This document discusses lessons learned from an early grade evaluation in South Africa conducted during the COVID-19 pandemic. The evaluation had four objectives: two impact evaluations, COVID-19 research, and establishing language benchmarks. Large scale data was collected in schools, and the document outlines how to use the data intentionally for decision-making to support teachers, principals, and parents. It also discusses making the data timely, sharing it through various repositories, and learning from the data through collaboration, dialogue, and taking action.
