DBI Process Overview

Developed By: National Center on Intensive Intervention

This document includes an overview of the data-based individualization (DBI) process. 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. The handout provides a graphic representation of this process and an overview of the 5 steps of the DBI process. 

  • Step 1: Implement the current validated intervention program (Tier 2, secondary intervention, standard protocol intervention) with increased intensity (e.g., smaller group size, more time)
  • Step 2: Collect frequent progress monitoring data to determine whether the student is responding to the intervention
  • Step 3: If the student continues to struggle, collect diagnostic information to identify specific skill deficits or behavior concerns
  • Step 4: Use the diagnostic data along with educator expertise to modify or adapt the intervention to better to meet the student’s individual need
  • Step 5: Continue to collect progress monitoring data at regular intervals to determine responsiveness and make additional adaptations as needed
