Global Evaluation Reports Oversight System (GEROS)
The UNICEF evaluation quality-assessment system.

The Global Evaluation Reports Oversight System (GEROS) is an organization-wide system that aims to support strengthening of the evaluation function to meet and exceed United Nations Evaluation Group (UNEG) norms and standards, UN System Wide Action Plan on gender equality (UN-SWAP) and other UNICEF commitments (including equity and human-rights based approaches).
The GEROS is managed by the Evaluation Office. The main objectives of GEROS (revised in 2016) are:
- Objective 1: Enabling environment for senior managers and executive board to make informed decisions based on a clear understanding of the quality of evaluation evidence and usefulness of evaluation reports
- Objective 2: Feedback leads to stronger evaluation capacity of UNICEF and partners
- Objective 3: UNICEF and partners are more knowledgeable about what works, where and for who.
All final evaluations are assessed by an external independent company. For additional information, please download the GEROS Guidance Handbook (2020).
Once the reports are assessed, detailed feedback on how to improve future evaluations is sent to the office that commissioned the evaluation.
Meta-evaluation reports are produced, disseminated and used to improve UNICEF decentralized evaluation function.
