Tiered Fidelity Inventory (TFI)

Tiered Fidelity Inventory (TFI) is a strategy to measure the consistency of implementation for the supports offered to help students meet behavior expectations.

TFI uses schoolwide walkthroughs, staff and student interviews, and observation forms to reflect on specific practices in a building. This process is completed by an administrator or PAR liaison.
