Critical thinking skills are necessary tools for promoting postgraduates’ academic writing. This study explores postgraduates’ responses towards the role of critical thinking skills in academic writing courses. The study adopts Peter Honey Critical Thinking questionnaire which is delivered online to EFL MA students at the Department of English in the University of Tripoli in order to collect data. 20 students participate in the questionnaire which aims to find out whether EFL MA students are aware of the role of critical thinking skills in enhancing the writing of their written assignments and theses. The results reveal that EFL MA students are aware of the important role that critical thinking skills play in developing academic writing courses and in producing quality content texts.
