Best practice is a form of program evaluation in public policy. It is the process of reviewing policy alternatives that have been effective in addressing similar issues in the past and could be applied to a current problem. Determining best practices to address a particular policy problem is a commonly used but little understood tool of analysis because the concept is vague and should therefore be examined with caution. Vagueness stems from the term “best” which is subjective. While some research and evidence must go into determining a practice the “best” it is more helpful to simply determine if a practice has worked exceptionally well and why. Instead of it being “the best”, a practice might simply be a smart practice, a good practice, or a promising practice. This allows for a mix and match approach for making recommendations that might encompass pieces of many good practices.
