The aim of this study was to develop a valid and reliable scale to determine the curriculum approaches teachers. study group the research consisted of 181 English teachers teaching in secondary school. While expert opinions were obtained for the content validity of the scale, exploratory factor analysis (EFA) was performed for construct validity. As a result of the analysis, a scale that consists of 37 items and four-factors as "curriculum fidelity", "exam-based adaptation", "student-based adaptation" and "curriculum design" was developed. Cronbach's alpha coefficients calculated for each factor to determine the reliability of the scale vary between 0.82 and 0.90. Analyzes for the item-total score correlation of the scale and the correlation of subscales also show that the scale meets the reliability requirements. The results of the validity and reliability analysis of the scale indicate that the scale produces valid and reliable measurements. It is thought that this scale will contribute to new studies on the implementation of the curriculum.
