In a key update for students preparing for the CBSE Class 12 board exams 2026, the Central Board of Secondary Education (CBSE) has clarified the rules for the supplementary improvement examination. According to the board’s exam controller, students who have passed Class 12 may now appear in the **supplementary (improvement) exam in only one subject to improve their marks or performance.
This new policy applies to the July 2026 supplementary session that follows the main board exams and aims to give passed students a chance to better their performance, but only in one subject — not multiple subjects in the same cycle.
📌 What the CBSE Rule Means
- Only one subject: Students who passed the Class 12 board exams 2026 can register to appear in the **supplementary improvement exam in **one subject only.
- Main vs Supplementary attempt: If a student wants to improve in more than one subject, they must reappear in the main board exam in the next academic cycle.
- Supplementary exams timing: The July 2026 session is expected to host these improvement exams after results of the main board test are announced.
This is an important distinction from previous years when some pathways allowed broader choices for improvement or additional subjects. Students and parents should plan strategically based on this guidance.
🧠 Who Is Eligible?
Students that fall into the following categories generally become eligible for the improvement attempt:
- Students who passed all subjects in the main board exam but wish to improve their performance in a chosen subject.
- Students should check the official CBSE circular and instructions released after the main result announcement for complete eligibility, application steps, dates, and fees.
Note: CBSE does not allow improvement in multiple subjects in the same supplementary session.
📆 How It Works (Tentative Timeline)
| Event | Expected Timing |
| Main CBSE Class 12 Exam | February – March 2026 |
| Main Result Declaration | After exam cycle (TBA) |
| Supplementary/Improvement Forms | Post results (TBA) |
| Supplementary Exam | July 2026 (Tentative) |
Final dates will be published by CBSE on the official portal.
📌 Important Points Students Should Know
✏️ One Subject Only
You may choose only one subject in which you want to improve your performance during the supplementary improvement exam in July 2026.
🧠 More Than One Subject?
If you wish to improve multiple subjects, you will need to appear in the main board exams again in the next cycle, because the supplementary policy allows only one improvement paper per student in a given cycle.
📜 Supplementary vs Compartment
The supplementary improvement exam is different from a compartment exam — which is held for students who did not pass one or more subjects. Improvement is for passed students who want to raise marks.
