A chi-square test of independence confirmed that this difference was highly statistically significant, X²(1, N = 333) = 19.09, p < .001, with a small-to-medium effect size (φ = .24). Matches made through MentorPRO had roughly one-quarter the odds of closing early relative to those made manually by staff (OR = 0.25), and their closure rate was approximately one-third that of the comparison group (RR = 0.33). These  differences reflect a meaningful and replicable pattern. Zing also evaluated relationship quality, including goal and relationship strength and progress, follow-up, and commitment. MentorPRO-matched pairs scored higher on match quality than manually assigned pairs.
