This study examined the links between Israeli teachers' perceptions of children with developmental delay (DD) in special education kindergartens and changes in children's development. Participants were 47 teachers and children diagnosed with DD. At Time 1, teachers' perceptions were assessed via the valence of their narrative about the child and the extent to which the narrative was multifaceted (i.e. addressing more developmental domains). Kindergarten therapists reported twice, at Time 1 and at Time 2 (12 months later), on children's adaptive behavior in terms of communication, socialization, motor, and daily living skills and on children's peer acceptance. Positive valence of teachers' narratives was associated with more gains in children's adaptive behavior from Time 1 to Time 2. Multifaceted narratives were associated with children's increased peer acceptance from Time 1 to Time 2. Results highlight the importance of supporting teachers' construction of positive and multifaceted perceptions of children through training and supervision.
