The National Center on Intensive Intervention (NCII) developed this self-paced module to increase users' knowledge of intensive intervention and data-based individualization (DBI). The module defines intensive intervention and DBI, describes how intensive intervention fits within a tiered system such as MTSS, RTI, or PBIS, demonstrates how intensive intervention can provide a systematic process to deliver specialized instruction for students with disabilities, and includes two case examples to allow viewers to apply new knowledge.
