Equity and evidence are at the heart of our approach. We support the Principles for Digital Development. We use ‘open’ (content, access, software, standards) to achieve scalability and sustainability. We use agile and adaptive management, driven by a Theory of Change. We draw on technology where it offers the best value proposition. We offer a needs-sensitive working environment that puts people at the centre.

  • Rigorous education research
  • Efficient education programme implementation
