The Pathways Clearinghouse’s ability to report on the effects of an intervention are tied to the existing evidence. Not all interventions have been studied along all the domains on which we report [earnings, employment, public benefit receipt, and education and training]. An intervention may have studies that examined effects in some outcomes but not in others. In other cases, the quality of evidence may vary across outcome domains. If we did not find any studies that rated moderate or high quality that studied the intervention’s effect on outcomes in a given outcome domain, that outcome receive an effectiveness rating of no evidence to assess support. In addition, we may not have all of the data to extract an effect size from the original study (as discussed in the previous FAQ). In those cases, we cannot report on the effects on an intervention for those domains.
