Which action is NOT part of ensuring fidelity when implementing an intervention plan?

• A. Use inconsistent training materials
• B. Provide clear procedures
• C. Monitor implementation
• D. Collect fidelity data

Answer: (A)

Fidelity means delivering the intervention exactly as it was designed, ensuring that practices are consistent across staff and settings so that outcomes reflect the intervention itself, not variation in how it’s implemented. Providing clear procedures helps everyone follow the same steps, which supports reliable delivery. Monitoring implementation keeps track of how the plan is being carried out and allows for timely corrections if deviations occur. Collecting fidelity data gives concrete evidence about how faithfully the intervention is being implemented. Using inconsistent training materials, on the other hand, introduces variation in what is taught and practiced, undermining fidelity by making delivery unpredictable. So the action that does not fit with ensuring fidelity is using inconsistent training materials.
