CBSE New Curriculum 2026–27 Explained: Big Changes in Subjects, AI & Assessment
CBSE Secondary School
Curriculum 2026–27
A complete, plain-language guide for parents, students & teachers — Classes IX & X, all changes explained simply.
CBSE (Central Board of Secondary Education) has released a new curriculum for Classes IX and X starting from the academic session 2026–27. This is a major update — not just a small tweak.
India's National Education Policy (NEP 2020) said: "Stop teaching children to just mug up and repeat. Help them think, understand, and apply knowledge." This new CBSE curriculum is putting that idea into action for Class IX–X students.
The curriculum is guided by the National Curriculum Framework for School Education (NCFSE 2023) — a government document that tells schools HOW to teach, WHAT to teach, and HOW to test students.
- Cover as many topics as possible
- Memorise answers and write in exam
- Marks = everything
- Same style for all students
- Teach fewer topics but deeply
- Understand and apply knowledge
- Skills + Values + Marks matter
- Flexible choices for students
The curriculum covers eight major areas: Languages, Mathematics, Science, Social Science, Art Education, Physical Education & Well-being, Vocational Education, and the brand-new Computational Thinking & AI.
| What Changed | Old System (2025–26) | New System (2026–27) | Who It Affects |
|---|---|---|---|
| Maths Levels | Maths Basic vs Maths Standard | Maths (common) + optional Maths Advanced | All Class IX & X students |
| Science Levels | One Science paper only | Science (common) + optional Science Advanced | All Class IX & X students |
| CT & AI | Not compulsory | Introduced as modules (compulsory from 2027–28) | Class IX & X students |
| Individuals in Society | Not offered | New subject in Class IX (school-assessed) | Class IX students |
| Languages (R3) | 3rd language not everywhere | R3 (3rd language) compulsory from Class VI 2026–27 | Class VI students (2026 batch) |
| Vocational Education | Work Experience (subsumed in HPE) | Vocational Education as a separate subject with Board exam | All Class IX & X students |
| Art Education | Co-curricular / extra | Core curricular — school-based assessment | All students |
| Board Exam (Class X) | Max 7 subjects for Board exam | Max 7 subjects for Board exam (similar, but new subjects added) | Class X, 2026–27 batch |
Students currently in Class X in 2026–27 can still opt for Maths Basic (as per 2025–26 rules). But from 2027–28 onwards, there is NO more Maths Basic. Instead, all students take the same Maths paper, and those who want more challenge can take an optional Maths Advanced paper of 25 marks extra.
Languages
Hindi, English + 42 other Indian & foreign languages. Focus on listening, speaking, reading, and writing — not just grammar.
80+20 = 100 MarksMathematics
Number systems, algebra, geometry, statistics — taught to develop logical thinking, not just calculations. Optional Advanced paper available.
80+20 = 100 MarksScience
Physics, Chemistry, Biology — through experiments, inquiry, and real-world connections. Optional Advanced paper available.
80+20 = 100 MarksSocial Science
History, Geography, Political Science, Economics — to understand society, rights, duties, and the world around us.
80+20 = 100 MarksArt Education
Visual Arts, Music, Theatre, Dance — now a CORE subject, not just an extra activity. Builds creativity and cultural pride.
School-Based OnlyPhysical Education
Sports, Yoga, fitness, indigenous games, and mental well-being. As important as any academic subject.
School-Based OnlyVocational Education
Practical work skills — like working with machines, materials, or human services. Prepares students for real-world work or further training.
Board Exam in Class XCT & AI (NEW!)
Computational Thinking and Artificial Intelligence — algorithmic thinking, data literacy, ethical AI use. Compulsory from 2027–28 as a full subject.
New from 2026–27Whatever subjects a student chooses in Class IX, they must continue the same in Class X. Students cannot change subjects midway between Classes IX and X.
CBSE now uses a three-language framework labelled R1, R2, and R3. This can be confusing — so here's a simple breakdown:
| Label | Meaning | Example | Level in Exam |
|---|---|---|---|
| R1 | First Language — any language offered by CBSE | English, Hindi, Telugu, Tamil... | R1 level (higher depth) |
| R2 | Second Language — must be DIFFERENT from R1 | If R1 = English, R2 = Hindi or Telugu | R2 level (standard depth) |
| R3 | Third Language — must be different from R1 & R2 | Sanskrit, French, Marathi, etc. | School-assessed (till 2029) |
Out of the three languages, at least two must be Indian languages. For example, you cannot study English + French + German (all foreign). At least two must be Indian — like Hindi, Telugu, Sanskrit, Tamil, etc.
