Integrity reflects the overall confidence reviewers can place in the findings of a program's evaluation based on its scientific rigor. The research integrity rating system comprises 16 criteria scored by external peer reviewers. Scores on each criterion range, on a 5 point scale, from low quality to high quality. The overall integrity score is a weighted average of the 16 criteria reflecting the merits of the science that went into the program evaluation.
5 - high confidence in results, findings fully defensible
4 - strong, fairly good confidence in results
3 - mixed, some weak, some strong characteristics
2 - weak, at best some confidence in results
1 - little or no confidence in results
