Synopsis In the developed word the percentage of literacy is very high since long but due to change in methods of production and the increase in the quantum of knowledge in the world has made it very necessary that workers are acquainted with the latest developments in the field of industry and work. For this purpose it has been felt that there is a great need for distance education. In the developing world the percentage of literary is quite low and the developing countries are trying to make more and more people literate. But due to shortage of funds it is not possible to provide education for every man. The first target of the developing countries is to reach a level of literacy in the shortest possible time for the maintenance of standards in industry and for providing the stability to the democratic systems of Government. This is why more and more open schools and open Universities are being started by the Governments of the developing world, especially in India almost every state has an open university which caters to the people who did not get opportunity to go to the university due to financial considerations as well as other considerations. Similarly, the open schools are providing the opportunity to every school going child to get education through distance education. It is expected that the book will be found to be of immense use by the educational planners, administrators and the general public alike.
