The NIOS Syllabus 2026 covers Class 10 (Secondary) with 18+ subjects and Class 12 (Senior Secondary) with 30+ subjects. It's been revised to sit alongside NEP 2020. Every subject has an 80-mark theory paper and 20 marks for the Tutor Marked Assignment (TMA) or practical. The minimum passing mark is 33% per subject. Public exams happen in April and October, with the On-Demand Exam System (ODES) running alongside. You'll find the official syllabus PDFs on nios.ac.in.
Fast, clear and exam-focused overview before you start the full syllabus guide.
Class 10 has 18+ subjects. Class 12 has 30+. You pick five either way, and one of them must be a language.
Every paper splits the same way: 80 marks for theory, 20 for TMA or practical. Pass mark is 33% per subject.
The 2026 update lines up with NEP 2020. A handful of chapters in Science, Physics, Business Studies, and History have been trimmed.
Public exams run in April and October. The On-Demand Exam System fills the gaps — you can appear for a single subject almost any month.
Official PDFs sit on nios.ac.in under Secondary and Senior Secondary. Grab them before you buy a single textbook.
If you're starting your NIOS prep this session, the syllabus is the first thing to open — not the textbook. Skip that step and you'll spend weeks on material that never shows up in the paper. We see it happen every cycle. NIOS keeps things flexible. Skill-based. Aligned with NEP 2020. You study at your own pace, pick your subjects, and have five years to finish Class 10 or Class 12.

The 2026 updates are practical, not dramatic — a few Science and Social Science chapters revised, more weight on skill subjects, a cleaner TMA structure, and study material that's now fully digital for registered students.
NIOS is a government board under the Ministry of Education, set up in 1989 for students who, for one reason or another, can't be in a regular classroom. Its certificate is officially recognised — same weight as CBSE or any State Board when it comes to higher studies, jobs, and entrance tests.
According to nios.ac.in, more than four lakh students sign up every year. That makes NIOS one of the largest open-schooling systems in the world.
Twelve years of mentoring has taught us that five kinds of students keep coming through our door. If you're reading this, you probably fit one of them.
The common thread? If classroom pressure is getting in the way of your actual goals, NIOS gives you the breathing room to figure things out.
Short answer: NIOS has updated the 2026 syllabus to match NEP 2020. Less rote. More application. A few chapters trimmed, practicals cleaned up, vocational subjects expanded.
The longer answer — the one that actually matters when you're sitting with the textbook — has five specific changes worth knowing.
3.1 Science (212) and Physics (312): revised chapter sequencing
In Class 10 Science (212), motion and force now come before light and sound. It's a small reshuffle, but it helps the flow. In Class 12 Physics (312), electrostatics still opens the book, but two of the heavier derivations inside electromagnetic induction have been shortened. Numerical problems and applications now carry the load. Looking at the April 2026 TMA sets, derivations are clearly being given less weight than they were in 2024.
3.2 Social Science and History: digital literacy in, long war content out
Social Science (213) now has two short modules — one on digital literacy, one on personal financial awareness. They cover UPI, basic cyber safety, and compound interest explained through a simple household savings angle. Over in Class 12 History (315), the First and Second World Wars have been shortened considerably. The focus has shifted to what those wars meant for South Asia and decolonisation, which is a more useful frame for Indian students anyway.
3.3 Entrepreneurship (249) and Business Studies (319): case-based questions
Entrepreneurship (249) at Class 10 and Business Studies (319) at Class 12 now have proper case-based questions in the theory paper. The sample papers put them at 8 to 12 marks each. A typical prompt might be something like a small Delhi-based D2C brand running out of working capital — you have to identify the problem and suggest a response. If you've been preparing with pure definitions and flowcharts, this is the adjustment you'll need to make.
3.4 Practical weightage is now uniform
Until 2025, a few subjects had slightly different splits for their practical component, and that caused genuine confusion at submission. For 2026, it's standardised. Every practical subject — Physics, Chemistry, Biology, Home Science, Painting, Psychology, Data Entry Operations — carries 20 marks, split into the hands-on exercise, the file, and the viva.
