No Effects Programs have strong evidence that the program did not have the intended effects or had harmful effects when trying to achieve justice-related outcomes. While programs rated No Effects may have had some positive effects, the overall rating is based on the preponderance of evidence. Class 4 - -

[note 1] A single-study icon (effective icon) is used to identify programs that have been evaluated with a single sample. A program with multiple publications listed in the evidence base may receive a single-study icon because:

  • The publications resulted from a study based on a single sample.
  • The studies that comprised the program’s evidence base did not demonstrate effects in a consistent direction.

A multiple-studies icon (effective icon) is used to depict programs that have been evaluated with more than one sample. The icon depicts programs that have more than one study in the evidence base that demonstrates effects in a consistent direction. Thus, there is greater evidence supporting the rating because with each replication it becomes less likely the results were due to something other than the program.
