This investigation examined the role of students' social-emotional need satisfaction in relation to academic engagement and social-emotional skills. Among a sample of 501 secondary school students (and their parents/carers), several need satisfaction variables were examined: perceived social-emotional autonomy, perceived social competence, perceived emotional competence, perceived relatedness with students, and perceived relatedness with teachers. The hypothesised outcomes were student-reported behavioural disaffection, and parent reports of students' homework practices, expressive skill, and perspective-taking skill. Results demonstrated that perceived social competence was associated with lower behavioural disaffection. Perceived emotional competence was associated with more positive homework practices, greater expressive skill, and greater perspective-taking skill. Perceived relatedness with teachers was associated with lower behavioural disaffection and more positive homework practices. Findings have implications for supporting students' positive adjustment in school and beyond.
