This step-by-step guide shows teachers and administrators how to implement a proactive schoolwide discipline plan in individual schools and throughout school districts. Originally developed from a five-year federally-funded project (Project PREPARE) at the University of Oregon, this information was initially field-tested in over 60 schools across the country. Steps for Developing a Proactive Schoolwide Discipline Plan explicitly guides education practitioners in understanding the importance of effective discipline plans, discussing why collaboration is critical in any discipline plan's success, and providing a practical six-step procedure for effective preparation and implementation of schoolwide behavior discipline plans.
