Training teachers to listen may enable them to experience increasingly attentive and open peer relationships at work. In the present research, we examined the outcomes of a year-long listening training on school teachers' listening abilities and its downstream consequences on their relational climate, autonomy, and psychological safety. Teachers in two elementary schools engaged in a similar listening training program throughout the entire school year.

Results of growth curve modeling showed linear increases in all three outcomes, such that more listening training corresponded to a more positive relational climate. Specifically, the teachers reported increasingly higher quality listening from their group-member teachers, felt more autonomy-satisfied, psychologically safe, and relationally energetic. Furthermore, latent growth curve modeling indicated that the teachers' listening perception was positively and
