What’s Changing? CBSE Overview
| Reform | Class | Details |
|---|---|---|
| Twice-a-Year Board Exams | Class 10 | Both exams mandatory; second for improvement/compartment |
| Subject Improvement Option | Class 10 | Improve up to 3 subjects (Science, Maths, SST, Languages) |

Class 10: Two Board Exams Starting 2026
From 2026, CBSE will conduct Class 10 Board Examinations twice a year. The first exam is mandatory for all students. Those who clear it can choose to improve their scores in up to three subjects — Science, Mathematics, Social Science, or Languages.

Students who land in the Compartment category after the first attempt will get a second chance through the second examination under the compartment scheme. This is a student-friendly move that reduces exam pressure and gives learners a fair shot at improvement. Learn more about how board exams work on Wikipedia’s page on CBSE.
Class 12: Going Digital with On-Screen Marking (OSM)
For Class 12, CBSE is transitioning to a digital On-Screen Marking system — a game changer for accuracy and efficiency. Here’s why OSM matters:
- No totalling errors — automated calculation reduces human mistakes
- Faster results — wider teacher participation speeds up evaluation
- Eco-friendly — reduces paper usage and transport costs
- Global reach — overseas affiliated schools can also participate
- No post-result verification needed — saving time and manpower
This shift mirrors global best practices and positions CBSE among modern examination boards worldwide.
Subject-wise Evaluation for Class 10
For Science and Social Science, answer scripts will now be evaluated subject-wise by concerned experts. This ensures specialised, accurate assessment rather than a one-size-fits-all approach — a much-needed upgrade for technical subjects.
📌 Note: Class 10 answer books will still be evaluated in physical mode in 2026, with digital evaluation expected in future phases.
