This paper examines teachers' perceptions of their students' motivation and engagement and their enjoyment of and confidence in teaching. Drawing on Martin's Student Motivation and Engagement Scale, 10 facets of motivation and engagement were explored amongst a sample of 1,019 teachers. These facets comprised three adaptive cognitive dimensions of motivation (self‐efficacy, valuing of school, mastery orientation), three adaptive behavioural dimensions (planning, study management, persistence), two impeding dimensions (anxiety, failure avoidance), and two maladaptive dimensions (uncertain control, self‐handicapping). Male teachers tended to report significantly higher student motivation and engagement than female teachers (though effect sizes were small) and primary school teachers reported significantly higher student motivation and engagement than high school teachers (effect sizes were moderate). Adaptive dimensions were more strongly associated with enjoyment and confidence in teaching than impeding and maladaptive dimensions. Of the adaptive dimensions, students' mastery orientation was the strongest correlate of teachers' enjoyment of teaching and students' persistence and students' planning were the strongest correlates of teachers' confidence in teaching. These associations were more marked for male teachers and relatively independent of years spent teaching. Implications for teacher education and professional development are discussed.
