How does CrimeSolutions.gov treat programs and practices for which there is inconclusive evidence about whether they work?

Programs with evidence that is inconclusive as to whether they achieve their intended outcomes do not receive an evidence rating on CrimeSolutions.gov. However, CrimeSolutions.gov periodically updates a static list of programs that have been reviewed by Study Reviewers, but not assigned an evidence rating due to lack of evidence. A program is placed on the inconclusive evidence list if the study (or studies) reviewed received only Class 5 study ratings indicating that there were significant limitations in the study design such that it was not possible to establish a causal relationship to the program’s justice-related outcomes.

A practice is placed on the inconclusive evidence list if the meta-analysis (or meta-analyses) reviewed received only Class 5 outcome ratings indicating there were significant limitations in the study design of the included evaluations that it was not possible to establish a causal relationship to the practice's justice-related outcomes.
