Universities in Hong Kong have employed many part-time lecturers (PTL) for economical and operational reasons. However, the contributions of PTLs have not been fully recognized by the institutions. One of the reasons for this “unfair” situation is that PTLs are often gauged by traditional evaluation systems with criteria that cannot effectively measure the professional behaviors of PTLs. It is suggested that a better way to judge the performance of PTL is to look through the eyes of the students - the most important stakeholder. This study investigates the key behaviors and attributes that best reflect the Hong Kong students’ perception of an effective PTL. The result of a pilot study suggests that the PTLs’ behaviors inside the classrooms are perceived by the students to be more important than the PTLs’ academic qualification or social status. The finding of this study will be useful to the administrators of the universities when they set up their policies for recruiting and training PTLs.
