The literature has identified the use of data-based, problem-solving as an essential element in the promotion of positive behavior interventions and supports (PBIS) within the classroom. The Components of a Successful Classroom (CSC) tool is an instrument which has undergone initial validation to support its use for measuring critical features of Tier 1. This study provides initial support for the validation of this classroom management observation tool as part of a problem-solving consultation framework by examining the extent to which items on the CSC tool sample the constructs of interest in classroom management. Behavioral consultants utilized the tool to evaluate Tier 1 behavior management strategies implemented by teachers in the classroom. An exploratory factor analysis (EFA) was conducted to determine factor structure of the classroom management observation tool. Findings of the EFA supported a unidimensional construct best measured with three factors (i.e., preventive supports, feedback provision and engagement, and expectations and consequences). Currently, this tool may be useful to practitioners by guiding general education consultation after identifying main concerns in teacher's implementation of Tier 1 supports and supporting implementation of PBIS practices in the classroom.
