India's school education is going through its biggest overhaul in decades. The National Council of Educational Research and Training has been rolling out completely new textbooks and an updated syllabus in phases since 2024, and the changes go far beyond a few chapter deletions. New book names, new subjects from Class 6, an Operation Sindoor learning module, restructured history content, corrections in Class 11 and 12 science books, and a full redesign expected for Classes 9 to 12 by 2026-27.
If you are a student, a parent, or someone preparing for JEE or NEET, this blog covers everything that actually matters in one place so you know which edition to study from, what is removed, what is new, and what you need to pay attention to right now.

Why Is NCERT Changing the Syllabus?
The short answer is NEP 2020. The National Education Policy 2020 proposed a complete redesign of school education in India, and the National Curriculum Framework 2023 gave NCERT the detailed blueprint to act on. The old books had not been substantially updated in years, were heavily focused on memorisation, and did not reflect the skill-based, interdisciplinary learning approach that NEP 2020 targets.
The new curriculum pushes for critical thinking, competency-based questions, and practical knowledge. Around 30 percent of older non-essential and repetitive content has been removed across different classes. From 2026, board exams for Classes 10 and 12 will include 50 percent competency-based questions.
1. Content Reduction — roughly 30% of repetitive material removed across classes
2. Exam Alignment — 50% competency-based questions in CBSE boards from 2026 onwards
3. Competitive Accuracy — NEET and UPSC exams now use only the latest rationalized edition data and diagrams
The Phase-by-Phase Rollout: Which Classes Have Changed
| Academic Year | Classes With New Books | Status | Key Change |
|---|---|---|---|
| 2024-25 | Classes 1, 2, 3 and 6 | Completed | First batch of NEP-aligned books. Classes 3 and 6 saw the most significant changes including new book names and restructured content. |
| 2025-26 | Classes 4, 5, 7 and 8 | Current Year | Completely new books with new names. Vocational education added from Class 6. Operation Sindoor and Swadeshi modules added for all classes. |
| 2026-27 | Classes 9, 10, 11 and 12 | Upcoming | Most critical for board exam and competitive exam students. New Class 11 and 12 books expected. JEE 2028 and NEET 2027 aspirants will be the first batch to face the new books. |
| Bridge courses have been introduced for Classes 1, 3, 5, 6 and 8 to help students transition from old to new curriculum without gaps. NCERT has also launched an online Diploma in Teaching of Science for Class 6-8 teachers. | |||
New Book Names for Classes 5 to 8
If you have a younger sibling in Classes 5 to 8, they are now studying from books with completely different names and rewritten content. These are not updated editions of old books. They are entirely new books written from scratch under NCF 2023.
| Class | Subject | New Book Name | Old Book Name |
|---|---|---|---|
| Class 5 | English | Santoor | Marigold |
| Class 5 | Hindi | Veena | Rimjhim |
| Class 6 | English | Poorvi | Honeysuckle |
| Class 6 | Science | Curiosity | Science |
| Class 6 | Social Science | Exploring Society: India and Beyond | History / Geography / Civics (3 separate books) |
| Class 8 | Hindi | Malhar | Vasant |
| Class 8 | Science | Jigyasa / Curiosity | Science |
| Class 8 | Social Science | Exploring Society: India and Beyond | History / Geography / Civics (3 separate books) |
| Class 8 | Vocational | Kaushal Bodh | Did not exist earlier |
| Social Science is now a single integrated subject instead of three separate books. This is one of the most significant structural changes for younger classes under the NEP 2020 framework. | |||
Operation Sindoor Module: New Addition for Classes 3 to 12
One of the most widely discussed additions to the NCERT curriculum in 2025 is the introduction of two special learning modules on Operation Sindoor for students from Class 3 to Class 12.
| Classes | Module Name | Level |
|---|---|---|
| Classes 3 to 8 | Operation Sindoor: A Saga of Valour | Preparatory and Middle |
| Classes 9 to 12 | Operation Sindoor: A Mission of Honour and Bravery | Secondary Level |
Both modules describe the operation as a joint military effort and a patriotic commitment to safeguarding national peace, with reference to the victims of the Pahalgam terror attack. These are positioned as supplementary learning modules to build national awareness among school students.
