This practice guide aims to help procurement practitioners integrate youth traineeship specifications into key bidding documents for ADB-supported infrastructure projects in Asia and the Pacific. Designed to complement the Build4Skills Handbook, it details how to select which projects could potentially incorporate trainee programs and provides templates for projects in the energy, transport, water, urban, and social sectors. Explaining how to calculate traineeship cost estimates to be included in the bill of quantities and manage related disbursements for projects, the guide shows how to monitor trainee programs and collect feedback to ensure infrastructure projects maximize their skills development potential.
