In recent years, teacher competency is regarded the critical factor for educational success. This study examine the secondary school teacher's job competencies and the difference in the order of priority of those job competencies by level of school. For this purpose, this study used literature review and Delphi method. Also, for determining the rank of job competencies, the Locus Focus Model method and Borich priority formula were used. Through the literature review and Delphi, 20 job competencies were found for the secondary school teachers. The participants confirmed the statistically significant difference between current level and future needed level for those all 20 job competencies. However, the differences were not confirmed between two groups by school level. Some implications for researchers and practitioners, as well as limitations, are presented at the end of the study.
