- Accredited Institutions (AIs) provide face-to-face support classes — attending is strongly recommended
Examination System
NIOS conducts two types of examinations:
- Public Examination — Traditional exam held twice a year (April and October sessions)
- On Demand Examination (ODE) — Available throughout the year for selected subjects; you appear when you feel ready
You have 9 chances to pass all your subjects within 5 years of enrollment.
Transfer of Credits (TOC)
If you previously passed some subjects in CBSE, ICSE, or a state board but failed others, NIOS allows you to transfer those credits. This means you only need to appear for failed subjects under NIOS — one of its biggest advantages for students who narrowly missed passing.
