This document discusses using data collection tools to monitor and adjust a classroom management plan. It recommends using simple observation tools once or twice a month to determine which aspects of the management plan are working, if adjustments are needed, and if revisions to the plan are required. Several example tools are provided to collect data on student behavior, teacher interactions with students, the need for intervention plans, student performance, independent work time, engagement during instruction, and student and family perceptions of the classroom.
