Tiered Fidelity Inventory (TFI)

The Tiered Fidelity Inventory (TFI) is based on earlier PBIS fidelity surveys (SET, BoQ, TIC, SAS, BAT, MATT). The TFI gives teams a single, efficient, valid, reliable survey to guide implementation and sustained use of SWPBIS. Using the TFI, teams measure the extent to which school personnel apply the core features of SWPBIS at all three tiers – either individually or collectively.
