The current study aimed to investigate the effectiveness of using a training program based on artificial Intelligence (AI) teaching competencies in developing primary school EFL teachers' AI awareness and English language productive skills. The study adopted the quasi-experimental design of one group and pre–post administration of the instruments of the study. The study group included twenty-five (25) EFL primary school teachers. To meet the objective of the study, a training program based on AI teaching competencies was constructed, validated and taught via project-based learning (PBL). In addition, an observation sheet of AI teaching competencies, Test of AI awareness, and a Test of English language productive skills were developed. Results of the study indicated the high effectiveness of the suggested training program in developing primary school teachers' AI teaching competencies, AI awareness, and English language productive skills. The study concluded that  a well-structured training program that integrates AI teaching competencies with PBL can significantly enhance EFL teachers' AI awareness and their English language productive skills.
