Introduction: Appropriate professional conduct of clinical teacher is vital in their medicine practice. In UKM medical centre Malaysia, personal and professional development (PPD) of future medical professionals is greatly emphasized. The objective of this study was to determine the medical students' perception about the professional conduct of their clinical teachers at UKM medical centre. Methods: It was an online questionnaire survey conducted among the clinical students enquiring about the professional conduct of their clinical teachers. There were five statements and one open ended question which described students' preference about PPD teaching- learning method, expectation on PPD session, need of teachers training and experience about the excellent and inappropriate professional conduct of clinical teachers. The open ended question described what students had observed regarding the 'doctor-patient relationship' medical ethics and 'student-teacher relationship. A total of 77 questionnaires were returned after complete evaluation. The data were compiled and analysed using SPSS version 20 and the answers to the open ended questions were transcribed. Result: Role modelling was the preferred teaching-learning method for PPD as stated by 38% respondents; subsequent preferred methods were small group (30%), role play (24%), large group (7%) and reflective writing (1%). Majority (67.5%) respondents indicated that professional conduct of their clinical teachers was frequent enough as they had expected while 29.9% claimed that professional conduct was infrequently emphasized. Excellent professional conduct of clinical teachers was witnessed by 73% respondents while 27% indicated that they had never seen excellent conduct. When asked about inappropriate professional behaviours by clinical teachers, 53% indicated to have witnessed. Qualitative data also revealed both positive and negative experiences as reflected in open comments. According to 70% respondents clinical teachers required training to apply PPD in their daily practices. Conclusion: Professional conduct of clinical teachers as perceived by the students was excellent and frequents enough with experience of inappropriate behaviour too. Role modeling was the preferred teaching method while attention needed on reflective assignment. Educators must emphasize on role modelling in their daily practices and curriculum planners should give due importance on training needs of clinical teachers to apply PPD in their daily practices.
