This contribution explores the relation of teacher experience with features of teacher-student relationships. Cross-sectional and longitudinal data were used to investigate this relation. The cross-sectional data set consisted of data on teacher-student relationships of over 6000 teachers with 1-36 years of experience. Teacher experience was compared with the amount of teacher influence and proximity in the relationship. The longitudinal data set included data on perceptions of teacher-student relationships of 343 teachers, that were collected each year during 2-20 years of these teachers' career. Growth trajectories in these relationships were estimated for the first 20 years of the teaching career using multi-level analyses. Results showed that, on average, teachers' ideal perceptions of influence and proximity were rather stable during the career. Teachers' self-perceptions and students' perceptions of proximity in the teacher-student relationship were rather stable as well. Students' and teachers' perceptions of teacher influence on average grew in the first 6 years of the teaching career. [For Chapter 5, see EJ739721.]
