The present study was conducted to identify the effect of using an e-mentoring program for enhancing 3^rd year EFL students' teaching self efficacy and professional development. A quasi-experimental pre-post test control group design was employed. An e-mentoring program was developed by the researcher and used with the experimental group, whereas, the regular teaching method was used with the control group. Sixty males and females were randomly chosen and equally divided into an experimental group and a control one (thirty students each). The instruments included a needs assessment questionnaire to identify the teaching skills, and a teaching self efficacy scale and a teaching skills test. Analysis of data obtained showed that the experimental group achieved higher than the control group on both the self efficacy scale and the teaching skills test. Recommendations and suggestions for further research are presented.
