School-feeding is an important intervention to attract children to school and augment their learning. The benefits of school-feeding cover several domains. Key to the overall assessment of these benefits is understanding how different implementation models compare to each other and to other interventions with similar aims and objectives. Herein, we outline two approaches to aggregating outcomes for school-feeding. One involves a discreet choice experiment to derive utility scores combining outcomes into one measure. The other focuses on quality-adjusted school days as a measure that encompasses the varied benefits from schoolfeeding. The discrete choice experiment offers a robust method to integrate utility for different benefits. However, it necessitates a complex design. The quality-adjusted school days method has greater simplicity. When developed, different interventions that aim to foster learning could be meaningfully compared
