Data insights
Valued principals focus on instruction and engagement with students, parents and the community
School principals who keep teaching and learning at the centre of their work are highly valued by teachers. They use school and classroom assessment results to inform teacher appraisal, follow appraisal with teacher development plans, observe classroom teaching, provide feedback to teachers and support collaborative decision making. Principals who engage with students, parents and the local community are also perceived as stronger leaders. However, trends in the use of these leadership practices are mixed. For example, student participation in school decision making grew in most education systems between 2018 and 2024, while principals’ use of school and classroom results in teachers’ formal appraisal declined over the period.

Artificial intelligence (AI) is a transformative technology capable of tasks that typically require human-like intelligence, such as understanding language, recognising patterns, and making decisions. AI holds the potential to address complex challenges from enhancing education and improving health care, to driving scientific innovation and climate action. But AI systems also pose risks to privacy, safety, security, and human autonomy. Effective governance is essential to ensure AI development and deployment are safe, secure and trustworthy, with policies and regulation that foster innovation and competition.Learn more

Global value chains (GVCs) account for about 70% of international trade, as services, raw materials, parts, and components cross borders – often multiple times. As the trend toward cross-border supply chains increases, new challenges are emerging around sustainability, efficiency, and resilience. This growing complexity calls for policies that take a whole-of-chain approach to supply chain management and global trade.Learn more
