There is growing interest in coaching as a means of promoting professional development and the use of evidence-based practices in schools. This article describes the PBIS"plus" coaching model used to provide technical assistance for classroom- and school-wide behavior management to elementary schools over the course of 3 years. This Tier 2 coaching model was implemented within the context of school-wide Positive Behavioral Interventions and Supports (PBIS) and tested in a 42-school, randomized controlled trial. We summarize some of the lessons learned by coaches regarding their efforts to gain access to the administrators, teachers, and student support staff in order to effect change and improve student outcomes. We conclude with a discussion of ways to successfully collaborate with teachers to promote effective classroom- and school-wide behavior management.
