Evaluation
BIO's 2024-28 management contract aims to assess development and sustainability impact at both strategic and project levels. It is from this renewed ambition that BIO's new evaluation plan originates.

Evaluation plan 2024-2028
BIO's 2024-28 evaluation plan builds on prior evaluation experiences and aims to enhance BIO's impact management while meeting certification requirements from the Special Evaluation Office of Belgian Development Cooperation.
It represents BIO's first comprehensive evaluation framework and has been developed in consultation with the Special Evaluation Office of Belgian Development Cooperation (SEO) and the Directorate-General Development Cooperation and Humanitarian Aid (DGD), and formally approved by BIO's governance bodies.
The evaluation program serves two main, interconnected objectives: learning from experience to inform strategic decisions and ensuring accountability to stakeholders.
It is structured around four complementary evaluation instruments:
Internal assessments
- Strategic Impact Reports (yearly) - Annual portfolio-level assessments tracking BIO's impact performance against strategic targets, based on SIT assessment, monitoring of development indicators and economic modelling.
- Project Completion Reports - End-term evaluations of individual projects, combining monitoring data, internal reports, and stakeholder feedback to assess financial, business, environmental, social, and development outcomes.
External assessments
- Multi-year Strategic Impact Studies (mid-term and end-term) - Independent portfolio-level evaluations, including 12-15 case studies to assess BIO's performance against its strategic framework and theory of change.
- End-beneficiary Focus Studies (min. 2/year from 2026) - Field-based assessments examining profiles and perspectives of end-beneficiaries in selected projects, focusing particularly on African investments and inclusive businesses.
The plan's governance ensures supervision and quality of the evaluations through a Steering Committee (comprising BIO, DGD, and Special Evaluation Service representatives) for external evaluations, oversight from BIO's Board of Directors, and dedicated internal evaluation resources. Findings from external evaluations will be published with management responses.
