| Abstract 
 Student Evaluation  of Teachers (SET) is increasingly regarded as an important component of  assessing the performance of academic and teaching staff at the university  level. On the other hand, academic and teaching staff members are encouraged to  engage in self-reflections, reflecting upon the ways they teach. This paper  adopts a critical approach in examining the advantages and disadvantages of  using SET to assess the performance of academic and teaching staff, and of  conducting self-reflections among teachers. It is argued that while SET can be  used a reference for academic and teaching staff to improve their teaching  skills, pedagogy and course content, self-reflections of academic and teaching  staff members can be a useful strategy of perfecting teaching as well.
 The advantages of  using SET embrace (1) the feedbacks from students to teachers, (2) the need for  teachers to respond to those feedbacks, and (3) the closing of the feedback  loop if students’ views are taken into account by the teachers to improve not  only the content of the courses but also pedagogy and teaching methods.  However, the disadvantages of using SET include the following: (1) the tendency  of relying SET scores excessively to determine the teaching performance of  academic and teaching staff, whose teaching can be evaluated also by other  means, including the application and acquisition of teaching development  grants; (2) the tendency of a minority of students to retaliate against  teachers by using negative comments and scores; and (3) the tendency of a  minority of teachers to boost SET scores through a variety of methods prior or  during the conduct of SET surveys.
 
 In light of the  advantages and disadvantages of SET, teaching self-reflections can be one of  the most useful means through which teaching skills, course content and  pedagogy can be perfected. Self-reflections of teaching can be conducted by  encouraging academic and teaching staff members to write reflectively on each  of the courses they teach at the end of the semester, thus constituting a  useful individual teaching portfolio. Self-reflections of teaching can also be  accompanied by peer observations of classroom teaching so that peer  observations with constructive comments and suggestions from other colleagues  can stimulate the process of self-reflections on the part of the teachers  concerned. Indeed, such self-reflections can also be deposited in a database  not for sharing, mainly because of privacy reasons, but for better data  management for individual teachers.
 
 Overall, given that  SET scores provide one of the instruments of universities to evaluate teaching  performance of academic and teaching staff, self-reflections of staff concerned  and their combination with constructive peer observations can be considered and  conducted so that a supportive environment for the improvement and perfection  of teaching can be fostered and sustained.
