PBIS World is a website containing links to hundreds of interventions, supports, resources, and data collection tools, all of which are organized into the 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, PBIS World can be thought of as a PBIS reference tool. (PBIS World is in no way affiliated, associated, or connected with any other website, entity, or federal, state, or local government agency, department, program, policy, or initiative.)
