CBSE 2026-27: what actually changed, and what did not

If you set CBSE papers, September is the month the year actually starts. Here is what is confirmed for the 2026–27 session, what is still unpublished, and — most usefully — which widely shared “news” is about a session that has already finished.

How this post is sourced. Everything below was checked against a live source on 22 September 2026. Where something is reported rather than officially published, it says so. Anything we could not verify is not in this post at all.

1. The 2026–27 sample papers are already out

CBSE has published the Sample Question Papers and the Marking Schemes for Class 10 and Class 12 for the 2026–27 session on cbseacademic.nic.in. They went up in September 2026.

This is the single most useful thing on this list and the one most teachers act on last. The sample paper plus its marking scheme is the authoritative blueprint for the 2027 boards. It is not a publisher’s interpretation and it is not last year’s paper with the year changed on the cover. If you are planning a term paper, a revision set, or a question bank for the year, that is the document to build from.

One detail worth checking before you plan

As of late September 2026, a number of subjects on both the Class 10 and Class 12 pages were still linking to an error page rather than a paper — several regional languages among them, including Tamil. If you teach a language subject, check that your own paper is actually up before you schedule revision around it. This may well be fixed by the time you read this; it had not been in late September.

2. Class 10 has two board exams — and Class 12 does not

This is real, notified policy, not a proposal. CBSE issued the notification in June 2025. As notified:

• The first examination is compulsory.
• The second is optional, and the better of the two results counts.
• Improvement is limited to a small number of subjects rather than the whole set.
• Internal assessment is conducted once, before the main exam — a student sitting the second attempt carries the same internal marks across.
• Both attempts cover the full syllabus. The second is not a reduced paper.

It applies to Class 10 only. There is no two-exam scheme for Class 12, however often the two get written about together.

The practical consequence for a teacher is the one nobody mentions: you now need a second full set of practice material that covers the entire syllabus, at a point in the year when you used to be finished. Whatever you use to produce papers, you will need roughly twice as many of them.

3. Be very careful with the dates you are being shown

This is the part to get right. Almost every article circulating at the moment that quotes February and May dates for the two Class 10 attempts is describing the 2025–26 session. Those exams have already been held. They are history, not a schedule.

As of late September 2026, CBSE had not published the dates for the two 2026–27 attempts, and had not released the 2027 date sheet for either class. Both are expected in the coming weeks. When you need them, take them from cbse.gov.in rather than from an aggregator — aggregators are where last session’s dates get quietly recycled with this session’s heading.

4. Open-book assessment in Class 9 is recommended, not mandatory

Open-book assessment enters Class 9 from this 2026–27 session, aligned to NCF-SE 2023. Two things about it are widely misreported:

• It is recommended, not compulsory. Schools opt in based on their own readiness.
• It applies to internal school assessment — not to the Class 10 board exam.

If your school does adopt it, the change in your workload is not the exam, it is the question. An open-book question that can be answered by finding a line in the chapter is not an open-book question; it is a slower closed-book one. Writing questions that survive the book being open is a genuinely different skill, and it is worth starting on a low-stakes test rather than a term paper.

5. New NCERT books for Classes 9 and 11 this session

The NCF-SE rollout puts new NCERT textbooks in front of Class 9 and Class 11 this year, with Classes 10 and 12 reported to follow. If you keep your own question bank — a folder of papers, a shared drive, a set of typed-up exercises — this is the year it stops matching the book in front of the class. Chapters move, exercises change, and a question filed under the old chapter number is now filed under nothing.

It is worth doing that audit deliberately rather than discovering it question by question while setting a paper in December.

What we would do with this, in order

1. Download your subject’s 2026–27 sample paper and marking scheme now. If it is a language and it is missing, check again in a week.
2. Assume you are producing roughly twice the practice papers for Class 10 this year.
3. Do not put any 2027 exam date in a letter to parents until it is on cbse.gov.in.
4. If you teach Class 9 or 11, audit your existing question material against the new book before the first unit test, not after.

Where we stand on CBSE: Examaker does not generate CBSE papers yet — it launches in the next few weeks, and the templates are being built against exactly the sample papers described above. The CBSE page says where it stands, and the board list says the same for every other board. Tamil Nadu State Board is live today.
