What Is Fidelity?
Fidelity of implementation is defined as the accurate and consistent application of an agreed upon procedure. There are several interchangeable terms related to fidelity of implementation that include: “procedural fidelity”, “procedural integrity”, “treatment integrity”, and “treatment fidelity”. The terms all refer to the same idea: that something has been accomplished according to a predetermined plan. In order for an outcome to be attributed to a plan, it is necessary to know if the plan was implemented at all, and then implemented as planned on a consistent basis. When plans, methods, or programs are implemented as planned, outcomes and data are established as being reliable and valid. In order for schools to establish accountability for student outcomes, it is critical to evaluate and document fidelity of implementation.
