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.

Why might our progress monitoring tools focus on skills that we are not teaching?

Watch and listen as Michelle Hosp, Associate Professor in the College of Education at the University of Massachusetts Amherst discusses why your progress monitoring tool may not directly focus on the skills that you are teaching. 

Lessons Learned from Implementation

NCII recently released a new document & infographic highlighting lessons learned from implementation and tips for getting started. Key lessons included:

  • Support from leadership is essential for successful implementation of DBI.
  • Solid Tier 1 and 2 foundations allowed school staff to focus efforts on DBI.
  • Starting small and moving forward one step at a time facilitates success.
  • Formalizing procedures through standardized protocols helps ensure ongoing DBI implementation.
  • Committing to trust the process led to successful DBI implementation.
