This study aims to identify the acquisition of linguistic competencies by pre-service physical education teachers at the College of Education, Sultan Qaboos University, and in-service physical education teachers in Muscat and Dhofar Governorates in Oman, as well as any statistical differences between these two groups. The population of the study consisted of 30 pre-service teachers and 28 in-service teachers. The observation card instrument was used to collect data. The results showed that the acquisition level of the linguistic competencies of pre-service physical education teachers was medium. However, the acquisition level of the linguistic competencies of in-service physical education teachers was high. Furthermore, there were significant differences between the acquisition level of linguistic competencies in pre-service and in-service teachers in favor of in-service teachers. Based on these findings, we recommend developing these competencies in pre-service teachers during the teacher education program by focusing particularly on planning, implementation, and assessment.
