We conducted a theory-based analysis of the underlying structure of the Tripod student perception survey instrument using the Measures of Effective Teaching (MET) database (N = 1,049 middle school math class sections; N = 25,423 students). Multilevel item factor analyses suggested that an alternative bifactor structure best fit the Tripod items, and preliminary evidence suggests that both the general responsivity and the classroom management-specific dimensions are positively associated with teacher value-added scores. In our discussion, we consider the distinct characterizing features of adolescents as raters of teaching, the implications for teacher professional learning opportunities, and key areas for future research.
