Community development information service Aeris has released a set of metrics intended as a starting point for CDFIs and other community investment institutions to collect and reporting standardized impact data. The toolkit evolved based on principles discussed at a series of meetings organized by Aeris, Partners for the Common Good and other organizations in the field. It is intended to advance a set of standardized metrics that would allow CDFIs to better understand their impact performance relative to peer institutions. The metrics allow both investors and investees to measure the aggregated impact of an investment portfolio over time and in the future, supporting comparative analysis of community development investments.
