This article reports on the findings from a study which investigated supervision in language teaching from a supervisor's and her three trainee teachers' perspectives. The data in the study were from three sources: 1) audio recordings of the supervisor's feedback sessions with each trainee teacher, 2) audio recording of an interview between the supervisor and the researcher, in which her beliefs about and her practice of supervision are investigated, 3) audio recordings of interviews with the trainee teachers, which were conducted to elicit their beliefs about and expectations from supervision. The study presents the supervisor's beliefs about supervision, her approach to supervision and her strategies to make the supervision process more beneficial to the trainees despite the time constraints and her heavy work load. Moreover, the trainee teachers' beliefs about supervision and their expectations from this process are described.
