The MPG’s Program Rating Tool, which was previously used by the expert peer review panel to determine a program’s rating of effectiveness, has recently undergone some revisions. The rating instrument is now in line with the Program Evidence Rating Instrument used by the Office of Justice Programs’ new Web site, www.CrimeSolutions.gov.
The new instrument continues to rate the same four dimensions of program effectiveness: the conceptual framework, the evaluation design, outcome evidence, and program fidelity. However, the individual elements in each dimension have been modified. In addition, the scoring procedures have changed such that expert reviewers will no longer assess the entirety of a program’s evidence base to determine a final rating of effectiveness.
Rather, reviewers score the most rigorous evaluation research available that will make up the program’s evidence base. No more than three studies will be included and scored as part of the evidence base. A program’s final rating will be determined by the overall strength of the studies included in the evidence base.
Many of the juvenile justice–related programs included in the MPG will also appear in the CrimeSolutions.gov database, but the final ratings used by the two sites differ. (The MPG currently rates programs as exemplary, effective, or promising. CrimeSolutions.gov rates programs as effective, promising, or no effects.)
Programs that were accepted for inclusion in the MPG before January 2011 will undergo a re-review to ensure conformity with the criteria and standards set by the new instrument. The following outlines how MPG’s existing database will be reassessed:
