Students who demonstrate the most challenging behaviors are at risk of school failure and are often placed in alternative schools, in which a primary goal is remediating behavioral and academic concerns to facilitate students' return to their community school. Consistently implemented evidence-based classroom management is necessary toward this goal; yet, many teachers report not having the necessary knowledge or skills to effectively manage behavior in their classroom. Implementation Planning (IP) is a proactive and efficient implementation support that has evidence of being effective when delivered by a consultant during behavioral consultation. The primary aim of this multiple baseline design study was to extend the findings on consultant-mediated IP by evaluating the effect of a self-guided, computer-based version of IP on teacher treatment integrity of classroom management plans. Unlike previous studies of consultant-mediated IP, results from this study indicated a minimal effect across dimensions of teachers' implementation, and thus also on student disruptions.
