Interactive DBI Process

Intensive intervention helps students with severe and persistent learning or behavioral needs. The Center's approach to intensive intervention is data-based individualization (DBI).

What is DBI?
DBI is a research-based process for individualizing and intensifying interventions through the systematic use of assessment data, validated interventions, and research-based adaptation strategies.
