Once school personnel have selected an evidence-based practice or program, they are ready to begin the implementation process. When a practice or program is implemented as intended by the researchers or developers, this is referred to as fidelity of implementation. Other commonly used terms include treatment integrity, procedural fidelity, intervention integrity, procedural reliability, and procedural adherence. Subsequent pages will explore actions that school personnel can take when implementing a new practice or program in greater detail.
