Research confirms that the most significant factor contributing to students’ success is the quality of teaching. Accordingly, education effort for teachers is crucial to our educational objective. Professional development is one of the most effective strategies in our center for the sake of enhancing our teachers’ competence.Here, at the International Center of Teaching Persian to Non-Persian Speakers, we provide quality, accessible professional language instruction to those who are interested in learning Persian. We are committed to being carefully, insightfully and consciously innovative and also respecting where individuals are in their unique educational contexts. At the heart of our quest is a practical professional development program that emphasizes the need of research, as well as the individual and overall staff growth. This plays a vital role in our mission and by virtue of the professional development for teachers, their teaching ability can be considerably improved which not only increases students’ achievements, but also helps the teachers in their career development.It is critical to note that teachers are our most treasured resource. Therefore, we want them to stay focused and organized. They are in the very core of our program and wholeheartedly continue to collaborate on research and language teaching. The knowledge of more experienced teachers, both in research and in the abilities obtained through professional development training, openly benefits less experienced teachers who are just beginning their careers and lack confidence.
