This Education Spotlight, the last in a series of three, presents key lessons and inspiring examples of policy and practice to inform how higher education systems can support and promote upskilling and reskilling of adult learners to contribute to green and digital innovation. The Spotlight was prepared by the OECD Higher Education Policy Team as part of the Education and Innovation Practice Community (EIPC), an action of the European Union’s New European Innovation Agenda, flagship 4 on “Fostering, attracting and retaining deep tech talent”. The EIPC seeks to bring together peers from policy and practice to advance understanding of the competencies that can support and shape innovation for the digital and green transitions, as well as the mechanisms through which higher education can contribute to their development in secondary education, higher education, and adult upskilling and reskilling.