3.5 On-Demand Exam System (ODES): wider coverage
ODES lets you appear for a single subject almost any month of the year, instead of waiting out an April–October cycle. For 2026, more subjects have been added to ODES at both Class 10 and Class 12, including a broader set of vocational options. If you're stuck with one backlog subject, this changes your timeline completely. No more six-month wait.
Mentor note: Across the roughly 1,200 students we're actively mentoring in any given session, nearly one in three uses ODES for at least one subject — and about four out of five of them clear the paper on their first ODES attempt. When a single subject is all that's holding up your certificate, ODES almost always beats waiting for the next public exam.
The 2026 curriculum notification is live on the NIOS website, and you can pull the exact chapter list for any subject straight from nios.ac.in. One more thing — if you're planning to register this year, don't miss the NIOS Admission last date 2026. Registration closes well before the exam window opens.
Before we get into the subject lists, here are the six abbreviations you'll run into constantly. Worth getting right, because they come up every time you read a circular or talk to a study centre.
TMA — Tutor Marked Assignment: Six questions per subject, done at home, submitted to your study centre before the exam deadline. Worth 20% of your final marks. Skip it and you can't sit the theory paper.
ODES — On-Demand Exam System: A flexible exam window that lets you appear for one subject almost any month of the year. Mostly used for clearing a backlog paper.
AIU — Association of Indian Universities: The body that decides which school boards count as equivalent. AIU treats NIOS as equivalent to CBSE, ICSE, and State Boards, which is why NIOS certificates work everywhere.
NEP — National Education Policy 2020: India's current education policy. Pushes school education away from rote and toward skills, flexibility, and real-world application. The NIOS 2026 syllabus is built around it.
Stream 1: The standard NIOS registration. Meant for students who plan to write the next public exam cycle and have time to cover the full syllabus and TMA.
Stream 2: A shorter route. For students clearing one or two subjects fast, usually compartment cases from another board. Quicker, but the documentation rules are stricter.
The nios syllabus for 10th is built to give students a solid base — languages, core subjects, and skill-based learning. You pick five subjects, and at least one has to be a language.

Hindi (201) covers prose, poetry, grammar, and essay writing. English (202) runs through reading comprehension, writing skills, grammar, and a literature section built around short stories and poems. Sanskrit, Urdu, and Punjabi are there too if you'd rather go regional — and they often end up being scoring subjects when the student already has some background in the language.
Maths (211) has nine units — Number Systems, Algebra, Geometry, Statistics, and so on. Science (212) combines Physics (motion, light, electricity), Chemistry (atoms, elements, acids and bases), and Biology (life processes, reproduction) into one paper. Social Science (213) pulls together History, Geography, Economics, and Political Science, and the 2026 version adds those short modules on digital citizenship and financial literacy we covered earlier.
Economics (214), Business Studies (215), and Accountancy (224) are the commerce triad — a clean foundation if you're heading toward commerce in Class 12. Home Science (216), Psychology (222), and Indian Culture (223) tend to attract students who prefer reading-heavy, concept-driven subjects over numbers and diagrams.
Painting (225), Data Entry (229), Music (242 and 243), Folk Art (244), and Entrepreneurship (249) are solid picks for students who want subjects that are both scoring and genuinely interesting. Most of them come with practicals, and that's usually where easy marks get picked up.
Parts of Science, Social Science, and Maths have been cut for the 2026 cycle. Based on the circulars published this year and the TMA sets we've seen at Unnati Education NIOS, here's what's out of scope right now:
Circulars do get refreshed between cycles, so always cross-check the final chapter list on nios.ac.in before you settle into theory prep.
Subject-wise PDFs are on the NIOS website. Our team also maintains a verified NIOS class 10 study material library with notes, TMAs, and NIOS previous year papers if you want everything in one place.
If this is your first NIOS application, read our NIOS Class 10 Admission process guide — it walks through fees, documents, and the registration timeline.
