Counseling parents concerning students' learning processes is considered to be an increasingly important competence area of teachers. However, few educational programs exist specifically focusing on improving this essential teacher competence, particularly in early teacher education. The current study, which took place at a German university, describes the evaluation of a corresponding training program for prospective teachers as well as a process-oriented feedback intervention. We conducted a quasi-experimental study with three treatment groups (training group, training + feedback group, control group) combining pre-, post-, and follow-up test measures with time-series data. By means of multivariate repeated measures MANOVAs and time-series analyses, we were able to demonstrate that prospective teachers' counseling competence can be successfully fostered by training and individual process-oriented feedback. Our results provide several practical implications concerning the improvement of teachers' counseling competence within the context of teacher education.