🗓️ When Does R3 Become Compulsory?
| Session | R3 (3rd Language) Compulsory For | Notes |
|---|---|---|
| 2026–27 | Class VI (new students) | Only new Class VI students |
| 2027–28 | Class VI & VII | Same cohort moves up |
| 2028–29 | Class VI, VII & VIII | — |
| 2029–30 | Class VI, VII, VIII & IX | R3 enters secondary level |
| 2030–31 | Class VI through X | Fully implemented |
Students already in Class IX/X must have passed a 3rd language in Class VIII. If they couldn't clear it in Class VIII, they get another chance in Class IX. If still not cleared, one more chance in Class X. No student can appear in the Class X Board exam without passing the 3rd language.
Until NCERT creates separate R1/R2 level books, students at both R1 and R2 levels will use the same textbook (e.g., Kaveri for English Class IX). However, the syllabus coverage and exam difficulty will be different for R1 and R2.
This is one of the biggest changes in 2026–27. Maths and Science are now offered at two levels:
📘 Standard Level (Compulsory)
- All students must take this
- Common syllabus for everyone
- 80 marks paper, 3 hours
- Annual exam by school (Class IX)
- Board exam by CBSE (Class X)
- Plus 20 marks internal assessment
- Only for students who want extra challenge
- Additional topics beyond standard
- 25 marks extra paper, 1 hour
- ALL questions are HOTS (Higher Order Thinking)
- Available from Class X (2027–28 onwards)
- Marks NOT added to total aggregate
| Question | Answer |
|---|---|
| Do I have to take the Advanced paper? | No — it's completely optional. You can take both, one, or neither. |
| Do Advanced marks improve my aggregate? | No. Advanced marks are NOT added to your total score/percentage. |
| What do I get if I pass Advanced? | A special mention on your marksheet: "Advanced Level successfully cleared" (if you score 50%+). |
| What if I score below 50% in Advanced? | Nothing is mentioned on the marksheet. No penalty at all. |
| Can I take Advanced for just one subject? | Yes. You can take Maths Advanced only, or Science Advanced only, or both, or neither. |
| Is Maths Basic still available in 2026–27? | Only for current Class X students of 2026–27. From 2027–28, Maths Basic is discontinued. |
This is the most futuristic addition to the CBSE curriculum. CBSE wants every student — not just computer science students — to understand how computers think and how AI works.
| Classes | What Happens | Session |
|---|---|---|
| Classes III–V | Computational Thinking (CT) woven into existing subjects — logical thinking, patterns, sequences. No separate class needed. | From 2026–27 |
| Classes VI–VIII | Advanced CT + basic AI literacy through worksheets, projects, activities. Low-tech, activity-based. No gadgets required. | From 2026–27 |
| Classes IX–X | CT & AI introduced as MODULES (compulsory). School-based assessment initially. | From 2026–27 (modules) |
| Classes IX–X | CT & AI becomes a full subject with Annual/Board examination. | From 2027–28 onwards |
- Logical reasoning and algorithmic thinking (how to solve problems step-by-step)
- Pattern recognition and data interpretation
- How AI systems work and how to use them ethically
- Digital literacy and responsible use of technology
- Creativity and collaboration using technology tools
CBSE has clearly stated that CT & AI teaching will remain low-tech and activity-driven for now. It will be embedded within existing subject periods. Schools are NOT required to buy new computers or subscribe to platforms.
For most major subjects, the total marks are 100, split into two parts:
- Class X: Board exam conducted by CBSE
- Class IX: Annual exam conducted by the school
- 3-hour paper based on full syllabus
- Must score 33%+ here separately
- Done by the school throughout the year
- Includes tests, projects, activities, portfolio
- Applies to both Class IX and X
- Must score 33%+ here separately
A student must score at least 33% in the external exam AND 33% in the internal assessment. Scoring very high in one cannot compensate for failing the other. BOTH are mandatory.
