Education through open and distance system is perhaps the only way to reach out to a large number of people who cannot pursue their academic and professional skills because of geographical, physical and time constraints. 

Open and distance learning has been recognised as one of the ways for individuals to pursue skills, become empowered and contribute to social and economic development of the country. With the advent of multimedia and internet based learning solutions, open and distance learning has acquired new meaning.
