This study explores the impact of classroom relationships on student engagement. To determine whether improved classroom relations lead to higher levels of student engagement, surveys were distributed to 2,340 students from 117 fourth- and fifth-grade classrooms. Respondents reported the degree to which they felt support from teachers, collegiality with classmates, and engagement in classroom activities. Hierarchical linear modeling analyses were employed, the results of which indicate that supportive teacher behavior and collegial support positively affect the level of student engagement for the classrooms within this study. Implications for classroom and school relations are discussed.
