The purpose of this study is to determine school administrators' technology leadership self-efficacy levels and to examine whether school administrators' technology leadership self-efficacy levels differed in terms of school level, professional seniority and participation in IT in-service programs. The survey method design was employed for the study. The sample consisted of 320 school administrators from different educational institutions from a city in Turkey. The Technology Leadership Self-Efficacy Scale which was adapted for the Turkish culture by Hacifazlioglu, Karadeniz and Dalgic (2011) was used as a data gathering tool. The original form of the scale was developed based on the standards of the International Society for Technology in Education (ISTE). One Way ANOVA and independent samples t-test were used as statistical methods. The analyses showed that school administrators' technology leadership self-efficacy and sub dimensions of this self-efficacy were found to be high. The results also showed that there were significant differences in the scores of technology leadership self-efficacy and its sub dimensions according to professional seniority, participation in IT in-service programs. However, the results revealed that there was no significant difference in the technology leadership self-efficacy levels in terms of school level.
