Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? The study reported differences favoring the comparison group on ethnic identity, civic attitudes and participation, and two measures of moral reasoning, with all WWC-calculated effects neither statistically significant nor substantively important. → What Works Clearinghouse 2006

WWC table shows ethnic identity ES -0.19 (improvement index -7), moral reasoning P score ES -0.10 (-4), D score ES -0.07 (-3), all not significant; civic attitudes and participation showed ES +0.16 favoring the program in the table despite the text grouping it with comparison-favoring outcomes.
