Feedback is necessary for English language Teaching (ELT) students due to their difficulties while writing theses. Presently, limited research has been conducted on students' preferences and perspectives regarding feedback received on the thesis. Many undergraduates extend or discontinue their four-year studies due to thesis advisers' unprecedented expectations, which discourage timely responses to feedback. Therefore, this research examined students' opinions regarding the types of feedback preferred during thesis preparation. This research used a case design and recruited participants from groups of students completing their theses under the supervision of seven doctoral-level advisers. Key findings were that thesis advisers' feedback on students' research projects was insufficiently detailed as opposed to the significant amount anticipated. In this case, the advisers may have been unaware of the amount of significant feedback required on initial and subsequent drafts. Besides, advisors provided more feedback on linguistic than content issues, as opposed to students of undergraduate level due to limited research capacity. The results showed that students are expected to have written and oral feedback in the one-to-one consultation.
