The current study examined whether the extent to which students perceived their teachers provided positive support influenced associations between teachers' emotional intelligence and social emotional learning (SEL) beliefs and multiple dimensions of students' other-oriented cognitions (i.e., perspective taking empathetic concern, and prosocial motivations and goals). Forty-three fifth-grade and sixth-grade teachers from 12 Greek elementary schools and 353 students (192 boys) were participants. The majority of students were White and of Greek nationality. Teachers' emotional intelligence was associated positively with students' empathic concern and prosocial goals. However, the association between teachers' emotional intelligence was related negatively to students' perspective taking skills, but only when students reported receiving less positive support from their teachers. Conversely, when students reported high levels of positive teacher support, teachers' comfort with SEL teaching practices was related positively to students' prosocial goals. Findings also highlighted differences in Greek teachers' emotional intelligence and comfort with and commitment to SEL teaching practices as compared to those reported in other countries. Additionally, girls rated themselves as higher in empathetic concern than did boys. Implications for teacher training and professional development that support teachers and students' SEL are discussed.
