CBSE Class 10 Pass Marks 2027: What the Official Notices Say About the 33% Rule
CBSE says the Class 10 passing criteria for 2026-27 stay the same as 2025-26. What that means for your child, and what is still unclear.
Short answer for worried parents: CBSE has said in a September 21, 2026 notification that the passing criteria for 2026-27 remain the same as 2025-26. In 2025-26, Class 10 students needed 33% overall in each subject, with board exam and internal assessment marks combined. But the 2026-27 curriculum document words the rule differently, so read the details below and check with your school.
What happened
CBSE's Secondary Curriculum 2026-27 says that to be declared successful in a subject, a student must secure a minimum of 33% marks separately in external and internal assessments. The 2025-26 curriculum said students have to secure 33 percent in total, combining the 80-mark board exam and 20-mark internal assessment, and CBSE's FAQ says the same for Class 10. Then, in a notification dated September 21, 2026 about sample papers, the board said there is no change in the question paper design or assessment pattern for 2026-27, and that the passing criteria will remain the same as in 2025-26.
EdexLive (October 1, 2026) reports this as CBSE dropping the subject-wise 33% criterion for 2026-27. We could not find CBSE's own notification stating that the curriculum wording was withdrawn, so treat that part as a news report and ask your school which rule it is following.
The rule that applies to your child
| 2025-26 rule, which CBSE says continues in 2026-27 | Wording in the 2026-27 curriculum document | |
|---|---|---|
| What you need | 33% overall in each subject (board exam plus internal assessment combined) | 33% separately in the board exam and in internal assessment |
| Can strong internal marks cover a weak written paper? | Yes, because the two are added | No, each part had to cross 33% |
| Exam pattern for 2026-27 | Unchanged | Unchanged |
For most Class 10 subjects, the split is 80 marks for the board exam and 20 for internal assessment. So under the current rule, a child who scores 25 out of 80 in the board paper and 17 out of 20 internally has 42 out of 100 and passes that subject. Under a separate-33% reading, 25 out of 80 would be below the 33% mark for the board part alone. This example is only an illustration of the arithmetic, not an official CBSE case.

Why it is worth watching
EdexLive also reports that the change could be considered again for 2027-28, which we could not confirm from a CBSE document. Either way, do not treat internal assessment as a formality.
What to do now
- Do not panic over forwarded messages about a stricter rule. CBSE's own notice says the passing criteria are unchanged for 2026-27.
- Still take internal assessment seriously. Those 20 marks are the easiest to protect, and they help if a written paper goes badly.
- Use the sample papers and marking schemes CBSE publishes to practise the real paper format.
- Confirm any rule from the board's own notices on cbse.gov.in, not from a social media post.

Ask how the school supports internal assessment, practicals and project work. Schools that treat these seriously protect your child's overall marks. Also read how the two-exam model works.
