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.

New Tools to Measure Fidelity

These tools were designed to help DBI planning teams and interventionists review and improve student-level DBI implementation and monitor fidelity. The Student-Level DBI Implementation Checklists allow intensive intervention teams to monitor implementation of the DBI process during initial planning and ongoing review (progress monitoring) meetings. The Daily and Weekly Intervention Review Logs collect information on day-to-day student plan implementation. Interventionists or planning teams can use the Intensive Intervention Implementation Review Log to review, document, and improve implementation of DBI process for the group of students they serve.
