Abstract The purpose of this research was to examine the impact of using a computer assisted program on developing  pronunciation skills of primary stage EFL pupils . The  research  adopted the quasi-experimental design using thirty 5^th year primary stage pupils to be the study participants. The computer assisted program was used in teaching the experimental group in the second  term of the academic year (2022-2023). The instruments of the research  were an EFL pronunciation tests (pre-post) and an analytical scoring rubric. The data of the research  were analyzed statistically. Results showed that there were statistically significant differences between the pre-post instruments (EFL pronunciation test) in favor of the post one. The results showed that the use of the  computer assisted program  had a significant impact on developing  EFL pupils` pronunciation skills. In conclusion, the research recommended implementing the computer assisted program  inside the classroom. It was also suggested that further research should be conducted related to using computer assisted program for developing other language skills such as listening. Key words: EFL pronunciation skills and computer assisted program.
