A Promising program may result in the intended outcomes. A Promising practice outcome indicates, on average, there is some evidence that implementing a program encompassed by the practice will achieve the intended outcome.
A No Effects program is unlikely to result in the intended outcomes and may result in negative outcomes. A No Effects practice outcome indicates, on average, there is strong evidence that implementing a program encompassed by the practice will not achieve the intended outcome or may result in a negative outcome.
A Program is a specific set of activities carried out according to guidelines to achieve a defined purpose. Program profiles on CrimeSolutions tell us whether a specific program was found to achieve its goals when it was carefully evaluated.
A Practice is a general category of programs, strategies, or procedures that share similar characteristics with regard to the issues they address and how they address them. Practice profiles tell us about the average results from multiple evaluations.
