Teacher-student relationship has been shown to be a powerful predictor of students' classroom and school adjustment. Beyond the characteristics of warmth, trust, and bond that define an emotional connection, a positive working relationship also includes a sense of collaboration and partnership shared between the teacher and the student. Classroom Working Alliance Inventory (CWAI)--a questionnaire that considers both teachers' and students' perceptions, and broadens previous definitions to consider variables unique to a classroom working relationship. This inventory replicates the three critical components of a successful working alliance: bond, goal, and task. Studies suggest that students who felt that they had a strong working alliance were more likely to engage in positive learning behaviours, as rated by both themselves and their teachers.
