The changes are part of a phased transition aligned with the National Education Policy (NEP) 2020 and will be implemented gradually until 2031.

On Thursday, April 2, CBSE Chairperson Rahul Singh announced a number of major changes into the curriculum, starting from a three-language policy to advanced-learning subjects.

So what changes for CBSE students in the next four years? Lets us take a deeper look.

Implementation of R1-R2-R3 language framework

CBSE is set to introduce a revised three-language policy built around a proficiency-based system with three levels: R1, R2 and R3. R1 is the highest level, where students are expected to have strong reading, writing and analytical skills. R2 is an intermediate level, while R3 focuses on basic or foundational understanding.

Under the new structure, students will study three languages until Class 10, but at different levels, one at R1, one at R2, and one at R3.

The rollout will happen gradually. R3-level textbooks have been introduced for Class 6 in the 2026-27 academic year and will move up one class each year, reaching Class 10 by 2031. This means the first batch to fully follow this system will appear for their Class 10 board exams in 2031.

For students entering Class 9 in 2026-27, the transition will be partial. They will begin with R1 and R2 level language textbooks right away. By the time they take their board exams in 2028, two languages (at R1 and R2 levels) will effectively be compulsory.

The third language will continue as an optional subject, depending on the school, until around 2030 while the system is being phased in. The 2027 board exams will be the last to follow the current language policy.

CBSE has also introduced additional language options at the Class 9 level from 2026-27, including Maithili, Santali, Dogri and Konkani.

Advanced-level subjects and aptitude-based learning

CBSE is introducing advanced-level courses in Mathematics and Science for students entering Class 9. These are optional and designed for students who want to study subjects at a higher level.

The advanced level will include higher-order thinking questions, more complex concepts, and additional learning material. Students can choose to take these subjects or opt out. They can also select the number of subjects they want to opt for advanced level learning.

The first cohort to take board exams with advanced-level subjects will be in 2028.

CBSE has indicated that the idea is to allow students to identify their aptitude earlier. At present, there is no formal mechanism to identify "gifted" students, and participation will depend on student choice, the CBSE Chairperson said.

AI and computational thinking

AI and computational thinking, which has already been introduced to classes 3 to8 in this academic year, will be extended to Class 9 by 2027-28. Textbooks for class 10 will be prepared by the consecutive academic year to ensure continuity.

Students studying these subjects in Class 9 from the initial rollout will be the first to appear for board exams with these options in 2029.

For classes 11 and 12, these courses will be introduced in form of elective subjects

Compulsory vocational, art and health education

Vocational education will now be compulsory in Classes 9 and 10. Moreover, art education, health education, and physical well-being will also be compulsory.

CBSE will introduce structured textbooks for these subjects, shifting them from activity-based participation to more formal learning. As a result, optional versions of these subjects may be phased out.

However, the assessment for these subjects will remain internal for classes 9 and 10, CBSE added.

The changes will not be implemented all at once. Students over the next few batches will experience a mix of the old and new systems. By 2031, the full framework, including the R1-R2-R3 language system, is expected to be in place.
