Distance learning, on the other hand, is one particular form of open learning in which tutors and learners are separated by geographical distance. This is sometimes called a home study or correspondence course. But many modes of communication are used for distance learning, not just postal correspondence. If you stop to think about it, most of us use distance learning techniques in some form in our daily lives: we read books and newspapers, watch programs on television and request information over the telephone. These are all learning experiences which 'educate' in the broadest sense.

Open school is a system which is free of regular school's attendance, time bound programs. It is for those people who are not able to attend or could not attend regular school because of various reasons and now they want to complete their education in 10th or 12th regardless of age and some other reason they cannot join regular school programs.

It provide you the following facilities that a regular school does not have

1) Flexibility of choosing program independent of your age
2) Flexibility of not attending classes
3) Flexibility of on demand exam (You can give exam when you are ready)
4) Flexibility of time frame (You can do program of 1 year even in 4-6 year if you are not ready for exam)

At national level we are having NIOS with regional centres at state level.
