This study explored the content and nature of teachers' knowledge and perceptions of their students. The knowledge and perceptions of seven Dutch secondary school teachers regarding the same 33 students in one second-year school class were studied. Each teacher was invited to tell (in 60 s per student) how he/she perceived and what he/she knew about, each individual student. Interview data were analysed using both qualitative and quantitative methods. Results showed within- and between-teacher differences in the content, amount and evaluative nature of their knowledge and perceptions. In addition, there were within- and between-student differences in how their teachers knew and perceived them. The results suggest that teachers' knowledge and perceptions of their students varies per teacher-student combination and substantiate an interpersonal nature of teachers' knowledge and perceptions. To understand the function of teachers' knowledge and perceptions of students for teaching, future research should focus on how different knowledge and perceptions lead to differential educational trajectories for individual or specific groups of students.
