The short answer

In 2026-27, CBSE Class 9 uses new NCERT books: Ganita Manjari for Maths (14 chapters in two parts), Exploration for Science (13 chapters) and Kaveri for English, with Social Science in two NCERT parts. CBSE's course structure gives Maths 80 marks across six units and Science 80 marks across four units, and each major subject carries 20 marks of internal assessment. The annual exam is set by your school. A compulsory third language (R3) is also new this year. Because chapter names and content have changed, older guides will not match.

What is new in Class 9 this year

  • New textbooks. Maths uses Ganita Manjari, with Part I (8 chapters) and Part II (6 chapters, first published in August 2026). Science uses Exploration (13 chapters, first published in April 2026). English uses Kaveri.
  • Chapters older Class 9 books did not have. CBSE's Maths curriculum includes Sequences and Progressions (arithmetic and geometric progressions, fractals and the Tower of Hanoi), and NCERT's book adds a chapter on algorithms. Other chapters have new names and content, such as Exploring Algebraic Identities.
  • A compulsory third language. R3 is compulsory in Class 9 from 2026-27, assessed by the school. See our three-language policy guide.
  • Application-style questions. CBSE says its question papers are competency-focused, and the Class 9 Maths curriculum lists the same question paper design as Class 10. Read more in our guide to competency-based questions.

Also worth knowing: NCERT's Maths books mark some questions and sections with an asterisk (*) as enrichment, and say these are not to be assessed or included in examinations. Your child can skip them without losing exam marks, though they are good practice for curious students. For a shorter summary of the changes, see what is new in CBSE Class 9 for 2026-27.

How Class 9 is assessed

CBSE's curriculum says the Class 9 annual examination is conducted by the school (80 marks for major subjects), with 20 marks of internal assessment, also run by the school. The assessment scheme is meant to be similar to the Class 10 board examination, and grades in Class 9 use a fixed scale from A1 (91 to 100) down to D (33 to 40). We explain both in our guides to how the 20 internal marks are earned and the CBSE grading system.

Maths: marks by unit and every chapter

One thing to note: CBSE's curriculum lists 15 chapters and NCERT's two parts have 14, and the two lists do not line up word for word. For example, CBSE names separate chapters on Euclid's geometry, lines and angles, and triangles, while NCERT organises its geometry differently and adds a chapter on algorithms. Schools plan around both, so ask your child's school which list its tests follow.

Where children usually need the most support: Geometry carries 25 of the 80 marks, and CBSE's outcomes for it are mostly about explaining why a statement is true, such as the circle theorems and congruence proofs. Algebra carries 20 marks and now includes progressions and factorising quadratic expressions with identities. Statistics now includes weighted averages and stacked bar graphs, and Probability covers empirical and theoretical probability with tree diagrams. Our guide to Class 9 maths tuition covers the warning signs and when extra help makes sense.

Science: marks by unit and every chapter

CBSE's 2026-27 curriculum gives Class 9 Science 80 theory marks across four units, defined by the chapter numbers of NCERT's new Exploration book. The book has 13 chapters, and the first, an introduction to secondary science, is not assigned marks in CBSE's course structure.

UnitChapters in ExplorationMarks
I. World of Living2. Cell: The Building Block of Life; 3. Tissues in Action; 11. Reproduction: How Life Continues; 12. Patterns in Life: Diversity and Classification27
II. Matter: Its Nature and Behaviour5. Exploring Mixtures and their Separation; 8. Journey Inside the Atom; 9. Atomic Foundations of Matter25
III. Motion, Force, Work and Sound4. Describing Motion Around Us; 6. How Forces Affect Motion; 7. Work, Energy, and Simple Machines; 10. Sound Waves: Characteristics and Applications23
IV. Earth as a System13. Earth as a System: Energy, Matter, and Life5

Unit and marks from CBSE's Class 9 Science curriculum for 2026-27; chapter titles from the contents page of NCERT's Exploration, Textbook of Science for Grade 9. Internal assessment adds 20 marks: 5 each for periodic assessment, multiple assessment, a portfolio and subject enrichment (practical work).

The biology units together carry 27 marks, more than any other single unit, which many families do not expect. Matter and Motion together carry another 48 marks. A simple routine is to link every chapter to one experiment or everyday example and ask your child to explain it aloud. Our Class 9 and 10 science tuition guide goes deeper.

English: Kaveri

CBSE's Class 9 English curriculum for 2026-27 prescribes Kaveri: Textbook of English for Grade 9, designed so that the same book can be used at the R1 and R2 levels. The 80-mark paper has three sections: Reading Skills (20 marks), Writing Skills and Grammar (30 marks) and Language through Literature (30 marks), with 20 marks of internal assessment. The reading section includes an unseen descriptive passage and a case-based passage with a chart or other visual data. Our guides on English writing and reading comprehension give simple routines.

Social Science

CBSE's curriculum lists two NCERT Social Science parts for Class 9. At the time CBSE published its Class 9 Social Science document, the course structure for the year was marked as to be provided separately, so ask your school for the chapter list it is following and check cbse.gov.in for updates.

How to plan the year

  1. Get the right books. Confirm with the school that your child has Ganita Manjari Part I and Part II, Exploration, Kaveri and both Social Science parts, and ask for the school's annual plan.
  2. Start with the heaviest units. In Maths that is Geometry (25 marks) and Algebra (20). In Science it is the World of Living unit (27 marks).
  3. Practise explaining. Many outcomes ask students to prove or explain. A child who can say why a theorem is true will cope with unfamiliar questions.
  4. Revise weekly. A short recall of the last chapter prevents the end-of-term pile-up.
  5. Keep internal assessment on track. Twenty marks per subject come from tests, portfolios and projects during the year. See our guide to the 20 internal marks.
  6. Ask early if marks slip. Our guide to improving Class 9 marks gives a parent's action plan, and why Class 9 matters for the boards explains the stakes.

If your child is still in Class 8, our Class 8 syllabus guide shows the foundations that Class 9 builds on.

Where tuition fits

Class 9 is where gaps first begin to cost real marks, and where tuition works best when it targets specific chapters and keeps pace with the school. TutorHive's CBSE online tuition covers maths, science, English and social studies. You can watch a free 30-minute demo class before deciding anything.

A note on sources: marks, units and key concepts come from CBSE's Secondary Curriculum documents for 2026-27 on the CBSE Academic website, and chapter titles from the contents pages of NCERT's textbooks. CBSE and NCERT can update these, and schools may arrange chapters differently, so treat your school's plan as the final word.

Frequently asked questions

Which books does CBSE Class 9 use in 2026-27?