📋 Nature of Question Papers (What Type of Questions to Expect)
| Section | Type of Questions | Approximate Share |
|---|---|---|
| Section A | MCQs — Multiple Choice Questions (objective type) | ~20% |
| Section B & C | Short answer questions | ~30% |
| Section D | Long answer questions | ~20% |
| Section E | Case-based / source-based questions (real situations) | ~30% |
| Overall | ~50% questions are Competency-Based (apply knowledge, not just recall) | 50%+ |
Instead of asking "Define photosynthesis," a competency question might say: "A farmer notices plants near a dirty river are growing slowly. Using your knowledge of photosynthesis and soil nutrients, explain two possible reasons and suggest solutions." — You need to THINK and APPLY, not just recall.
Class X — 9-Point Grading (Position-Based)
CBSE puts all passed students in rank order and assigns grades like this:
Top 1/8
Next 1/8
Next 1/8
Next 1/8
Next 1/8
Next 1/8
Next 1/8
Last 1/8
Fail
For Class X, your grade depends on your rank among all students who passed nationally — not just your raw marks. This is called "positional grading."
Class IX — Marks-Based Grading (Absolute)
Class IX uses fixed marks ranges — your grade depends only on YOUR marks:
| Marks Range | Grade |
|---|---|
| 91 – 100 | A1 |
| 81 – 90 | A2 |
| 71 – 80 | B1 |
| 61 – 70 | B2 |
| 51 – 60 | C1 |
| 41 – 50 | C2 |
| 33 – 40 | D (Pass) |
| Below 33 | E (Fail) |
Class IX schools have smaller batches — positional grading doesn't work well with few students. So absolute marks-based grading is used instead. For large national-level Board exams (Class X), positional grading is fairer and more meaningful.
The 20 marks of Internal Assessment are divided equally into 4 parts of 25% each:
Periodic Assessment
3 tests conducted during the year. Best 2 are counted. At least 1 must be competency-based (case study / problem-solving style).
Multiple Assessment
Varied activities: oral presentations, quizzes, group projects, experiments, concept maps, fieldwork, debates, discussions.
Portfolio
A collection of student's best work throughout the year — written work, art-integrated tasks, projects, reflections, experimental records.
Subject Enrichment Activities
Subject-specific deep work — e.g., Science lab experiments, Social Science civic projects, Language speaking/writing activities.
What Goes Into Each Component?
| Component | Subject | Examples of Activities |
|---|---|---|
| Subject Enrichment | Languages | Listening exercises, speaking tasks, debate, analytical writing, reading aloud |
| Science / Maths | Lab experiments, hypothesis testing, data analysis, modelling | |
| Portfolio | All subjects | Written assignments, reflections, art-integrated tasks, project reports, creativity samples |
| Multiple Assessment | All subjects | Group work, quiz, observation by teacher, peer assessment, role play, fieldwork |
| Periodic Tests | All subjects | 3 tests during the year; best 2 counted; at least 1 should have case-based / open-ended questions |
The portfolio is NOT a bulky file of everything you do. CBSE clearly says: "A limited number of thoughtfully selected artefacts." It is judged on Organisation/Creativity, Evidence of Growth, and Completeness — not on how thick the file is.

Accommodation means changing HOW a student is tested — not WHAT is tested. The content and standards remain the same. This is what CBSE provides. Modification means changing the difficulty level itself — CBSE does not do this, to ensure all students are held to the same learning standards.
CBSE is not changing everything at once. The new curriculum is being introduced in phases. Here's the complete timeline:
CBSE is being careful. Changing everything at once would confuse students, teachers, and parents. The phased approach lets schools and students adapt slowly, ensuring proper training for teachers, availability of new NCERT textbooks, and smooth transition without disruption to existing students.
