The NCERT recently made major changes. The NCERT changed the Class 9 syllabus and NCERT Books for the session 2026-27 for class 9th. The NCERT already introduced the books of classes 6th to 8th last year. The NCERT class 9 has been introducing modern educational books for students all over India.
The new ninth-grade syllabus has introduced a subject called Earth Science, which can be considered a higher-level version of EVS. This change includes adding a few new chapters to science, while Mathematics has expanded from 12 to 15 chapters. The Writing section has also undergone significant updates. So, thinking that older NCERT books are sufficient is a misconception because almost the entire textbook and CBSE syllabus for ninth grade have been revised for the new academic session.
Class 9 Syllabus Structure
The syllabus is now divided into three major parts: Part A, Part B, and the new Part C. Part A includes language subjects like Hindi, English, Sanskrit, and others. Part B contains core academic subjects such as Science, Mathematics, and Social Science. Part C focuses on overall development, including vocational education, arts, physical education, well-being, and a few chapters integrated into Science and Social Science.
Changes in Science
In Science, there are major changes. In Physics, out of five chapters, four remain, but Gravitation has been removed since it will now be taught in 11th grade. The Work and Energy chapter has been renamed to Work, Energy, and Simple Machines, introducing practical concepts like pulleys and other simple machines.
In Chemistry, the number of chapters has reduced to three, with Matter in Our Surroundings removed because children already learn it in lower classes. The chapter Atoms and Molecules now includes ionic compounds and their properties.
In Biology, Reproduction has been brought to ninth grade, and Diversity in Living Organisms, previously removed, has been reintroduced. Topics related to overall development, such as the muscular-skeletal system, posture care, and nutrition exercises, have also been added.
Under Earth Science, students will now study cycles like water, nitrogen, oxygen, and carbon dioxide, along with radiation and the electromagnetic spectrum. These topics are designed to be interesting and practical for students.
