The Central Board of Secondary Education (CBSE) has issued a crucial marks distribution circular for the 2026 board exams (Class 10 and Class 12), detailing how marks will be allocated across theory exams, practicals, projects, and internal assessments (IA). The official notification—published on 23 October 2024—provides subject-wise maximum marks for each assessment component to ensure schools upload accurate scores and avoid discrepancies.
This updated marking scheme reflects important changes aligned with the New Education Policy (NEP 2020), emphasizing competency-based assessment and a balanced approach between written exams and practical/internal evaluation.
What the CBSE Circular Says
The CBSE circular confirms that the maximum marks for each subject remains 100.
Marks are distributed among theory, practical, project work, and IA as per subject requirements.
CBSE has also warned schools to upload correct marks carefully, stressing that once uploaded, they will not be changed.
For subjects with practical or project components, CBSE provides details on whether an external examiner will be appointed and whether the board will supply the practical answer book.
Class 10 Marks Distribution for 2026
According to career-education portals summarizing the CBSE scheme, here is the distribution for Class 10:
| Subject | Theory Marks | Practical / IA / Internal |
|---|---|---|
| Hindi (Course A / B) | 80 | 20 |
| English (both types) | 80 | 20 |
| Mathematics (Standard / Basic) | 80 | 20 |
| Science | 80 | 20 |
| Social Science | 80 | 20 |
| Computer Applications | 50 | 50 (Practical) |
These changes ensure that even for non-practical subjects, internal assessment has a significant role (20 marks) in the final score.
Class 12 Marks Distribution for 2026
CBSE has also shared detailed marks distribution for Class 12 subjects for theory, practical (or project), and internal assessments. Below are key subjects and their mark splits:
| Subject (Class 12) | Theory Marks | Practical / Project / IA |
|---|---|---|
| Physics, Chemistry, Biology, Computer Science | 70 | 30 |
| Mathematics | 80 | 20 |
| English (Core / Elective) | 80 | 20 |
| Commerce (Accountancy / Business Studies / Economics) | 80 | 20 (Project or IA) |
| Political Science, History, Sociology | 80 | 20 (Project / IA) |
| Geography | 70 | 30 (Practical) |
This distribution shows that major science subjects (like Physics, Chemistry, Biology) continue to carry a 30-mark weight for practical.
Why These Changes Matter
Greater Clarity for Schools
The circular helps schools correctly upload marks for practicals, projects, and internal assessment — avoiding errors and confusion.Competency-Based Assessment
For Class 12, CBSE has increased the weightage of competency-based questions and case-based assessments. This aligns with NEP 2020’s goal of evaluating understanding, application, and analytical thinking rather than rote learning.Balanced Evaluation
With 20–30 marks allotted to practical or internal work, students’ performance in hands-on activities matter significantly, promoting holistic evaluation.Strict Data Upload Rules
Since CBSE warns that marks once uploaded cannot be changed, teachers and school administrators must be vigilant while entering scores.
Important Passing Criteria
According to CBSE’s FAQ, for subjects with practical, students must score at least 33% in theory and 33% in practical separately, and also at least 33% in aggregate to pass.
For non-practical subjects, the overall minimum is also 33%.
This ensures students cannot pass by scoring high in one component only — balance is required.
Special Notes & Highlights
Practical Exams Timeline: For the 2026 session, practical exams are set to begin from 1 January 2025.
Winter-Bound Schools: In some cold-region schools (“winter-bound”), practicals may begin as early as 6 November 2025.
No Changes to Total Marks: Even after restructuring, the total marks per subject remain 100.
What Students Should Do
Check the CBSE Circular: Visit the CBSE website and download the Marks Distribution Circular to cross-verify marks for your subjects.
Discuss with Teachers: Ensure your school staff is aware of the new evaluation criteria and properly uploads your internal/practical marks.
Revise Accordingly: Focus on practical-related subjects more than before; your effort in lab work and internal assessment now has a higher weightage.
Prepare for Competency Questions: For Class 12, emphasize application-based reasoning and case studies.
Understand Passing Rules: Knowing that in practical subjects you need to pass both theory and practical helps plan how much to aim for in each component.
Final Thoughts
The CBSE 2026 marks distribution circular is a key document guiding how board exams will be graded for Class 10 and Class 12. With a clear split among theory, practical, and internal assessments, students, teachers, and parents now have better clarity and can plan preparation accordingly. The new format, aligned to NEP 2020, prioritizes understanding and real-world application over simple memorization.
If you’re appearing for the 2026 board exams, make sure to download the circular, revisit your strengths and weaknesses, and allocate study time according to the marks distribution.