CBSE is very clear: marks alone are not the goal. The curriculum aims to develop well-rounded human beings. Here are the key skills students are expected to build:
📘 Learning Skills (4Cs)
- Critical Thinking
- Creativity
- Communication
- Collaboration
📡 Literacy Skills
- Information Literacy
- Media Literacy
- Technology Literacy
🌱 Life Skills
- Flexibility
- Leadership
- Initiative
- Productivity
- Self-awareness
Constitutional Values Embedded in All Subjects
| Value | How It Appears in Curriculum |
|---|---|
| Justice | Social Science, debates, case studies on rights and equality |
| Liberty | Language activities, open-ended projects, student choice in learning |
| Equality | Inclusive classroom, mixed group work, representation in textbooks |
| Fraternity | Team sports, art-integrated learning, community engagement projects |
| Environmental Responsibility | Environmental Education (Class X), Science, cross-curricular linkages |
| Gender Sensitivity | Lesson plans must include gender sensitivity; textbook review by School Curriculum Committee |
| Fundamental Duties | Art Integrated Projects, Constitution Day, Social Science, cross-curricular projects |
🏆 Student Activities CBSE Organises Nationally
| Activity | Skills Developed |
|---|---|
| Story Telling Competition | Creative thinking, analytical thinking |
| Aryabhata Ganit Challenge | Reasoning, problem solving, critical thinking, logical arguments |
| CBSE Heritage India Quiz | Cultural awareness, respect for diversity, critical thinking |
| Science Exhibition & Science Challenge | Scientific temperament, creativity, connecting science to daily life |
| Art Integrated Project | Multidisciplinary thinking, creativity, experiential learning |
| Ek Bharat Shrestha Bharat | Patriotism, cultural exchange, unity |
| Fit India School Week / CBSE Games | Physical fitness, healthy lifestyle, teamwork |
| International Day of Yoga | Mental well-being, mindfulness, Indian knowledge tradition |
| Matri Bhasha Diwas | Linguistic diversity, cultural traditions, communication |
| Constitution Day (Nov 26) | Constitutional awareness, Fundamental Rights and Duties |
| Area | What CBSE Expects from Teachers |
|---|---|
| Lesson Planning | Write detailed lesson plans with: Learning Outcomes, Pedagogical Strategies, Group Activities, Interdisciplinary Links, Gender Sensitivity, Resources (including ICT), Assessment Items, Feedback Plan, Inclusive Practices |
| Teaching Style | Be a FACILITATOR, not a lecturer. Use: inquiry-based learning, discussions, debates, art-integrated tasks, real-life examples, local contexts, case studies, simulations, project-based learning |
| Assessment | Use case-based, source-based, application questions in tests. Conduct regular formative assessments. Maintain portfolios and project evidence. Prepare Holistic Progress Cards (HPC). |
| Training | Minimum 50 hours of professional development training per year is mandatory. Must regularly check CBSE Academic website, DIKSHA, NISHTHA modules, NCERT resources. |
| Mental Health | Identify early signs of stress or anxiety in students. Create emotionally safe classrooms. Refer students to counsellors when needed. Support exam stress management. |
| Inclusion | Never label students "slow" or "bright." Adapt pedagogy for each student's needs. Ensure CwSN students have all required accommodations. |
| Technology | Use DIKSHA, educational videos, virtual simulations where useful — but technology is a TOOL, not the end goal. Strong teacher-student relationship must be preserved. |
| Values | Lead by example in demonstrating constitutional values, empathy, environmental responsibility, gender sensitivity, and democratic attitudes. |
CBSE mandates every school to form a School Curriculum Committee with teachers from each subject area. This committee: plans pedagogy, designs assessments, reviews textbooks for age-appropriateness, ensures gender sensitivity, checks for constitutional compliance, and sends a final list to the Principal.
📌 In Summary — Key Points Every Parent & Student Must Know
- Maths Basic is being phased out. All students take one Maths paper — and can optionally attempt the Advanced paper for an honourable mention.
- Class IX results no longer go to CBSE Board — but they are still serious annual examinations conducted by the school.
- Three languages will be compulsory for Class IX students from 2029–30. For now (2026–27), only Class VI students starting R3 will be affected.
- CT & AI is compulsory from 2027–28 as a full subject — start building awareness of computational thinking and AI now.
- 50% of exam questions test your ability to APPLY knowledge — not just repeat it. Reading and understanding matter more than memorisation.
- Art, Physical Education, and Vocational Education are now as important as academics. Schools must give them proper time in timetables.
- Internal Assessment (20 marks) is serious — it has 4 components throughout the year. Don't ignore it.
