Many teachers report using behavioral management charts in their classrooms as a means of managing student behaviors, but little is known about exactly what behaviors teachers are charting, or specifically how. Misunderstanding over how real-world teachers maintain behavioral charts may cause miscommunication between the teacher and the school psychologist. This study sought to determine how teachers collect and track behavioral data. Researchers examined behavioral charts used by teachers in a Title I elementary school that reported using Positive Behavioral Intervention Supports (PBIS). Researchers evaluated charts for ten classrooms (~150 students) and compared the type of data collected by each teacher for each child. Findings indicated that teachers either used no system, their own systems, or a computer-based system (Class Dojo) for charting behavior. An analysis of each of these systems found that Class Dojo provided significantly more data (positive and negative notations) in general, as well as more reliable data than any other system reviewed. Discussions of these findings within a PBIS framework, as well as general concerns about the computer-based system, are provided.