The nios syllabus for 12th is broader because you're now picking a stream — Science, Commerce, or Arts. Five subjects total, one language mandatory. What sets NIOS apart is that it doesn't lock you into a stream. Physics, Psychology, and Tourism can all sit on the same mark-sheet if that's what your career plan needs, and that's genuinely useful.
| Subject | Code |
|---|---|
| Hindi | 301 |
| English | 302 |
| Mathematics | 311 |
| Physics | 312 |
| Chemistry | 313 |
| Biology | 314 |
| History | 315 |

Physics (312) covers electrostatics, current electricity, magnetism, electromagnetic induction, optics, and modern physics. Chemistry (313) is split three ways — Physical, Organic, Inorganic. Biology (314) focuses on reproduction, genetics, evolution, and ecology. Maths (311) brings in Calculus, Algebra, Vectors, and Probability. The combination meets NEET and JEE eligibility, so NIOS Science students aren't at any disadvantage at the entrance level.
Accountancy (320), Economics (318), and Business Studies (319) are the commerce backbone. Maths (311) is optional, but we'd recommend it for anyone targeting B.Com honours or CA Foundation.
History (315), Geography (316), Political Science (317), Psychology (328), Sociology (331), and Public Administration are the usual picks. They line up well with UPSC prep, law entrance exams, and mass media programmes.
Hindi (301) and English (302) are by far the most picked. Sanskrit, Urdu, and regional languages are also available, and they're often easier to score in when you already have everyday familiarity with the language.
Mass Communication (335), Tourism (337), Introduction to Law (338), Environmental Science (333), Data Entry Operation (336), and Library Science (339) point you toward career-focused paths. They're useful for students who want to start earning within a year of Class 12, or who want to pair a regular undergraduate degree with a work-ready skill.
A handful of units in Business Studies, History, and Physics have been trimmed for this session. Based on the current circulars and the April 2026 TMA sets, here's what's out:
Confirm the exact removals for your subject from the latest NIOS circular on nios.ac.in — small adjustments sometimes appear between the April and October cycles.

Question types: MCQs, short answers, long answers, case-based.
TMA is 20% of your final marksheet — not something to skip. For the latest question paper format, request the NIOS Solved Question Paper from our team.
TMA stands for Tutor Marked Assignment. 20% of your final result. Miss it and you can't sit the theory exam — a lesson most students learn about a week before the paper, unfortunately.
Each subject has six questions in the TMA booklet. You submit the completed assignment to your study centre before the deadline printed on your hall ticket. If you need ready-to-submit versions, we've got typed and handwritten TMAs for every Class 10 and Class 12 subject.
Mentor note: Across the last five sessions, the single biggest reason students couldn't write the theory paper — despite being fully prepared — was a missing or rejected TMA. Submit it at least two weeks before the deadline, keep a photocopy, and hold on to your study centre receipt.
Practical subjects include Physics, Chemistry, Biology, Home Science, Painting, Data Entry, and Psychology.
Three mistakes come up again and again, and all three are avoidable:

Pick subjects based on where you're going, not what looks easy today.
Here's a plan that actually works. We've refined it with Unnati students across more than a dozen sessions.
Recommended daily study time: 2–3 hours for Class 10, 3–4 hours for Class 12. Consistency beats weekend marathons every time.
Official syllabus PDFs live on nios.ac.in under the Secondary and Senior Secondary sections. For faster access — chapter-wise mapping, verified mirror links, solved TMAs included — you can request the full set from our team.

Once you're done with the syllabus, here's the checklist:
NIOS students are eligible for almost every public and private university in India.
All three are real students we worked with at Unnati Education NIOS.
The NIOS syllabus 2026 is the updated curriculum NIOS has released for Class 10 and Class 12, aligned with NEP 2020. It includes revised chapters, updated TMA questions, refreshed practical guidelines, and expanded vocational subjects. You'll find the official version on nios.ac.in, and our team at Unnati Education NIOS can send you the subject-wise PDF if you need faster access.
The NIOS syllabus covers the same core concepts as CBSE, but it's structured for self-paced learning. Maths, Science, and Social Science share the same fundamentals, though NIOS uses simpler language and a slightly lighter content load. Where NIOS genuinely differs is in exam flexibility, TMA weightage, and pacing — which is why working learners tend to find it easier to manage.
NIOS Class 10 offers more than 18 subjects — languages, academic subjects like Maths and Science, and skill-based options like Painting, Data Entry, and Entrepreneurship. You have to pick five, and at least one has to be a language. The structure gives you real room to build a combination that actually matches your interests and goals.
