Tiered Fidelity Inventory (TFI) 3.0

The purpose of the Tiered Fidelity Inventory (TFI) 3.0 is to provide a valid, reliable, and efficient measure of the extent to which school personnel are applying the core features of Positive Behavioral Interventions and Supports (PBIS). The TFI is divided into three sections (Tier 1: Universal PBIS Features; Tier 2: Targeted PBIS Features; and Tier 3: Intensive PBIS Features) that can be used separately or in combination to assess the extent to which core features are in place.

The TFI 3.0 is based on the features and items of existing PBIS fidelity measures (e.g., SET, BoQ, TIC, TFI 2.1, SAS, BAT, MATT). We revised the TFI 2.1 to prioritize content related to the integration of mental health supports, equity, and classroom implementation and to better align with current guidance and training content available through the national Center on PBIS.

Our TFI 3.0 Implementation Resources page is your spot to find all of the supporting resources in one place!

The TFI 3.0 Action Plan is available as a separate fillable PDF.
