The role of Civil Society Organisations (CSOs) in Human Capital Development (HCD) and Lifelong Learning (LLL) is more critical than ever in addressing the challenges of a rapidly changing world. These organisations bridge educational gaps, promote inclusivity, and empower individuals through innovative approaches to learning and employment. The European Training Foundation's thematic paper, "The Role of Civil Society Organisations in Human Capital Development and Lifelong Learning," highlights how CSOs: (1) Advocate for inclusive learning opportunities for all, especially vulnerable groups; (2) Drive innovation through new teaching methods and technology; (3) Build partnerships with governments, educators, and businesses to amplify impact; and (4) Empower communities by fostering active participation and civic engagement. Based on European Training Foundation (ETF) studies implemented in Albania, Jordan, Serbia, Tajikistan, Ukraine, and Uzbekistan, the paper underscores the vital role of CSOs and calls for stronger collaboration to shape equitable and sustainable HCD and LLL strategies worldwide
