NIOS is “Open School” to cater to the needs of a heterogeneous group of learners up to pre-degree level. It was started as a project with in-built flexibilities by the Central Board of Secondary Education (CBSE) in 1979. In 1986, the National Policy on Education suggested strengthening of Open School System for extending open learning facilities in a phased manner at secondary level all over the country as an independent system with its own curriculum and examination leading to certification.
The NIOS provides resource support (such as adaptation of NIOS model curricula, study materials, joint certification, orientation of Resource Persons and popularisation of OBE) to the voluntary agencies and Zila Saksharta Samities (ZSSs) etc., for implementation of its OBE programme.
