Evaluation and impact assessment

Impact contracts
Impact contracts

What are we talking about?

The impact contract is an innovative mechanism for financing social and environmental innovation.

The social and environmental innovation project leader obtains financing from private investors. The latter are reimbursed by the State if and only if the social and environmental impact of the project is demonstrated.

Impact contracts therefore bring together three types of actors with different objectives

To function effectively, impact contracts require the intervention of an evaluator.

Our method of intervention as an evaluator

An evaluator, at the heart of the Impact Contract mechanism, is necessary to

The evaluator positions himself as a trusted third party, guaranteeing the alignment of the interests of the parties to the contract.

Our 3 phases of intervention :

What is the role of the evaluator?


  • Support for project design
  • Co-construction of payment triggers and their targets
    • Requires diving into the association’s track record and looking at the counterfactual
    • Calculate SROI ex ante to confirm targets
  • Verification of the robustness of the information system and determination of audit procedures
  • Definition of informative indicators
  • Participation in the drafting of agreements.

Evaluation during the contract

  • Recovery of data from the IT and databases cleaning
  • Data audit
  • Calculation of payment triggers and drafting of the annual performance certificate
  • Participation in the reflection on how to correct deviations from the target, if necessary
  • Monitoring of informative indicators (not payment triggers)
  • Participation in steering committees

Ex-post evaluation

  • Calculation of the full ex-post SROI
  • Drafting of a final report, with recommendations on scaling up

As an evaluator of 11 impact contracts, Citizing has developed a solid line of work, led by Judith Lefebvre de Preÿ. Our approach requires flexibility in posture:
