This document discusses evaluating the impacts of small grants provided to organizations. It presents the intervention logic of how the grants are intended to improve organizational capacities and member outcomes. A mixed-methods research design is proposed to assess these impacts, including comparing key indicators before and after the grants for treatment and comparison groups. Challenges in attribution are addressed, such as other factors influencing outcomes. Quantitative and qualitative tools are presented to measure organizational social capital and capacities. Comparative case-based analysis methods like qualitative comparative analysis are discussed to better understand configurations associated with success.
