Abstract
This study aimed at investigating the effectiveness of implementing a TEYL program to foster early primary EFL teachers' performance in storytelling of a group of 17 primary teachers from one of Cairo language schools. The quasi-experimental design called the one experimental group design was employed in the present study . A pre-post TEYL methodology test was given to the experimental group before and after the treatment. The results revealed that the experimental group post-test after the treatment outperformed the pre-test in the TEYL methodology test and in the teachers' performance observation in storytelling in favor of the post observation. This proved that the program developed participants' performance in storytelling.
