Designed as a step-by-step guide, this handbook shows how ADB-backed infrastructure projects in Asia and the Pacific can integrate employability and skills development by delivering work-based youth traineeship opportunities that amplify project benefits. It provides practical guidance for project processing teams and implementation units including templates for direct use. It also sets out how to weave cost-effective traineeships into project procurement documents and deliver training programs. The handbook shows how integrating traineeships into projects requires marginal budget increases and explains why offering work-based training helps build a more skilled and productive workforce that improves youth inclusion and boosts employability.
