Hii,
NIOS is a recognised board set up by the Ministry of Human Resource Development (MHRD), Government of India. It is equivalent to another academic recognized board like as CBSE, ICSE etc.
Hope it helps!!!
The value of open schooling is like any other board. The plus is the vocational skills that a student develops as he/she studies in the course duration the same which others also take. It makes education accessible to even the marginalized sections of people.
