What is fidelity?

Developers base their programs in theory. Content, pedagogy, and implementation are not chosen at random or according to the developer's personal preference. The logic underlying each aspect of the program may be disrupted if the core components are changed or skipped.
Adaptations
Adaptations are changes to core components of an evidence-based program. While some adaptations may be helpful -- such as using inclusive language, making activities more interactive, and updating statistics -- others will compromise the integrity and effectiveness of the program.Start with the right program
All communities are dynamic and unique. Youth groups are very diverse and youth culture changes quickly. To minimize the need for adaptations, it is critically important to select a program that is a match for the community and priority population. Comprehensive Planning for Evidence-Based Programming will assure a good fit.Plan and prepare for implementation
Many of the adaptations made during implementation can be avoided through planning and communication. All parties should understand and agree to support the requirements of the selected program.Adaptation Resources
