The TFI 3.0 is a significant update providing schools with a valid, reliable, and efficient way to measure their implementation of the core features of Positive Behavioral Interventions and Supports (PBIS). This latest version builds on existing PBIS fidelity measures and prioritizes mental health supports, equitable supports, and classroom implementation. In addition, the TFI 3.0 has an expanded 5-point scale with indicators, allowing teams to report on their implementation more accurately, with more guidance to support action planning.

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 manual provides school leadership teams and coaches with information and resources needed to use the TFI.
