This document discusses sustainable skill development. It outlines four key blocks needed: infrastructure, delivery mechanisms, policy, and funding. It also identifies several aspects of sustainable skill development, including the multi-layered nature of skills and the need for continuous re-skilling. Key imperatives include demand-driven planning at national, state, and district levels, and reforms to primary education. National policies aim to skill large portions of the population to meet economic needs. However, existing vocational education faces issues like outdated curricula and weak industry linkages.
