Hey, I found that there are four core standards to guide evaluation design clarified by the U.S. Centers for Disease Control and Prevention program. Would you please provide me with more information?

Glad to hear.

Oh, I understand it now. Many thanks!

Yes, program evaluations should follow some basic standards at all times. These standards
are related to ethical and methodological issues of importance, which mainly includes:
Utility: Make sure that the evaluation will provide relevant information on time;
Feasibility: Make sure that the evaluation activities are realistic, given the time, resources, and expertise available;
Propriety: Make sure that the rights of participating individuals are protected and that the evaluation gathers information from those most directly affected by the program;
Accuracy: Make sure that the findings are valid and reliable.
