Fidelity of Implementation
In this session, Hulleman discusses the advantages of assessing fidelity of implementation, elaborates a procedure for systematically assessing fidelity, and invites participants to discuss applications to their work.
A program’s effectiveness is judged by whether it produces positive outcomes for participants, with the randomized experiment being the gold standard for determining the efficacy of an intervention. However, there are many ways to evaluate program effectiveness, including design-based and implementation methods. The intervention implemented usually differs—to a greater or lesser degree—from the program that was designed, making it unclear whether unfavorable results are due to an ineffective program model or implementation failure.
