Schools2030 is a ten-year participatory learning improvement programme based in 1,000 government schools across ten countries. Our goal is to equip young people with the knowledge, skills, attitudes and values they need to becoming contributing and thriving members of their societies. We do this through a focus on teacher agency: recognising and amplifying teachers as leaders, innovators and active agents in education reform. Using the principles of human-centred design and focusing on the key transition years of ages 5, 10 and 15 years old, Schools2030 supports teachers and students to design and implement education micro-innovations. These low-cost and scaleable innovations are informing and transforming education systems to improve holistic learning outcomes for the most marginalised learners worldwide.
