NIOS: the syllabus we hold, and where every line came from
We hold 7 syllabuses for NIOS, edition 2023, read off 7 official documents published by National Institute of Open Schooling. That is 48 chapters and 217 topics. 5 of the 7 have passed every check we run, and the table below says which, and what is still open on the rest.
Everything here is the board's own document. We do not summarise a circular, we do not repost a date somebody put on a forum, and we do not print an examination date we have not read off the board. Each line names the file, the day we read it, and the hash of the exact bytes, so you can open the same file and check us.
The documents this was read from
Each one is the file the board published, fetched whole and hashed. The link goes to the board, not to a copy of it on our site.

Subject by subject, and what is still open
A syllabus is published the moment we have read it off the official document, with how well we know it said on its own row. Nothing is hidden until it is perfect.
| Class | Subject | What we hold | How well we know it |
|---|---|---|---|
| Class 10 | Mathematics | 6 chapters, 26 topics | Official NIOS 2023, verified |
| Class 10 | Science and Technology | 7 chapters, 32 topics | Found on the board's site, still checkinga chapter name could not be matched word for word in the document |
| Class 10 | Social Science | 4 chapters, 28 topics | Official NIOS 2023, verified |
| Class 12 | Biology | 5 chapters, 31 topics | Official NIOS 2023, verified |
| Class 12 | Chemistry | 8 chapters, 32 topics | Found on the board's site, still checkinga second reader disagreed with how the first one split the document, so the chapter list is not settled |
| Class 12 | Mathematics | 10 chapters, 38 topics | Official NIOS 2023, verified |
| Class 12 | Physics | 8 chapters, 30 topics | Official NIOS 2023, verified |
What is not here
- 2 of the 7 are still being checked. They are published with that said on their own row rather than held back, because a chapter list read off the official document is worth more to you than an empty page.
- No examination date sheet. We hold none as a document, so no page here carries one, in any form. When we hold one it will sit in the table above with a date and a hash like everything else.
Everything on this page was last checked on 3 September 2026.
