This study was conducted to determine self-efficacy levels of English Language teachers in terms of creative drama usage. Thereby the self-efficacy of the language teachers in terms of drama usage was analyzed according to such variables as type of the school they are working, gender, length of service and any course or lesson taken about creative drama. The participants were 156 teachers working within the borders of Siirt Province, a Southeastern town in Turkey in 2015-2016 educational years and taking part in the study voluntarily. A Scale created by Can & Canturk-Gunhan [11] called "Self Efficacy Scale in terms of Creative Drama Usage" was used to collect data. The Cronbach Alpha Reliability level was found to be 0,96. The data collected in the study was analyzed according to independent samples t-Test, one way analysis of variance (ANOVA test), and Mann-Whitney U test in SPSS program. The results of the study show that there did not appear a meaningful difference of self-efficacy levels in terms of creative drama usage according to gender, school type or any course or lesson taken for drama usage but there was a meaningful difference as for the length of teaching years.
