Taking the significance of teacher motivation in professional practice and pedagogical achievements of teachers, students and their educational goals, this study aimed to investigate EFL teachers’ motivation affected by the introduction of the Fundamental Reform Document of Education in Iran. For the quantitative phase of the study, a researcher-made questionnaire developed based on the four aspects of motivation by Dornyei and Ushioda (2011) was distributed among 98 Iranian EFL teachers. Afterwards, to capture the salient factors of teachers’ motivation, a set of semi-structured interviews with 7 volunteer teachers were conducted. The results revealed that this reform has had a positive effect on teachers’ motivation yet it has not been that much comprehensive to take into account all the motivation factors except for the contextual ones.
