Four teaching assistants and two experienced teachers were randomly chosen for this study. Data was collected through four phases. Phase one: a closed-ended questionnaire was used to find out the teaching assistants‟ current perceptions of teaching skills. Phase two: the participants were engaged in observing experienced teachers. During the third phase, the participants were involved in teaching to be observed by experienced teachers. In the last phase, teaching assistants‟ perceptions were re-examined through the same close-ended questionnaire and through the observation of experienced teachers. This project is guided by the following research questions: how competent are EFL Libyan Teaching Assistants in undergoing teaching? And how effective is the implementation of Peer Observation in developing those Teaching Assistants?. The findings of this study indicate that classroom observation is a useful technique for developing English language teaching skills. arabic 7 English 47
