Discover fit-for-purpose impact measurement & management resources

What is the Impact Toolkit?

The Impact Toolkit is an IRIS+ resource managed by the Global Impact Investing Network (GIIN). It is a digital database designed to consolidate otherwise fragmented impact measurement and management (IMM) resources and direct users to those that are most relevant to their IMM needs. Resources in the Impact Toolkit can also be found through the Strategic Goal pages in IRIS+.

How do I submit my resource?

To contribute a resource for inclusion in the Impact Toolkit, please visit the Impact Toolkit Contribution Portal. From there, download and complete the Excel template, and then email the attached file to We kindly ask that contributions only be made for the resources that you have directly had a hand in creating/managing.

How can I find more resources that may be relevant?

An easy way to surface additional resources is by selecting the Cross-Category option in Explore or Customize.  

What is the difference between Systems, Methods, Indicators, and Data?

These the four generally distinct types of resources in the Impact Toolkit. Systems have been classified as principles, standards, frameworks, conventions or models –  these resources serve as structures through which different impact measurement and management activities can be approached. Methods have been classified as guidelines or measurement techniques – these are resources that tell you directionally how to do something. Lastly, Indicators are metrics sets or other cataloged indices, and Data includes research, case studies, and databases of evidence. 

What is the criteria for inclusion of a resource? 

Resources in the Impact Toolkit need to be relevant to IMM and useful for impact investors. If a resource isn’t appropriate for the Impact Toolkit, or should not be included for another reason, an explanation will be provided. 

Why are some of the resources included here not free?

Resources that are freely available, as well as resources that require some sort of financial transaction to access are in the Impact Toolkit. The purpose of the Impact Toolkit is to provide a means to discover what resources may be relevant to a user’s needs. Aafter the point of discovery, a more thorough examination will be required to determine if a resource will provide added value.
