favour of the posttest. Finally, a set of pedagogical implications were proposed.
