NIOS is the only education board in the country that delivers secondary and senior secondary education in 14 languages. Due to the Covid situation, NIOS too could not conduct its Board exams as well as on-demand exams in 2020 and 2021. Annually it conducts Board exams for around five lakh candidates.