History Textbook Changes: What Was Removed and Restructured
What Has Been Removed or Changed
Certain chapters and references related to the Mughal period and the Delhi Sultanate have been removed or significantly restructured. The titles "Akbar the Great" and "Tipu Sultan the Great" have been dropped. NCERT stated that the revised curriculum will give more emphasis to India's ancient history, the contributions of tribal communities, and achievements of Indian scientists.
What Has Been Added
The Class 8 Social Science textbook Exploring Society: India and Beyond takes an integrated approach combining history, geography, governance, and economic life in a single subject. The content covers the period from the 13th to the mid-19th century in a multidisciplinary format aligned with NCF 2023.
Vocational Education From Class 6 — A Major Structural Shift
Vocational education is now introduced from Class 6 as a core compulsory subject, not an optional elective. The subject is called Kaushal Bodh and it is now part of the standard curriculum for Classes 6 and 8. Earlier, skill-based education was only available as an optional subject in Classes 9 and above.
Making it a compulsory core subject from Class 6 means millions of students now receive foundational exposure to practical skills and trades alongside their academic subjects from middle school onwards, which is one of the central goals of NEP 2020.
Class 11 and 12 Book Corrections for 2025-26 — Critical for NEET Students
While the major overhaul for Classes 11 and 12 is coming in 2026-27, NCERT has made specific factual corrections to the existing books for 2025-26 that directly affect NEET, where examiners use only the latest edition.
| Subject | Class | Chapter | What Changed | Exam Impact |
|---|---|---|---|---|
| Biology | Class 11 | Photosynthesis | ATP synthase diagram now shows 4 hydrogen ions — not 2 as in older editions | NEET Critical |
| Biology | Class 11 | Cell: The Unit of Life | Theodore Schwann description corrected. Semi-fluid matrix definition updated. | NEET |
| Biology | Class 12 | Human Reproduction | Figure 2.7 (ovary cross-section) now shows "secondary oocyte" instead of "ovum" | NEET Critical |
| Chemistry | Class 11 | Hydrocarbons | Melting point of Eicosane updated to the correct value | JEE / NEET |
| Biology | Class 11 and 12 | Biotechnology chapters | Minor grammatical corrections for conceptual clarity. No topic change. | NEET |
| If your NCERT books were printed before 2024, they may carry the incorrect versions of these diagrams and facts. Download the latest PDFs from ncert.nic.in and check the reprint year on the preliminary pages of your book. | ||||
What Is Coming in 2026-27: The Big Change for Classes 9 to 12
The 2026-27 academic session is when the most consequential change for senior secondary students arrives. NCERT plans to introduce completely redesigned textbooks for Classes 9, 10, 11 and 12. This will be the first time Class 11 and 12 Physics, Chemistry, Biology and Mathematics books have been substantially redesigned since the rationalisation in 2023.
Practical Action for Students Right Now
JEE 2026 and JEE 2027 Aspirants
Your Class 11 and 12 syllabus has not changed for 2025-26. The Chemistry Hydrocarbons correction (Eicosane melting point) is minor but worth verifying by checking the latest edition. Focus on your preparation without worrying about the 2026-27 new books — you will appear before they take effect.
NEET 2026 Aspirants
Verify immediately that your NCERT Biology books are the corrected 2024 or 2025 reprints. Check the Photosynthesis chapter for 4H+ in the ATP synthase diagram. Check the Class 12 Human Reproduction chapter for "secondary oocyte" in Figure 2.7. If your book shows the old values, download the corrected PDFs from ncert.nic.in before your next revision session.
Students Currently in Class 9 or 10
Your current books remain the same for 2025-26. New Class 9 and 10 books are expected in 2026-27. Stay aware of NCERT and CBSE announcements as your Class 11 year approaches. Do not change your current study approach based on upcoming books since their content has not yet been officially published.
