In extant research, the concept of student engagement refers to individual behavioural patterns and traits. Recent research indicates that engagement not only should be related to the individual but also should be anchored in the social context. This ethnographic field study of students and teachers in a Danish vocational education and training school responds to the need for more knowledge on this theme by exploring the social dynamics of engagement perceptions. Results show that teachers and students held diverging perceptions of student engagement that rested on educational goals as well as goals related to the perceived future work settings. The misrecognition of the students' perception of engagement had direct negative consequences for student performance and school attachment. The implications of the findings are discussed in detail.
