Resource banks support learning in classrooms by improving the quality of teacher instruction and assessment. They are typically online platforms that include examples of curriculum-aligned assessment tasks and complementary instruction, assessment and learning materials. These can be used by teachers, students and parents to improve learning in schools. While resource banks have become an important curriculum and assessment tool in many OECD countries, information about them remains scarce. This policy perspective provides a framework to help educators plan, design and use resource banks. First, policymakers should have a thorough concept of the resource bank and carefully plan its governance and resourcing structure. Second, the definition and development of its content and the platform’s underlying technology should be guided by quality, security and privacy principles that place users at the centre. Thirdly, once released, it is important to promote awareness of the resource bank to key stakeholders and maintain content and IT-support. This will ensure resource banks have a long-lasting and positive impact on educational practices.
