In comprehensive, integrated, three-tiered models, it is essential to have a systematic method for identifying students who need supports at Tier 2 or Tier 3. This article provides explicit information on how to use multiple sources of data to determine which students might benefit from these supports. First, the authors provide an overview of how to make an assessment schedule for all schoolwide data. Second, the authors outline how to create a blueprint for Tier 2 and Tier 3 supports in a given school, including a description of the strategy or practice; inclusionary criteria; data to monitor progress; and exit criteria. Last, the authors provide an overview of how to connect students to support and monitor their progress.
