Subclaims¶

q3 i? The WWC assigned JOBSTART its highest applicable rating, 'potentially positive effects,' because one study meeting evidence standards found a statistically significant effect and no study found negative effects in the domain; the rating did not meet criteria for 'positive effects' because only one qualifying study existed. → What Works Clearinghouse 2008

q3 · i? · causal · r2

Appendix A5 documents the WWC rating decision: Criterion 1 for potentially positive effects was met by one statistically significant study, Criterion 2 was met because no study found statistically significant or substantively important negative effects, and the stronger 'positive effects' criterion of two or more studies was not met.

"It did not meet the criteria for positive effects because only one study showed a statistically significant or substantively important effect in this domain."
