The PBIS World Book is the print version of the information on the PBIS World website, PBISWorld.com. The PBIS World website and The PBIS World Book contain links to hundreds of interventions, supports, resources, and data collection tools, all of which are organized into a tier 1 through 3 framework. It is designed to help guide users through the PBIS implementation process, starting with behavior identification and offering suggestions for interventions and data collection tools. All links with footnotes on both PBISWorld.com and in The PBIS World Book link to external websites, which are not a part of PBIS World, therefore the content on these external sites is not included in The PBIS World Book and is not a part of the PBIS World website. In general, PBISWorld.com and The PBIS World Book can be thought of as comprehensive PBIS reference tools. PBIS is widely used in schools, school districts, juvenile detention facilities, day treatments, group homes, etc. There are many resources in The PBIS World Book that could be helpful in many settings to many people. Even parents, home schoolers, clubs, Sunday schools, and many others may find useful intervention ideas. If you find something useful in The PBIS World Book, then it’s for you.