NIOS Class 12 has over 30 subjects across Science, Commerce, Arts, and vocational streams. You pick five, with one language mandatory. Unlike most boards, NIOS lets you mix streams — Physics with Psychology, or Business Studies with Mass Communication. No special approval needed. That flexibility is a big reason students pick NIOS over traditional boards at senior secondary level.
The minimum passing mark is 33% per subject — calculated from the combined theory and TMA or practical score. You have to pass both components to clear the subject. If you fall short, you can re-attempt the same subject in the next cycle or through ODES, without repeating the whole year. That's a significant advantage compared to most other boards.
The official NIOS syllabus PDFs are on nios.ac.in under the Secondary and Senior Secondary sections. If you'd rather skip the navigation — and get subject-wise mapping plus solved TMAs bundled in — our team at Unnati Education NIOS can send the complete 2026 set directly. No charges, no wait.
Yes. NIOS has trimmed specific chapters in Science, Physics, Business Studies, and History for 2026. Examples include reduced derivations in Physics (312) — particularly electrostatics and electromagnetic induction — and a shorter treatment of the world wars in History (315). Deletions vary by subject, so check the latest circular on nios.ac.in for a complete list before starting your prep.
Generally, yes. The language is simpler, chapters are shorter, and TMA contributes 20% to your result, which softens the theory paper pressure. Questions tend to be direct and concept-based. But the pass mark and official recognition are identical to CBSE — so NIOS is every bit as valid for higher studies, entrance exams, and jobs.
TMA stands for Tutor Marked Assignment. It's 20% of your final marksheet. Each subject has six questions you submit to your study centre before the exam deadline. Skip the TMA and you can't sit the theory paper — it's non-negotiable. Students who put real effort into their TMAs (neat, complete, well-written) often pick up six to ten extra marks without breaking a sweat.
Yes. NIOS lets you change one or more subjects after registration — there's a small subject-change fee. It's genuinely useful if you picked a subject that turned out to be harder than expected. The change request has to be in before the exam form deadline. Our team at Unnati Education NIOS can walk you through the process if you need help.
Yes. NIOS Class 12 is fully valid for NEET, JEE Main, JEE Advanced, CUET, and every major entrance exam in India. You'll need the right subject combination — Physics, Chemistry, Biology (or Maths) for NEET, for example. NIOS certificates are recognised by NTA, MCC, AICTE, and AIU. Plenty of doctors and engineers in India today cleared Class 12 through NIOS.
Practical subjects include Physics, Chemistry, Biology, Home Science, Painting, Psychology, and Data Entry. Each practical is 20 marks — split between file submission, viva, and actual practical performance. The topics are laid out in the official NIOS lab manual. If you want ready-to-submit files formatted exactly the way examiners expect, our team at Unnati Education NIOS can provide them.
NIOS reviews the syllabus every year, factoring in NEP 2020, expert committees, and student feedback. Updates go out through official circulars on nios.ac.in before the registration window opens. Most changes cover chapter revisions, TMA updates, and practical format tweaks. It's worth verifying your subject syllabus at the start of each session — you don't want to prep from outdated books.
NIOS offers its syllabus in English, Hindi, and Urdu for most subjects, with regional language options for certain courses. You pick your medium during admission, and your textbooks, TMAs, and question papers all come through in that medium. It's particularly helpful for students from rural areas, non-English backgrounds, and regional schools — the language barrier disappears.
Yes. The entire NIOS syllabus 2026 is aligned with NEP 2020 — skills, flexibility, and real-world application over rote learning. Vocational subjects have been strengthened, chapters have been simplified, and the assessment now leans more on conceptual and case-based questions. It's arguably one of the most modern and student-friendly boards in India right now.
NIOS students are eligible for almost every public and private university in India. From choosing subjects to understanding assignments and exam patterns, Unnati Education walks with you at every step. Across the roughly 1,200 students we're actively mentoring in any given session, nearly one in three uses ODES for at least one subject — and about four out of five of them clear the paper on their first ODES attempt. When a single subject is all that's holding up your certificate, ODES almost always beats waiting for the next public exam.
