OSM Kenya participated in the testing and validation of the APHRC model, aimed at assessing its accuracy, reliability, and applicability in addressing the intended research objectives. The process involved evaluating the model’s assumptions, testing its predictive performance on real-world data, and ensuring that its outputs align with observed patterns. Validation was conducted through comparison with benchmark datasets, stakeholder feedback, and scenario analysis to determine the model’s robustness. The findings confirmed that the model meets the required standards for credibility and usability, providing a strong foundation for evidence-based decision-making and future applications.
