Data can be a powerful resource for education reform. Without it, education leaders can be immobilized because they do not have enough information to recognize that problems exist or to make the case for change. However, data only provides value if it is used to inform decisions. Unfortunately, many education systems struggle with this step. So, how can education leaders best be supported to use data to make better decisions in support of quality education improvements? In collaboration with local partners, IREX is supporting the development of data systems and tools to improve education systems through better, evidence-based decision-making.
