ABOUT THE PROGRAMME

The unorganized sector is an important part of the Indian economy. The unorganized sector consists

of all un-incorporated private enterprises owned by individuals or households engaged in production

and sale of goods and services operated on a proprietary or partenership basis having less than ten

workers. This sector contributes to approximately 92% of total employment and 55% of the GDP of

the country. This sector also makes significant contribution to exports. In view of its contribution toemployment generation, exports and accelerating the pace of economic development in the country,

the manpower engaged in unorganized sector deserves special attention of our planners and policy

formulators. The unorganized sector in India also takes within its fold the informal employment/

unorganized employment. A close look at various sectors of Indian economy reveals that the

organized sector also avails the services of a huge population of informal workers. The informal

workers/unorganized employees working in organized sectors of Indian economy are usually the

contractual employees engaged in providing services like security, housekeeping, catering, cleanliness,

transport, material handling, gardening, data processing etc. Such workers of Indian economy are

usually deprived of social security and variety of other benefits enjoyed by the regular employees. It

is, therefore, in this context that the persons working in the vast unorganized sector as well as

informal/unorganized employees working in organized sectors of Indian economy need to be

considered at an equal platform. They also deserve special attention of those who are involved in

training and developing manpower for the unorganized sector. It has also been observed that 60-65 %

of employees working in organized sectors falls under the category of informal/unorganized

employment in the formal sectors. From employment perspective, the informal sector emerges as the

largest sector of the Indian economy and its skill requirements are also diverse which are large in

quantity in comparison to any of the organized sectors.

The National Skill Development Corporation [NSDC] with the help of the established consultants has

studied the present and future manpower requirement of the vast Indian informal sector. The skill

pyramid of this sector evolved by the NSDC has been studied thoroughly and manpower requirements

particularly at level I and II have been looked into in detail. Accordingly, an attempt has been made to

evolve curricula for various trades falling under the Unorganized Sector/Unorganized Employment in

the Organized Sectors in India.

This curriculum has been tailor-made which suits to the requirements of the intended target groups. It

is hoped that the instructional resources developers, training providers and the training assessors

would make use of this curriculum document in imparting quality training to the intended target

groups.
