Hello aspirant,

A legitimate and reputable board is the National Institute of Open Schooling. Results are applicable throughout India. All Indian educational institutions and universities completely acknowledge NIOS, which was founded in 1989 by the Ministry of Education, Government of India. Therefore, a student who completed their education through the NIOS board is qualified to enroll in any college or university in India without any bother or fuss.

Thank you

Hope it helps you.
