The method by which aspects, strengths, and weaknesses of programs and practices are consistently and objectively rated for evidence. For programs, the scoring instrument is a compilation of the dimensions and elements of a research study that are reviewed and assigned a numerical score by the CrimeSolutions.gov Study Reviewers in order to assess the evidence of a program’s effectiveness. The instrument provides a standard method to assess the quality of each program’s evidence base, while also reflecting Study Reviewers’ judgment and expertise. A similar method of scoring the aspects of meta-analyses is used for practices. See Program Review and Rating from Start to Finish or Scoring Instrument for more information.
